Default Flushing the cooling system..

How do you do it? I couldn't find my petcocks, got a little lazy, and pulled out the shop-vac. Sucked the coolant right out the radiator. I had the T-stat housing off, so I watched it all drain out. Plus I poured water down in the area where the T-stat goes, and it cleaned it out all the more. My shop vac was semi clean [some dust and other crap found in my interior/carpet], and when I poured the water out, it was brown. I was incredibly happy getting all the crap out. I wish I did it sooner. That, and I wish my housing would seal, so I could put some more water in to flush it out again and see if it leaks!! Damn waiting times! Oh yeah, if doing this method, if you don't have your housing off, remove the hose which connects the housing to the top of the radiator, otherwise you'll kill your shop vac .

Remove your thermostat, and re-attach the housing. Disconnect the lower radiator hose, and put a bucket under the outlet of the radiator.

Start the car with a garden hose stuffed into the outlet hose on the engine side. Use a rag to keep the water flowing the right direction. Stop when the water is clean.

This will get it all, and completely flush the system. Dispose of old coolant in the proper manner. Most gas stations or wreckers will dispose of it for a small fee.

Re-fill with a 50/50 mix.

Wow, that'* what I wanted to do with the petcocks.

I'm confused about the garden hose stuffing. Do I put the garden hose on the tstat or radiator side? Or do I put it on the lower radiator hose?

In the lower hose. Squirting into the hose up to the water pump.
