How to Replace Mitsubishi Headlights

Mitsubishi headlight replacement is straightforward on most models. Whether replacing standard halogen units or upgrading to HID or LED headlights, this guide covers Outlander, Lancer, L200, ASX, and Shogun models.

Step-by-Step Instructions:

1. Open the bonnet and secure it safely. Locate the rear of the headlight assembly from within the engine bay. On Outlander and ASX models, access is excellent with generous engine bay space. On L200 pickups, the higher bonnet line provides clear access to headlight mountings. Lancer models have accessible headlight assemblies despite compact engine bay layout.
2. Disconnect all electrical connectors. Mitsubishi headlights typically have 2-3 electrical connectors depending on specification. These include main beam, dipped beam, and side light connections. On models with HID or LED headlights, there may be additional connectors for ballasts or control modules. Press the release tabs carefully and pull straight out to disconnect each connector. Label connections if needed for easier reinstallation.
3. Remove the headlight mounting bolts. Most Mitsubishi models use 10mm bolts to secure the headlight assembly. On Outlander and ASX, there are typically 3-4 mounting bolts along the top edge easily accessible once the bonnet is open. On Lancer models, expect 2-3 bolts with straightforward access. L200 pickups have robust mounting with 3-4 bolts clearly visible. Remove all mounting bolts completely and keep them organized for refitting.
4. Release any additional clips or retainers. Some Mitsubishi headlights use supplementary plastic clips at various points for additional security. On Outlander models, check for clips at the inner corner near the grille. On L200 and Shogun models, look for clips at the outer edge. Work carefully as plastic clips can become brittle with age especially on older models.
5. Carefully remove the headlight assembly. With all bolts and clips released, gently pull the headlight straight forward out of its mounting position. Mitsubishi headlights typically slide forward on locating pins that ensure correct alignment. Support the weight as you pull to prevent dropping the assembly. If you feel resistance, stop immediately and check for missed fixings rather than forcing removal which could crack the housing.
6. Transfer components to new headlight if needed. If your replacement doesn't include bulbs or ballasts for HID systems, carefully transfer these from the old unit. When handling bulbs, wear clean gloves to avoid touching glass surfaces with bare hands as skin oils cause premature failure and hot spots. Check bulb condition and replace if worn.
7. Install the new headlight assembly. Reverse the removal process by aligning the new headlight with mounting pins and push firmly into place ensuring all locating pins engage correctly in their housings. Refit all mounting bolts and tighten securely but avoid overtightening plastic mounting points. Reconnect all electrical connections ensuring each clicks firmly into place. Test all lighting functions before final assembly including dipped beam, main beam, side lights, and indicators to confirm proper operation.

Important Notes: Mitsubishi headlight replacement is straightforward on most models with good access. When handling new headlights, never touch lens or reflector surfaces as fingerprints affect light output. HID headlights may require coding to the ECU to avoid warning lights on some models. Check headlight alignment after fitting using adjustment screws on the rear of the assembly for optimal visibility and MOT compliance.

How to Replace Mitsubishi Front Bumper

Replacing a Mitsubishi front bumper is achievable in 45-90 minutes depending on model. This process covers Outlander, Lancer, L200, ASX, and Shogun models, though specific screw locations vary between generations.

Step-by-Step Instructions:

