yoo guys,,
ok i keep springing a leak from the heater matirx,,,,ive had it out from the car twice (dashboad removal)
basically where the plastic end tanks are glued on,,,it leaks out of a tiny crack,, iive tried to glue and now ive tried fibre glass resin,,,but after a couple of weeks its leaking again..

there must be a glue or some way of repairing as the crack is so small,,,
any ideas,,,,or do i buy a new one from mazda?

 

why would you not put a new core in it? that is a **** load of work to do 3 times.

 

tell me about it,,,i can take dash out in 20 mins now,,,, but i live in the UK and mazda parts are expensive

 

just get a new one and be done with it. ever seen a canyon? water always wins its just a matter of time. i would not trust any epoxy

 

i agree with mad 7
