Ive been away awhile,and everything has been good with my 00 D2. About a week ago I was driving to work and noticed the primitave temp gauge rise enough that i was concerned, then as quickly as it rose it went back down to normal range(right in the middle) and no i dont have an ultra gauge. its happened a couple times since then, and what im wondering is if the thermostat isnt opening when its supposed to causing it to start to over heat? Anybody else had similar problems? And is there anywhere to get all the coolant hoses for a decent price? Ive checkedwith british atlantic and $300 seems kinda high. Anybody with thoughts please post.
