Rear heater matrix

[al & chris]

A few years ago front heater matrix hose on our bongo failed due to very brittle plastic on hose connector. I replaced the heater matrix. Are the hose connection points on the rear matrix as prone to the same deterioration and brittleness. Should I replace rear matrix just as a precaution as I am thinking of doing ?

yes they are plastic, and are known to fail.
if i remember correct alans vehicle services at plymouth does an all metal replacement part that is better than new.
