Temp Gauge
« on: 04 December 2007, 01:35 »
The temp gauge on my car is usually on 90 when the engine is warm, but the last couple of days it will warm up to 90 and then when i start to drive it will start dipping and go right to the bottom. If i leave the car started without driving it will go back up.

Anyone had similar problems or got any idea what it could be? Really hope its not a big job its the last thing i need with xmas just around the corner :sad:

Well guys just been down to my uncles garage and he got the mechanic to have a look at the prob. The guy said my a/c is on and that will be the cause of the problem, i said i havent even got an a/c button and its so damn cold so why would i have it on. Anyway my uncle pressed the 'Econ' button whilst the mechanic was looking at the a/c pump under the bonnet and when he switched it on the a/c pump went off. So he said try that for a while and it should be ok. Ive drove it around and it seems fine.

Firstly i dint even know i had a/c and secondly what the hell is all that about!!!!^^^

the early ones didn't (as standard) i think it was standard after 2001

the A/C doesn't explain the coolant temp though, i know the A/C uses that temp sensor but it should be one way and having the A/C on shouldn't cause the temp reading on the dash to be wrong
