temp issues......help!!

[punkrockscreech]

Hello peeps, I'v a 91 rev 2.0 N/A. Iv been using the car a fair bit recently (trying to replace the daily.....don't ask!!!!) driving the car back from work earlier i noticed that it didn't come up to temp then as i drove further it very slowly began to drop even more, by the time I was home it was almost at nothing!!!!

This morning it was fine and the heater still works fine!!

Any ideas chaps?
Many thanks
Steve.

Sounds like faulty temp sensor, air lock in the system or thermostat is stuck!

Maybe try bleeding the system first?

I fiddled with the heater control to bring hot air into the cabin, this got the gauge to drop then when I slid the control down to cold the gauge rose a little but then slowly dropped as I progressed home.

Cheers

My bet is the thermostat! easy job to replace it.

[punkrockscreech]

Hopefully, although I replaced it only about 2 years ago.

Bloody cars!
Cheers

Did you use forlife coolant?

[punkrockscreech]

No, I know she needs good quality stuff so sourced an equivalent alternative. That said though it wasn't on O/E thermostat?

You can easily change thermostat and use coolant every time.

Is it safe to drive the car with a low engine temp?
