Hi all, My car has always tended to over heat although this has usually been manageable. Recently in cold weather, I have noticed that the temp gauge seems to go right down, almost to the very bottom, especially at speed, on motorway trips. 
Could this be a stuck thermostat?

Thanks Shell.

It should sit in the middle of the gauge for motorway cruise, being facelift that would be 85, its fairly common for V6 to get a sticking stat. There is a guide in the maint section, if your handy with a set of spanners 

[shell]

I'm no good with spanners. any idea how much it may be for a garage to replace the thermostat?

Thanks again.

Easy way to check the 'stat

Start engine from cold and leave to idle. Stand with one hand on the large top pipe from the engine to the radiator .. the one that comes from the 'stat to the radiator.

This should remain cold and then get a sudden surge of HOT water as the 'stat opens.

If the pipe slowly and gradualy warms up as the engine warms .. the 'stat is stuck open

Phew!!! Back to normal! 

Since when was it normal for a V6 'stat to stick? 
I suppose I'd better change mine then .............. I've never even seen my stat in 7 years

Thanks Entwood, I will try that tomorrow to be sure.

cheers,

Lots! The stat is buried in the the middle of the engine so isn't the 5 min job it is on other cars/engines.

and there are one or two "awkward" bits that can bite and make the job a lot longer ....  The Transfer Pipe and the B*******d Bolt come readily to mind .....  ( I'm SO glad I paid DLK/EP to do mine ...     )

I would also prefer to pay instead of messing with bas***d bolt

Thanks Andy, its probably not a viable repair then, will that do any other damage to the engine? or can I sort of live with it? The car is really on its way out, but don't want to give her up until necessary.

Thanks again.

you will consume more fuel, and cats will face unburnt fuel which can cook them..

Right then you..... 

I've had to do the stat on all 3 of our Omegas, the 2.2's went at approx 100k and 9 years, Mother T's 3.0 Elite failed at about 85k and 9 years

I did say fairly..... 

[shell]

OK, thank you, to all of you, for brilliant help and advice!
This forum has already kept my car going many times, and has saved me a small fortune.
I'm grateful to you all! I guess the writing is on the wall for my old mig, but I will persevere with her for a few miles yet.

Cheers Shell.

I found the job fairly easy to be honest when I did mine. The ba....d bolt was not the ba....d I thought/and was told it would be. Not too bad at all, I couldnt work out what all the fuss was about to be honest.
