Rapid Loss Of Coolant In C3 (2002)

[Guest Lars]

Our C3 (2002) has an ongoing problem of using coolant at a rapid rate. There is no obvious external leak we can see.

Any advice on what the problem is and likely cost to fix?

 

Thanks in advance,

If there are no obvious external leaks (radiator, all hoses, air bleed cap on rear hose, water pump seal, filling cap poor seal, cabin heater matrix) then this leaves the engine cylinder head gasket may have failed - you may see steam coming out of the exhaust if it is really bad and water in the engine oil. A garage can check for exhaust gases in the header tank which will help confirm gasket failure. If it is the head gasket then you would be better not using the car until fixed in case the head becomes warped which will increase repair costs - this could happen anyway if the water level is too low and allows overheating.

 

You have not mentioned it going to high temperature so I have assumed the cooling fan is working and the water is not simply being boiled off like a kettle out of the filler cap.

 

A web site like eurocarparts will give you some idea of the parts cost if doing your own repairs. If you provide your engine model somebody here may give you an idea of a dealer repair cost.
