What's the life span of the thermostat
Took my car in with the engine light on and was told the thermostat need changing. Done that. Now 2 years later took it in with the same problem and told the same thing and have it replace with gasket and all. Did I have a faulty thermostat in the 1st replacement or the workmanship. 1st replacement was at 65,000+ km, now it has 85,000 km. Shouldn't the thermostat last longer than 20,000km?
