Timing Belt Issues

Another potential issue with the 2006 Mitsubishi Eclipse V6 is related to the timing belt. The 6G72 engine uses a timing belt, which needs to be replaced at regular intervals, typically every 60,000 to 90,000 miles. If the timing belt breaks, it can cause catastrophic engine damage, as the pistons can collide with the valves. Symptoms of a worn timing belt include a ticking noise from the engine, rough running, and difficulty starting. It's crucial to adhere to the recommended replacement schedule and have the timing belt inspected regularly. If you're buying a used 2006 Eclipse V6, be sure to ask for documentation showing when the timing belt was last replaced. Replacing the timing belt is a relatively involved job, but it's much cheaper than replacing the entire engine. Don't neglect this important maintenance item!

Catalytic Converter Failure

Catalytic converter failure is another common problem that can plague the 2006 Mitsubishi Eclipse V6. The catalytic converter is responsible for reducing harmful emissions from the exhaust system. Over time, it can become clogged or damaged, leading to reduced engine performance and a failed emissions test. Symptoms of a failing catalytic converter include a rotten egg smell from the exhaust, reduced acceleration, and a check engine light. If you suspect your catalytic converter is failing, it's important to have it inspected and replaced as soon as possible. Driving with a bad catalytic converter can further damage the engine and reduce fuel economy. Replacement catalytic converters can be expensive, but there are aftermarket options available that can save you some money. Be sure to choose a quality replacement to ensure proper performance and longevity.
