Hi everyone. Soon, I'll upgrade the coolant system of my car. So, I install a new biggest radiator, a water pump Bosh 010, new valley pipe and new coolant tank. I must change also the temperature water sensore, and the thermostat. For this one, I'm thiking about an component different to the stock piece. Have you know about an performance low temperature thermostat to my car (2003 XJ Supercharged 4.2)? Here it's possible to find a "performance component" by Eurotoys.

But I don't have proof that this is an specific aftermarket components, for me it may be a normal stock components. So, spend about 40€ (plus shipping) to a -possible- stock component, is not a good thing. What do you say? Thanks so much!

 

Don't. The engine is meant to run at the temp it does. Jaguar has good engineers.
