My wifes Disco has been overheating sometimes lately. The coolant levels are correct. She rang me on the way to work today saying it was doing it again and I said to turn the heater on which helped and brought it back to normal. She was driving with the Aircon on and was on the highway.

Now I dont know where to start in looking at why its doing it. I am thinking maybe putting a new thermostat into it?

She I maybe get the heads checked?

Any help appreciated, its our only car.

Howdy, my first thought would be blocked radiator.
Pull it out, take it to a radiator man and get it rodded.
I've been through this myself, and found that to be the problem, also it's one of the easiest and cheapest fixes to try first up. Should cost around $100 with the radiator out of the car.

I would check to see if your fans are working properly.I have had similar symptoms with viscous coupling fan on more than one occasion.For the price i would change the thermostat to be sure.Then try radiator and get heads checked.Good luck with it

You could stop it with a screwdriver very easily:eek:.They have thermo's for the a/c.
I have tried thermo's but have been nothing but trouble for me.:mad:

how do you stop a thermo with a screw driver? does that mean its not spinning fast enough?
