Need a new thermostat??

[red harry]

How can I tell if thermostat is knackered.

Have just had a new radiator and rad cap fitted, still bleeding a bit of air out now and then ( am aware that they are a bugger for air locks)

Tried again today: heaters on hot, undone rad cap, not a lot of coolant under it. So started engine , topped up coolant little by little.
Just as operating temp is reached coolant is steaming a bit (assuming this is normal?) I put on rad cap and I am sure I noticed a little steam around thermostat housing.
Feeling a bit paranoid about it all, having already forked out for a new head this year already.

Would appreciate any input/help!

My advice is don't mess about testing the thermostat, for what they cost put a new one in then you know its right

If you click on the forum jump link then you scroll down to the maintenance & repair section there is some information on "burping" the cooling system, which might help you get rid of all those air bubbles.

You can "test" it by putting it in to a pan of water and heat it up
on the cooker,you should see it open when hot.
The only problem there is that you won't know what the temp is ?

As Gary says for the small cost put a new one in and keep the old
one as a spare?


Good luck m8ty Poppy
