i disconnect my matrix today and put a hose pipe in to one side off it and turned hose on, and after few min's it started to flow out the other side so reconnected it and still the same.

looks like i will have too take it out again ??

do you have to take the dash board out to get to it ???

and been told to soak it in some drain cleaner would that work ?? or shall i just buy a new one ??

thanks for you help
