Right fellas fitted new stat and flushed the heater matrix dropped the water out of the rad and flushed that out too. They have been backed flushed....Refilled with water and run the car the heaters started to get so that was great took it round the block heaters o.k and then went cold...Got back they went warm and thencold again seemed to get hot as i rev'ed it abit but i'm lost have tryed to see if there is an air lock by unsrewing the bottle cap...The fan's are kicking in at the right temp and the car temp is sitting around 90 .. 95 ish....I'm getting fed up now had no car for 2 weeks having to wait for part and now this rather thing.......

Quick update the fan is kicking in at 92.5 and the temp is sitting at 90...The heaters are luke warm on position 4 and warm in position 2 and it defo gets hotter when i rev it what ever posiotion its in....Oh and i have not added the coolant yet does anyone thick that has anything to do with it ?

Could it be a vacuum problem on the HBV or elsewhere behind the dash?  :-/  :-/  :-/ :-/

What engine is it? also the condition of the HBV like?

[Andy B]

What engine is it? also ......

A proper one IIRC

When you flushed the heater matrix, did you flush it both ways? It sounds like a restricted flow of water through the matrix to me, especially since you say the heat improves with reving the engine (water pump turns faster = greater flow pressure of water through the matrix) HTH

Its a 3.0L v6 but a 1995 year and the temp is defo at 90 and the fan came on at 92.5....I replaced the heater bypass about a year ago....and i'm sure the temp as always sat around this amrk but then again not sure i ever gave it that much notice so could be wrong.....

Hi Andy  ...I will have a look tomorrow at the h.b.v i did check everthing when i was rebuilding.  Not sure about behind the dash as i have not been anywere near there.

You mean there's no water in the cooling system or you've simply not added antifreeze? :-?

Not adding antifreeze should make no difference to the way the engine runs - not adding any water will!!!

Get it up to temp and pull the vacuum hose off the HBV, see if it gets hot then.

[tunnie]

'95 3.0 fans should come on at 96, not 92 should they not?  :-/

Will do lee i'l give anything a go at this stage.  Sorry to sound dumb but if it gets hot without the vac hose on does that mean that the h.b.v is up the duff mate. :-/ :-/

Not sure tunnie mate but don't ever remember the temp going that high when all was o.k.
