Hi I have a coolant leakage on the joint between the heater matrix inlet on the bulkhead inside the bonnet and the pipe. It drips when the engine is cool and stops when it warms up. Now am at loss which one to replace. The matrix is new having replaced it last year and the pipe still looks new and last week I fitted new o ring seals.

Problem solved. The matrix was of non genuine quality and and there was an issue with the sealing between the O - ring seal of the hoses and the matrix joint on the inner side. A genuine Valeo matrix did the trick and no more leakage
