Coolant Flush, Hot Engine, Cold Water?
Trying to plan the cooling system flush I'm going to do in a bit and I got thinking about many coffee pots being broken by being hot and having cold water put in them.
It's winter here, and below freezing, I have some stuff to do before I can flush my ghastly cooling system, so I won't be able to do it with a totally cold engine.
I have some chemical cleaner that says safe for all cooling system metals that requires driving around a bit with the cleaner/water mix.
After that I want to put the flush kit on and back flush my heater core and cooling system before finally filling with coolant and distilled water.
Is there a concern with the cold water from the hose going into the hot or warm engine for a flush? I'm going to install the flush kit "T" on the heater core outlet, but where should I drain the water from??
I know to backflush the heater core alone it needs to be disconnected, but for everything else what is the best way to get the water running out so it cleans out every nook and cranny?? Bottom rad hose? The hose from the bottom of the reservoir?
Rest In Peace Mom.
