Does anyone know of a way to flush most of the coolant from the engine block using compressed air? I stripped the drain plug head an will likely not be able to remove it from the engine block. Thanks for any input.

Sounds like a bad idea to me.. there are plenty of ways to get a stripped plug out.

Agreed... its not like you are going to strip it anymore... I'd much rather Macgyver some stuff up then use compressed air in my engine... much less potential for disaster

macgyver it! compressed air inside a block = BAAAAD THINGS

You wont hurt anything using compressed air. Just take off both of your coolant lines from the heater core, and get an air gun, stick it in one hose, seal it off somehow, and blow the coolant out the other hose.

Not sure how well it will work though. I would go ahead and try to get the drain plug out and flush it with a garden hose.

just take off both hoses, upper and lower, use a garden hose with the upper inlet and flush it this way, its all you need to do, dont use air, just because it will be a pain in the A to get all the air out of the system, wont damage anything, just alot more work then need be.

I dunno about the compressed air idea. Blasting around 100 psi (or even 50 psi) through things that were never meant for that kind of pressure (even with everything uncorked) is kinda looking for trouble. What you need is volume, not pressure. Try using a shop vac and gradually place the nozzle up to the chosen opening. Use pressure if at the top of the motor, vacuum if at the bottom.

You do not need compressed air - just volume - use a little blower. Try using the blower function on a shop vac.
