Yes the blazer is back on the road, no smell of antifreeze, no steamy windows, much lighter wallet. Price of heater radiator was pretty good, cost of fitting it ..............! Garages over here never see these so 15 hours labour. They did give me a bit of a discount though and glad I didn't try doing it myself.

It can be a PITA to replace the heater core, my son's friend just paid $60 for a new core and 3 nights work to install it.