1. Open the bonnet and secure it with the prop rod. Locate the upper bumper mounting fixings along the top edge just below the grille area. Most Mitsubishi models have 4-8 screws or bolts securing the bumper along the top. On Outlander and ASX models, these are typically Phillips or 10mm bolts easily visible. On L200 pickups, expect more robust fixings with 6-8 bolts across the top. Lancer models typically use Phillips screws. Remove all upper fixings systematically and keep organized.
2. Access the wheel arch areas on both sides. Turn the steering wheel fully to one side to maximize access to the wheel arch liner. Behind each front wheel, locate the plastic arch liner securing clips and screws. Remove or release 3-5 plastic clips or screws securing the front section of the liner to expose side bumper mounting points. Mitsubishi uses plastic push-in clips that release by pressing the center pin first before pulling the entire clip. Repeat on both driver and passenger sides.
3. Remove the side mounting screws from both wheel arches. Behind each wheel arch liner, you'll find 2-4 screws or bolts securing each side of the bumper to the wing. These are usually 10mm bolts or Phillips screws on Mitsubishi models. Remove all side fixings on both driver and passenger sides completely. Keep track of which fixings came from which side as they may differ between left and right.
4. Remove undertray screws and lower bumper fixings. Get underneath the vehicle safely using ramps or jack stands never work under a vehicle supported only by a jack. Locate and remove all screws and clips securing any engine undertray and the lower edge of the bumper. Mitsubishi typically uses 8-12 fixings along the bottom edge. These may be Phillips screws, 10mm bolts, or plastic push-in clips depending on model. You don't always need to remove the entire undertray just the front section.
5. Disconnect fog lights, sensors, and electrical connections. Reach behind the bumper and disconnect all electrical connectors including fog lights if fitted typically one connector per side, parking sensor connections if equipped with parking assist usually 4 sensors across the bumper, and any additional connections for cameras on newer models or washer jets. Press release tabs carefully and pull straight out. Count connections as you disconnect to ensure you reconnect them all during refitting.
6. Release the bumper side clips and mounting tabs. Mitsubishi bumpers are secured by plastic clips or metal brackets on each side that slot into the wing panels. With all visible fixings removed, firmly but gently pull the bumper forward from one corner while supporting the opposite side. You may need to wiggle slightly side-to-side to release the clips from their mounting points. Listen for clicks as clips disengage from wings.
7. Remove the bumper completely from the vehicle. With all fixings removed and clips released, carefully pull the bumper straight forward away from the vehicle supporting it evenly. Mitsubishi bumpers are reasonably lightweight on Lancer and ASX models but Outlander, L200, and Shogun bumpers are heavier and benefit from a second person due to size and weight. Place the removed bumper on a protected surface like cardboard or blankets to avoid scratching the painted surface.
8. Prepare and fit the replacement bumper assembly. Before installation, transfer any brackets, trim pieces, number plate mounting, or components from the old bumper if not fitted to your replacement part. Align the new bumper with mounting points and push firmly into place ensuring all side clips engage properly into the wing mounting points. Reconnect all electrical connections including fog lights and parking sensors ensuring each clicks firmly. Systematically secure with all screws, bolts, and clips in reverse order of removal. Test all electrical functions before final assembly including fog lights and parking sensors. Check panel gaps are even on both sides and adjust if needed.

Top Tips: Mitsubishi bumpers are designed for practical replacement with straightforward access. When refitting parking sensors, ensure each clicks firmly into its mounting hole and is correctly aligned flush with the bumper surface for proper operation. On models with front-mounted cameras for parking assist or 360-degree view systems, these may require recalibration at a Mitsubishi specialist after bumper replacement. Check all panel gaps between bumper and wings are even before final tightening of all fixings.

Common Mitsubishi Parts Problems & Solutions

Mitsubishi vehicles are renowned for exceptional value and reliability. The brand ranked 6th out of 32 car brands with a RepairPal reliability rating of 4.0 out of 5.0, with average annual repair costs of just £535 versus £652 industry average and only 0.2 shop visits per year versus 0.4 industry average. In the 2023 J.D. Power Vehicle Dependability Study, Mitsubishi ranked 4th among mass-market brands, ahead of Toyota. However, certain components can experience specific issues. Here are the most commonly reported Mitsubishi parts problems based on verified data from UK owners, mechanics, and industry specialists.

CVT Transmission Problems (2014-2018 Outlander) - Critical Issue:

