How do I flush the heater matrix?

[RobbieL]

Hi,

I have a 2000 Bora and the air con doesn't get any more than mildy warm. I have bought a solution to flush the matrix as I've read they regularly get blocked. My Q is, how do I do this as I understood the ehater matrix was a dash off job to gain access?

Cheers for the advice mate but as I've bought this stuff now I'd like to try it all the same. how do I do it?

Hi I take it you will try this without removing the matrix? You remove the 2 coolant hoses which are attached to the matrix at the bulkhead.You will then need to drain the matrix,with a bit of air pressure.I dont know what sort of flush you have,so you will have to take from here
