hi all, ive had a good read through lots of threads about engine temp issues. and it seems the thermostat is just as common as the temp sensor. but i cant quite fiqure out what my issue is, so here goes... driving this morning, i did approx 20 miles, got home from the misses place and noticed my engine temp wasnt quite at 90. was about 86. so i decided to go back out and try and get it to 90 as ive never had this before usually up to temp within minutes. was driving like an arse at high revs and it wouldnt budge. then sat at traffic lights and it dropped to about 83 ish. then when i pulled away it rose to about the same 86-87. and thats as far as it went. do you reckon its the sensor? or thermostat? im going to take it for a blast to the jet wash later...see if it rises to full temp. im hoping it isnt the thermostat as i have read its a right pain to do, a job that involves alot of swearing and tool chucking?
