Ways to blow the water out of PCM motor

[sjames]

Has anyone come up with a good method to blow the water out of the PCM motors? I pulled the heater line off of mine and used compressed air which seemed to get some water out, but probably not all.

You don't need to, use the drain plugs and let gravity do it's thing.

Light compressed air only for the heater with both lines disconnected. Lung power is adequate.

I put a funnel in one heater hose and poured antifreeze in untill it came out the other hose.

Any pictorials showing all the drain plug locations? Was hoping to not crawl down in the V drive coffin.

There are plugs on each side of the block below the exhaust and spark plugs. on a Chevy, one may have the knock sensor in it. There two on the exhaust risers, these are big and brass on the ends. Also, take the hose off the transmission cooler. If you have a shower, you will want to drain that too. As for the heater, you can lightly blow that out, or do what NautiqueHunter mentioned above. This is easy, cheap insurance.
