Right just a word of warning here as i changed my thermostat less than 2500 miles ago as the original one wasnt closing fully so i bought one from eurocarparts. It look perfectly good in comparrisson to the original one removed and was half the price of an OEM one from the stealers.
So changed it and its been fine until a couple of days ago the car wouldnt get up to 90 degrees it would try and then fall back down. Now its not even moving off the 60 degree mark at all. I had scanned the car so was pretty sure it wasnt the engine temp sensor so i bit the bullet and bought an OEM thermostat and o ring from the stealers for £26 and went to work changing it over.
I got the ECP stat out of the car and can instantly see the problem was the the locator pin that holds the stat central was out of the hole it sits in and therefore could not close properly.
So new OEM stat is in along with G12 and the car is now sitting at 90 degrees again.
So will be taking the faulty stat back to ECP for a refund along with the 5 lires of G12 i bought from them and i shall also try to get something out of them for the time wasted in fitting another stat within 2500 miles.
