2008 Mitsubishi Galant
Vehicle Specs & Maintenance Data
The 2008 Mitsubishi Galant maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Mitsubishi Galant.
For oil changes, the 2008 Mitsubishi Galant takes 0W-20 Full Synthetic motor oil with a capacity of 4.5 quarts. Brake fluid type is DOT 3, the recommended coolant is Dia Queen Super Long Life Coolant (Green), and transmission fluid is Diamond ATF SP-III. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Mitsubishi Galant, torque the lug nuts to 80 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.
Owners of the 2008 Mitsubishi Galant have reported 5 common issues including "Timing Belt and Tensioner Failure", "Automatic Transmission Harsh Shifting" and "Electrical System and Alternator Issues".

Common problems reported by 2008 Mitsubishi Galant owners, with recommended fixes and estimated repair costs.
Timing Belt and Tensioner Failure
The 2.4L 4G69 engine uses a timing belt that requires replacement at 60,000-mile intervals. If the belt is neglected, it can break or jump teeth, causing catastrophic interference engine damage with valve-to-piston contact. The hydraulic belt tensioner and idler pulleys are also failure-prone components that can cause belt failure even if the belt itself is not worn.
Replace the timing belt, hydraulic tensioner, idler pulleys, and water pump as a complete service every 60,000 miles. The water pump is driven by the timing belt and should always be replaced at the same time. Use OEM Mitsubishi or premium aftermarket timing components. This is a critical maintenance service that should not be deferred.
Est. Cost: $500 - $900Automatic Transmission Harsh Shifting
The 4-speed automatic transmission can develop harsh shifts, delayed engagement, and slipping between gears. The transmission may bang into gear when shifting from park to drive, or slam into second gear during upshifts. The issue worsens with mileage and can lead to complete transmission failure if not addressed.
Perform a transmission fluid and filter change using Mitsubishi SP-III ATF. A solenoid pack replacement can resolve harsh shifting caused by worn solenoid valves. If internal damage is present (burnt clutch packs), the transmission will need a rebuild or replacement with a remanufactured unit.
Est. Cost: $200 - $3,500Electrical System and Alternator Issues
The electrical system can develop multiple issues including alternator failure, parasitic battery drain, and faulty body control module behavior. Symptoms include dimming headlights, battery warning light, dead battery after sitting overnight, intermittent power window operation, and erratic dashboard warning lights.
Test the charging system output and battery condition. Replace the alternator if output is below specification. Perform a parasitic draw test to identify any circuits drawing excessive current while the vehicle is off. Common culprits include the trunk light switch, radio, and glove box light. Inspect all ground connections for corrosion.
Est. Cost: $200 - $700Front Lower Control Arm Bushing Wear
The front lower control arm bushings wear out prematurely, causing clunking noises over bumps, a vague or wandering steering feel, and accelerated inner tire wear from alignment shifting. The rubber bushings crack and deteriorate, particularly in vehicles driven on rough roads or in cold climates with road salt exposure.
Replace the front lower control arms or press in new bushings. It is generally more cost-effective to replace the entire control arm assembly since the ball joints are pressed in and may also be worn. Perform a four-wheel alignment after replacement. Inspect the sway bar end links and strut mounts while the front end is disassembled.
Est. Cost: $300 - $700AC System Refrigerant Leak
The AC system develops refrigerant leaks from the condenser, evaporator core, and compressor shaft seal. The system gradually loses cooling capacity over a season, requiring annual recharging. A slow leak at the evaporator core is particularly difficult to diagnose and expensive to repair because of the dashboard removal required for access.
Perform a leak detection test using UV dye and an electronic leak detector. Replace the leaking component: condenser ($300-600), compressor ($600-1,000), or evaporator ($800-1,500 due to labor). Recharge the system and verify pressures. Annual AC system inspections can catch leaks before they worsen.
