Help Needed Please

[Tony5496]

Hi can someone help me please I have a Ford Galaxy 1.9 TDI on a x reg. about three months ago had the Cambell changed ever since it has massively high pressure in the expansion bottle even when the vehicle is cold in the mornings. Would are big airlock do this ? as well I have also lost the rear heater in the rear of the car it blows cold as well. Today when my wife come home I noticed a puddle of antifreeze under the car I've had a look and it looks like it's coming out of the expansion bottle and boiled over. The temperature has stayed at 90 but my wife did say the heater was blowing hot and cold could this be the water pump on the car playing up any help would be much appreciated thank you very much tony

Sheared water pump impellers can cause overheating when under load but I suspect you now have head gasket failure

Hi Tony,

 

How'd you get up to 90 in this weather! There are 2 water pumps, the main enginge one and an extra one to pump coolant to the auxiliary heater in the back. You should hear the aux pump running for a few minutes after turning off the ignition, if there's no sound then the brushes are probably worn away to nothing and need replaced (or replace the whole unit, which is a bit easier but more expensive - see thread in the FAQ). I'm presuming the other water pump was done when the cambelt was changed and so should be fine. Have you had a feel of the hoses to and from the radiator to check if they're both hot (thermostat)?

Just saw Chris's post, what I would say is I did have problems with boil-over when I'd been messing around with the coolant system to fix the aux heater, this is since settled down probably due to having a now working aux heater, and aux heater pump.
