its hard to explain so bear with me......

when starting the car from cold and driving it, after about 5 miles the temp gauge shoots up to about the N, and then goes straight back down again

The heaters also do the same thing though, when the temp gauge goes right up the heaters are nice and hot, but once the temp goes back down the heaters are lukewarm

only seems to do it on say a 10mile journey, doesnt tend to do it on short runs

any ideas?

 

thermostat probs?

blocked heater matrix?

 

wont build up much heat on short rides.....shity old fords.....lol

 

airlock in the coolant system?

 

shut up chocolate box

 

r u refering to my arse....

 

no

 

any other ideas

 

Sounds like an airlock in the heater matrix

 

if there was an airlock wouldnt it overheat?

 

i'd suggest a sticky thermostat!

 

ill try a new thermostat tomorrow and see it that helps

 

Yeah, sounds like thermostat. It goes up high until the thermostat eventually opens then it plumets back down again.

 

I can just see the post title tommorrow..

" Help just sheared my thermostat housing bolts" !!
