James,

Yes I did feel some heat on the run but it wasn't very hot, not like it normally should be if that makes sense?

Does everything still point to a stuck theromstat?

Cheers,

Paul

Hi Pete,

Update   -

I tried what you suggested and yes the temp gauge does rise nicely to 85c without the heating on. As soon as I switch the heating on the temp gauge slowly drops to zero.

Cheers as always,

Paul

You'll need a new thermostat Paul. I've had quite a few of these and they've been good

Agree with Pete - I always factor the cost of a new transfer pipe and O rings too - and of course, 5 litres of fresh coolant

Worth doing. You'll get better fuel economy with a working stat

Cheers Pete / James,

I've managed to source one from Twiglet so I will be looking to get this replaced as soon as possible.......

Thanks Guys

A used stat?

[PAULCDX]

Yes I believe so mate, is this not a good idea???

Have sent you a PM re other work

[Elite Pete]

For the price of them Paul and the amount of work it takes to fit I personally would fit a new one

[PAULCDX]

Thanks for the reply Pete,

I believe he has already took one of a car tho, and he is ready to post to me..........

I sent a PM saying the same youth.
Althoughthat is nothing against Twiglet as he is a decent guy.

Couldn't agree more Daz

[PAULCDX]

Ok Guy's

I appreciate the advice,

So shall I source a new one then instead? I'm sure Twiglet won't mind? I will send him a PM..

Pete,

Thanks for the ebay link, I will look into purchasing this one as recommended?

Cheers,

One thing to watch is the new stat housing mountings are thinner than the old ones, so the fixing bolts are too long, and if you keep tightening them up, (a) the housing won't seal, (b) something may crack or the thread strip. You need shorter bolts or a spacer to fit underneath the existing ones.

Easiest way to check a thermostat ...

Start engine from cold (preferably overnight)
Leave idling with air con / heating OFF
Stand with bonnet open and one hand on the BIG pipe from the thermostat to the top of the radiator.
The pipe should remain cold until a SUDDEN surge of heat as the thermostat opens - if the pipe very slowly warms up then the thermostat is stuck open.

This procedure will check that the thermostat only opens once a temperature is reached .. but does not check the actual temperature, however that is normally pretty obvious if it is wrong !!

HTH

Thanks for all the replies and advice guys.

I've ordered a new thermostat anyway and will update soon.......

Cheers,
