My Omega doesn't normally get much day to day use, but it has been over the last couple of weeks. On my way to work yesterday, after about 10 miles of stop start driving I noticed that the engine temp had managed to reach a heady 90oC - normall sits at 95 ie halfway round the gauge. I tried to get the temp up by dring it a bit harder on the lanes nearer work but could only get it to go up another couple of degrees and even then the gauge went back down again as I actually got to work.
New thermostat ordered yesterday.

The way the weather is here I think it'll be more like spring or summer before I get the chance! ??? ???

Over the last couple of weeks mine has struggled to get past 85 on temp gauge. :(. It won't be getting touched until the fairer weather. I've got a garage on the side of my house but it is full of the usual bits and bobs and a motorbike so I can't get in it to work on the car. :( ::)

V6 stats tend, with age, to start sticking slightly open, causing cool running on a cruise, that goes up to normal temp (midpoint, so 95C for prefacelifts, 90C for facelifts).
Replacement, as you suspected, is the cure. Not too bad a job, but a bit fiddly the first time you do one.

It's not done bad. I've not changed it in 8 yrs/80k miles so suspect it's the original ;) ;)

just clocked 90,000 on mine and no record of it ever being done,so i think mines original stat too. ;)

I've done 80k miles, but the car has just turned 173k :y :y :y

Anyone know the price of the stat these days ? Is it a TC item ? :-\

I'll let you know when it arrives from the Father Land :y

..... Is it a TC item ? :-\
Just looked at the TC site, couldn't find mention of the 'stat though. :-\ :-\
-
If just stat being changed, 4-pots are the same & cheaper

i had quote from my local stealers of £57.44 that includes stat with housing & 3 seals HTH. ;)

So I believe, but when I helped Ian_D with his head gasket I looked at his 'stat (the 1st time I've seen one) and although I only gave it a quick coat of looking at (cos it had to go back into Ian's car) I couldn't see how the actually working bit came out of the housing. :-\

Press it in and twist...its a bayonet style fitting ;)

OK. I didn't want to play too much, just in case I fixed it beyond repair! ;D ;D

Last one I bought was arounf £55 with the 3 o rings

It took a week for the back of my hand to heal after the last time I changed a thermostat - that was on her Smart - the (single) temp sender is part of the assembly, but a similar price IIRC. Once the B bolt has been tackled, the Omega's will be a walk in the park. :y :y

if just want the stat quinton hazell do one for a £10, the reason i state qh is some of the brands dont have the correct taper to fit the end. ( i didnt want to buy a housing)

I took the easiest but most expensive option of ordering it from my local dealer so didn't do any homework. Thanks for the info though. :y :y
-
So, its possible to buy a stat without the housing ? :-\
-
part no QTH600K 92 degree.
although, seems cooler. then again its not exactly warm air going thru the rad at the mo :o

Yep, that's what I did when I replaced mine, while replacing head gaskets. Got a QH one off fleabay for a few quid. :y
-
Just bought a QH one for the TD from CAF, £10 odd and included the seal!

Mine was £51.72 including a 'stat housing to block seal & 2 O rings for the housing to tube seal. Oh well! C'est la vie! ;) ;)
-
How the Flying *@*! are you supposed to get the thermostat housing to part company with the ally pipe that then connects to the top radiator hose??? >:(
I guess that the dealer that did the head gasket before I bought the car swapped a spring hose clip for the Jubilee hose clip that's there now & put the 3 washers behind the head of the b'stard bolt ;)
-
Leave the bastard bolt in, remove the 2 thermostat housing bolts and waggle the housing with a mole wrench until it breaks the seal with the transfer pipe, then remove the bastard bolt, as shown in the video. :y

Not a chance! Tried waggling & wiggling from either end. It's out now after I got nasty with the 'stat housing! I could just get a windy recip saw in to cut the end off. Even in the vice the chopped off end needed 'help' with saw lines down its length. I'm glad I bought the whole thing now. ;) ;)

All done & dusted.
EML on when finished & for some strange reason TC light ???. Then plugged IACV in & throttle postion switch ::) ::) EML still on ??? ??? Then plugged EGR valve in and all lights off. ::) ::) ::) ::) I was cold & wanted to get in the house ............. ;D ;D ;D ;D
That's very definitely the 1st & last V6 thermostat I ever fit, by comparison, my diseasal Astra's 'stat took 10 mins from start to finish.

Agreed. It's a PITA. Especially when you find it leaking 2 weeks later, although that was down to a pattern water pump fitted at the same time. :-X

Ouch! I've got to do my 3.2 sometime this year, just waiting to do the TD first as they've both got to be done. Maybe I'll pay one of the experts on here to do the V6 just to learn how to do it properly :D :D :D :y

If it's any consolation, the b'stard bolt is more of a PITA bolt, not as bad as its reputation. ;) ;) ;) ;)

I do admit that even though it took me half a dozen attempts to get a start on it, when it did, it started fairly easily. :y :y :y

Anyone know the procedure for removing/ replacing the old stat from the housing if using a pattern stat rather then VX complete with housing ?
I have a spare one complete with link pipe I can play with.

The 'stat itself just pushes in a little, turn it & then it'll come out of the housing. But if yours is anything like mine was, you'll struggle removing the 'stat housing from the transfer pipe, I ended up sawing through the end of the housing so I could remove the pipe. I'd bought the whole thing so could sacrifice the old one.
If my camera hadn't died I could'e photo'd it for you. :(
