Hi,
I have a 2004 Mazda 6 and for the past 2 day my engine check light is on. When I took it to the dealer they said its due to open thermostat valve. Wondering, how much does it cost to replace it with a new one?
and what is the part number suitable for 2004 Mazda 6- 4 cylinder?

Pls. reply

Thanks
Joey

on the V6 it is 3 bolts and about 30 seconds of work....... minus draining the exsisting coolant.

Not sure about the 4 cylinder, but like flip said the V6 is a piece of cake. If the 4 cylinder is like the V6, I would imagine a shop would still probably charge an hours worth of labor, which depending where you go could be close to $100. The thermostat itself is less than $10. Of course, I don't know your mileage but it may be a good idea to flush your coolant system while you're at it.

the Tstat and gasket cost me 14 bucks and change with tax IIRC. I went big league and went with the Tstat with a life time warranty..... the one with a 1 year is cheaper.
