Losing Coolant

[Parkerwarne1]

Please can someone help!

I have had my head gasket changed and the problem is still the same! When the car is driven I lose coolant through the expansion tank which points to head gasket or possible crack but when the car is returned and idles there is no loss of water and also the engine is not overheating until the tank is empty which is after about 100 miles. All the usual has been changed thermostat, pump, etc. Now the expansion tank does show a combustion leakage but I dont understand how on idle there is no problem only when driving! The EGR valve has been mention as it is water cooled is this possible? Any help welcome.

Many thanks

This is possible the EGR cooler can leak into the exhaust system

I had a problem early on with mine where one of the little expansion pipes back to header had got a pin prick in it and was spraying over the front of the engine. I did not notice till temp gauge went off the scale. Turned out the leak was caused by the pipe becomming unclipped and rubbing on the AC pipe just to the left front of the engine above the radiator.

 

The EGR cooler could be the problem athough it is all out of stainless steel so I would supprised. I have one on ebay but not sure if it would fit. Pretty easy to fit.
