Maintaining Your MITSUBISHI DIAMANTE/MAGNA i

Regular maintenance is key to the longevity of your MITSUBISHI DIAMANTE/MAGNA i. Here's a look at some key areas to focus on:
• Engine Oil: Regular oil changes are crucial for engine health. Consult your owner's manual for the recommended oil type and change interval.

• Ignition System: Ensure the ignition module and distributor cap are in good condition for optimal engine performance.
• Air Intake: Maintaining a clean air mass meter contributes to fuel efficiency and engine performance.
• Cooling System: Inspect radiator hoses (especially the lower hose) regularly to prevent leaks and overheating.
• Suspension: Keep an eye on suspension bushes, particularly the rear control arm lower bushes, as these can affect handling and ride comfort.
