GivemeaVR 0 Posted June 14, 2007 The car has suddenly started taking ages to warm up. By the time i get to work which takes about 15 mins the water temp is only on 70 and the oil temp is on about 80. Does this sound about right as it used to be at running temp of about 90 by the time i got to work. Any ideas what it could be? Thanks in advance.

flyferrari 0 Posted June 14, 2007 That IMHO sounds like a thermostat that is stuck fully open i.e. the coolant is running through the rad from start-up. This will cause increased wear on the engine over time due to the fluids taking a long time to get to operating temps at each start from cold. I'm going to have my thermostat changed by The Phirm soon. I have the opposite problem....mine doesn't open far enough. Tim said about 30 mins to change plus parts....not the end of the world.

GivemeaVR 0 Posted June 14, 2007 Should the water temp be higher than the oil temp as the engine is warming up? Quote Share this post Link to post Share on other sites
double-6s 0 Posted June 15, 2007 I think the water temp should rise quicker than the oil temp. Mine does anyway. Quote Share this post Link to post Share on other sites
GivemeaVR 0 Posted June 15, 2007 Ive ordered a new thermostat from V.W today. I cant think of anything else it could be. Can anybody tell me where it is on the engine? Thanks Quote Share this post Link to post Share on other sites
Supercharged 2 Posted June 15, 2007 It's on the right hand side of the block as you look at it in a plastic housing (which you will also need) which holds the temp senders (ideally change these too) Quote Share this post Link to post Share on other sites
