Helpful Tip:
When replacing the heater hoses at the rear of the engine, replace the o-rings for the nipple flanges that the hoses connect to. One at the rear of the block, the other at the rear of the cylinder head. They deteriorate with time, especially if the engine has seen overheat conditions and/or oil into the coolant.
They are standard size metric o-rings. I replaced mine from a common nitrile o-ring assortment set .
