The needle of the temperature gauge is always in the blue bit.

I first thought the gauge is not working but it is because it rises when stuck in traffic.

I'm guessing thermostat is stuck open.

What do you think?

dodgy sender, used to happen to my 1.2i, even after cleaning it up it never showed above half (had a broken stat at the time) with the 1.6 in/same clocks it worked perfectly

Yeah.

No, its got the standard 92 deg one.

I'd say check the stat, as it should be getting warmer than that when driving.

Those guages aren't brilliantly accurate or predictable. The best way of seeing if you have a 'lazy' or jammed stat. is to grab the hot hose (careful now ted) or alternatively you can tell from how quickly the heater gives you hot air inside the car.

I have a 1.2 1992 and mine does the same drove from Birmingham to Portsmouth this week and never went over the blue.

when you fit the new stat, you will most like find that the head gasket is knackered too.........

I ran my 1.2 for about 3 years with a stuck stat... was always fine

if tis always cold, its stuck open. Therefore the HG should be fine.

Why is that? :confused:

you have to ask yourself, why did someone take the old one out & not replace it with a new one that would cost less than a fiver.............its always to mask a head gasket problem, the car doesn't get warm enough for the gasket to leak... its one of the oldest bodges in motoring

I know the car's history, I didn't just buy it of a randomer.

Plus there are no signs of headgasket issues.

stick a stat in it, and you'll soon find out, it was taken out for a reason

Why Ad? Mines seem to run fine with it in..

Adam

The engine runs fine, but its running too cold.....
It should be running warmer hence why it comes with a 92deg stat originally....

Mazz
15-04-10, 03:51 PM
Might try the original stat then..

mowgli
15-04-10, 03:52 PM
