Re: 2.4 Jtd engine temp
It may not be your thermostat but the gauge itself.
My 1.9JTD shows just over the line between 50 and 90 (assume 70 if linear). I bought an ELM OBD reader to check this and confirmed that the water temp was in fact ~85 when the gauge read 70. I am also pretty sure stat is ok as could see that the water temp dropped a little as it rose to 85ish (as the stat opened and cool water entered the system from the radiator).
Just a thought - there are also threads showing that others are experiencing an inaccurate temp gauge.
Edit: If you're ever down in the Stockport area, drop me a PM and we can plug the OBD reader in to check your temp - assuming your car is compatible (Post 2003 I think?).
