Hi All,
I’m flushing the cooling system on a 322. What I’ve been doing is just draining the system from the pet cock on the radiator but seems like this only gets about 2/3 of the fluid out. Is there another way or better way to get everything out. I used restore and I’m worried about leaving some of it in the system and it causing corrosion. I’m also concerned that having 1/3 of the system as water will dilute the premixed anti-freeze to much.

Haven't done this to mine yet...but will follow the method Dad taught me: treat engine block and rad separately, remove rad hoses and flush each on its own until the flush-ate is clean/satisfactory, then replumb and refill the system.

Theres a block drain plug on the engine.
I think it's close to the oil filter, if I remember right. That will drain most of the block.

Its sounds like your radiator might be partially clogged. I would take out the radiator and have it pressure test & flushed out. Also flush out motor block-with distilled water only. I don’t know much about the 322 but the 332 had a valve on the motor block to flush out the rust and contaminants over time.
