My A14 temprementally overheats i can drive it hard all night and no worries but then the next night it decides to overheat...

its got me stuffed whats happening cause it wouldn't do it when i had it sitting on about 6grand all the way up throught the mouintains, but it did the next night when i was taking it easy..


any ideas?

First check fan belt tension then check for a sticking thermostat by putting it a pot of boiling water. The thermostat should open smoothly when the ater gets above the set temp for the stat.

If it looks a bit sticky pif it and get a new one as they are cheap.

If the ambient temp is the same for both instances then I would be checking the thermostat to see if it is faulty. It may not have one though as I have had 3 A series here in Aussie and all had the thermos removed when I got them. If your radiator is in good shape then you may have impellor probs on your water pump. I'm running a 3 core on my A 14 and the thermo fan rarely comes even though I'm now running a thermostat so standard set up shouldn't give you any troubles.
