Overheating
Hi all,
On Thursday night I was driving home and my heaters went cold. I thought that I had ran out of water, so after driving into the petrol station I checked it and it was full. The top pipe of the rad was hot and the bottom one was stone cold. I squeezed the pipes and then left the petrol station and headed for home which was about 5 mins away. The heaters came back luke warm for about 30 seconds and then went cold again and the gauge started to rise up past the normal running temp. I left it parked up for the weekend and this morning had to attempt to get to work and garage, ( garage is next to work ). On the way to work the heaters were stone cold and the gauge went up about 3/4 of the scale. The garage picked the car up and immediately thought the waterpump or thermostat was gone. They rang me up to say that the pump visually is fine and they put the stat in a kettle of water appears fine. They are fitting the new pump and stat anyway as its in bits.
does anyone have any ideas what this may be
The Radiator Fan does not come on
The heaters are cold ( matrix is newish )
Radiator is newish about 18 months old ( top pipe hot, bottom cold )
Water level is down in the bottle by about half
I was thinking maybe the head gasket is shot, the garage think this may be the case but it doesn't explain the cold heaters and they said blockages don't usually just happen its gradual over time
the car is a 2.0 8V code 3A cheers
