right, so i tackled the heater matrix today with the lord's guide, not a bad job at all to get out (with the guide ) apart from a screwdriver incident:
(the pic doesn't do it justice )
then with the old one out and the new one unboxed i started prepping it to go into the car, but when i went to pop the new rubber seal on the new matrix, this happened:
the plastic backing thing snapped off (new one on the left, old on the right)
is it still ok to use? the pipes have a lip on them which stops the seal going over them, but should the rubber seal go past that lip, right up to the matrix?
this pic explains it better:
then which seal should i use on the bulkhead? the old (on the right) or the new (the left)? the new one is just a piece of sponge with some paper like stuff on it, doesn't seem like it'd seal very well?
cheers for the hep in advance ;)
