Got a Thermostat problem!
« on: 08 March 2007, 17:35:46 »
Or should I say "Had" a thermostat problem.

I've now changed my thermostat for a nice shiny new one. Yet to test it, but I'm sure it will help all round. I will post results here, when I've driven it a bit.

The new stat was definately needed....... can anyone hazard a guess, at what I saw when I took the old stat assembly off?

As near as it gets, yeah.

Some bodger had completely removed the thermostat from the housing, so there was just a gaping hole! No wonder it wasn't warming up.....

Not had chance for a road test since changing it.. but...

Chances of this improving my MPG?

Quite a bit I'd say. The ECU won't now think that the car is constantly warming up (bit like having the choke on).

Why do you think it had been ripped out in the first place, is the rest of the cooling system in order?

I guess you spotted the taletell signs of a thermostat stuck open (or not one there in your case  :o ) :y

And for anyone else reading who's not sure......taking a long time to warm up and temp dropping down to 70-75ish or less when on a run.....is a good sign thermostat is stuck open  :y

Yes James....a working stat will definately help your mpg  :y

Possibly the previous water pump was duff or the radiator was a bit clogged
