Heater Matrix problem

[monkeyinmyhead]

Hey all, Just swapped over the heater matrix using a very handy guide sourced from these hallowed pages but without success, followed it to the letter and still no heat coming through.

Any ideas?

do you have bypass valves fitted

what Mk golf is it ?

Its a mark 2 mate, not unlike the one in your signature actually! Im not sure, the guide didnt mention any, I just followed the instructions and swapped em over. Thanks for taking the time to reply.

2 valves in the pipework in the engine bay, one silver / metal the other black / plastic .

they can cause no HEAT, i swapped mine but they are getting like rocking horse doo dah.

if it a new matrix you CAN remove these, do a search, loads of info about it

I think eurocarparts still do the pressure relief - but you shouldnt need to fit then if you have fitted a decent quality new matrix  (relief valved fitted as part of a recall as some Mk2 matrix's (matrices ?) burst spraying occupants with steam - idea being valve would prevent injury).
