Hi all in oof land, got a problem and after some oppinions.
I'm pretty sure the thermostat is stuck open as the temp gauge hardly moves, even after a 100+ mile trip the other day ( A and B roads and motorway driving) it only moved about the thickness of the needel, allso the tick over has become eractic hunting between 1000 and 2000. I was thinking the two could be conected as after the motor way run and a bit of heat built up the tick over was ok but buy the time i got home ( back to slow town driving) it had started to hunt again, and yesterday sat on the drive getting anoyed with it I revved it up to the red line and back and it was ok, makes me think that no hot water is getting to the throttle housing and messing up the tick over.
This could all be wrong and I have two separate problems, but may be their connected. Anyone any thoughts on this.
Thanks Tim. :) :)

if you run engine from cold squeeze the thermostat pipe if you feel the water flowing in your hand its open,
-
Top hose get warm quite quickly soon after starting and heat in the cabin is down a bit as well.
-
its open looks like you need a new one, got mine from halfords but cannot remember the price but under £50 as it is the hole thing.
-
Had one quote this morning £20 from a local shop, will try a motor factors later should be able to get it a bit cheaper. Still wondering if changing the stat will sort out the tick over problem.
-
would say so as engine not getting hot enf, that how I know when it had gone, £20 not bad.
-
definately sounds like your stat is goosed, it will sort the erratic running out as the cars ecu is being confused.

The price is from a local car parts shop, who get their parts from a motor factors I think, so may just cut out the middle man, price was for stat and gaskets dont think it included new housing. Will change it as it needs doing and if it sorts out the bad tick over then all well and good if not then i will start swapping stuff, done the crank sensor a few months back changed the icv again( on my third one ) the other day so next may be throttel position sensor, if still not fixed then may think about getting tech2 involved.

if ecotec it is and get new seal.

Will make sure the new one has all relevent bits with it, it is the 2L ecotec motor. Thanks all for the advice and help, next warm day ::) i can drop the coolent and change the stat. :y :y

Don`t need the housing Tim just stat and O-ring. Remove housing, prise O-ring out, twist stat about 90deg (similar to light bulb), re-fit new one. About 20mins. :y
-
Cheers Rob, think it said in the Haynes big book of lies that you need to change the whole thing ::), easy job then, will sort that in the next few days. :y :y

Hardest part is releasing the clip on the small hose @ the housing