• Affected Models and Symptoms: The continuously variable transmission in Outlander models particularly 2014-2016 model years has been reported to cause jerking during acceleration, stalling at low speeds or when stopping, overheating especially under heavy load or hot weather, shuddering and hesitation during gear changes, and complete transmission failure in severe cases. Some owners experienced complete transmission failure requiring costly replacement. Mitsubishi extended the warranty on some CVT transmissions in response to widespread issues.
• Root Causes: CVT problems stem from several factors including transmission fluid overheating which degrades fluid viscosity and film strength, incorrect fluid specifications third-party fluids claiming compatibility but causing damage, inadequate fluid changes Mitsubishi claims lifetime fluid but CVT manufacturers recommend changes every 30,000 miles, belt and variator wear from aggressive driving or heavy loads, and oil degradation counter not being reset during fluid changes leading to incorrect TCM calibration.
• Critical Fluid Requirements: Mitsubishi CVTs require Dia Queen CVTF-J4 fluid exclusively. Using third-party fluids even those claiming J4 compatibility causes internal damage to clutch discs, valve bodies, and solenoids. In the event of CVT failure, Mitsubishi requires fluid samples sent to laboratory for analysis to confirm their fluid was used before warranty coverage. Aftermarket fluid can be detrimental to these systems and will void warranty claims. Always keep receipts clearly stating fluid name and part number for warranty proof.
• Replacement Costs and Prevention: CVT transmission replacement costs £6,000-£8,000 plus labour at dealerships making this one of the most expensive Mitsubishi repairs. To prevent CVT failure, change CVT fluid every 30,000 miles using only genuine Dia Queen J4 fluid despite Mitsubishi's lifetime fluid claims. Avoid harsh acceleration and heavy throttle applications which cook the fluid. Drive CVT-equipped vehicles gently with calm smooth inputs avoiding jerky torque applications. Have the CVT oil degradation counter reset using Mitsubishi diagnostic tool during fluid changes as this value tells the TCM appropriate operation levels. Regular fluid changes are critical cheap insurance against catastrophic £6,000+ failure.

Excessive Oil Consumption (2014-2016 Models):

• Affected Engines: Some Outlander models particularly 2014-2016 versions with 2.4-litre four-cylinder engines and certain Lancer models with 1.5-litre 4A91 engines have been reported to consume excessive oil. This issue is linked to piston ring wear or faulty valve seals allowing oil to burn in combustion chambers.
• Warning Signs: Blue smoke from exhaust especially on startup or acceleration, low oil level warnings appearing frequently between service intervals, oil level dropping noticeably between changes requiring top-ups, and reduced engine performance or rough running. If unaddressed, excessive oil consumption leads to engine damage from inadequate lubrication.
• Solutions: Monitor oil levels weekly especially on affected model years. Top up oil promptly when levels drop below minimum mark. In severe cases, piston ring replacement or valve seal replacement may be necessary costing £800-£2,500 depending on extent of work. Regular oil changes using quality oil can slow progression but won't fix worn rings or seals. Some owners have success using slightly thicker oil viscosity to reduce consumption though always stay within manufacturer specifications.

Premature Brake Wear (2014-2018 Outlander):

• Early Brake Pad Wear: Certain Outlander models including 2014-2018 range have shown premature brake pad wear with some owners needing replacements as early as 15,000-20,000 miles significantly earlier than expected. Brake noise including squealing and screeching when cold is also common on Outlander models.
• Causes: Premature wear stems from sticking brake callipers, glazed brake rotors, inadequate pad cushioning hardware, and aggressive braking habits. Cold brake noise results from vibration between pads and rotors especially with glazed surfaces.
• Solutions: Inspect brake pads, rotors, and callipers regularly during service intervals. Replace worn brake pads in axle pairs for balanced braking never replace single side. Resurface or replace glazed brake rotors. Install fresh pad hardware shims and clips with proper lubrication on contact points. If callipers stick, rebuild or replace them. Allowing brake noise to continue wears pads unevenly and reduces stopping effectiveness. Regular brake maintenance prevents premature wear and ensures safe braking performance.

Rust and Corrosion Issues (2002-2008 Lancer):

• Severe Subframe Rust: The 2008 Mitsubishi Lancer and models from 2002-2008 are known for subframe corrosion, one of the worst problems affecting these vehicles. The subframe is a critical suspension component holding the engine and front wheels. In affected units especially in areas using road salt for winter de-icing, subframes developed severe corrosion with cracks or holes undermining structural strength. Eventually rotted subframes can fail catastrophically without warning creating serious safety hazards. This problem was so severe that Mitsubishi recalled 2002-2008 model year Lancers with faulty subframes.
• Other Rust-Prone Areas: Beyond subframes, older Mitsubishis particularly Lancer models are prone to rust around wheel arches and rocker panels, door sills and lower door edges, underbody and floor panels, and rear arches. Japanese import versions lack European corrosion protection as Japanese roads aren't salted in winter making imports more vulnerable to UK winter conditions.
• Prevention and Treatment: Regularly check underneath the vehicle and remove dirt or debris that traps moisture causing rust. Treat any rust flakes early with wire brush or sanding to remove corrosion followed by anti-rust primer and touch-up paint. For severe corrosion, replacement panels may be necessary. Rustproofing treatments and undersealing provide protection for older models. When buying used Mitsubishis especially pre-2010 models, thoroughly inspect subframe and underbody for rust before purchase.

Suspension Component Wear (Lancer and Outlander):

• Premature Suspension Wear: Early Outlander models from 2007-2013 are known to experience premature wear in front suspension particularly control arms and ball joints. Some Lancer models also experience premature strut and shock absorber wear, control arm bushing wear causing clunking noises, and steering vibrations at higher speeds often linked to alignment or suspension issues.
• Symptoms: Knocking noises from front suspension over bumps, alignment issues causing vehicle to pull to one side, rougher ride quality and increased road noise, and vibrations through steering wheel especially at speed. Worn suspension affects handling stability and tyre wear.
• Solutions: Inspect suspension components regularly during service intervals. Replace worn control arms, ball joints, bushings, struts, and shock absorbers as needed. Always replace suspension parts in pairs for balanced handling. After replacement, perform wheel alignment to proper specifications. Regular alignment checks prevent uneven tyre wear and maintain proper handling characteristics.

Automatic Transmission Issues (Lancer 2008-2011):

• Transmission Problems: Some 2008 Lancer models experienced transmission overheating leading to transmission slippage while driving. Several units slipped into wrong gears without warning and electronic dashboard incorrectly indicated transmission position creating dangerous situations. While some attempted fixes with transmission oil changes, others required complete transmission replacement at significant cost.
• Sealed Automatic Gearboxes: Automatic gearboxes in Lancer models are sealed units meaning minor repairs aren't possible and entire gearbox requires replacement when problems develop. This makes transmission issues particularly expensive. Regular transmission fluid changes on schedule help prevent overheating and extend gearbox life.

Electrical System Issues (Various Models):

• Battery Drain: Some models experience electrical system malfunctions causing parasitic battery drains even when vehicle is off. Faulty batteries in some models drain faster than expected sometimes due to electrical draws from components.
• Dashboard Warning Lights: Problems with sensors often trigger erroneous warning lights for engine, ABS, or airbags when no actual fault exists. Power window failures from faulty regulators or motors are occasionally reported. Electrical issues require diagnostic testing to identify root causes.

Drive Belt Wear (2008-2011 Lancer - Recall):

• Drive Belt Failure: Lancers manufactured between December 2007 and February 2009 were recalled for drive belt issues. Belts made from incorrect material wore at angles causing them to slip off pulleys leading to engine overheating, battery discharge resulting in engine stall, and difficult steering from power steering pump failure. This recall affected 2008-2011 Lancer, Lancer Evolution, Lancer Sportback, and Outlander models with 4B1 engines. Dealers replaced drive belts with proper rubber belts and excessively worn pulleys free of charge.

Air Conditioning Problems (Outlander):

• AC Compressor Failure: Several Outlanders particularly in hot climates have had problems with air conditioning compressor failing prematurely leading to high repair costs. Heater core leaks in certain 2014-2017 models cause poor heating performance and in some cases contribute to engine overheating.

Mitsubishi Reliability Assessment:

Overall Excellent Value and Reliability: Mitsubishi's reliability is excellent particularly considering affordable pricing. RepairPal ranks Mitsubishi 6th out of 32 car brands with 4.0 out of 5.0 rating and average annual repair costs of just £535 versus £652 industry average. Shop visits average only 0.2 times per year versus 0.4 industry average, and severe repairs are 12% versus 12% industry average. In the 2023 J.D. Power Vehicle Dependability Study, Mitsubishi ranked 4th among mass-market brands, ahead of Toyota demonstrating exceptional reliability.
