So I'm coming up on a maintenance weekend, and want to include a coolant flush and replacement along with it for a couple of reasons. One, being to clean out my coolant reservoir of all the gunk that the dealer didn't clean out when they replaced the LIM gasket and elbows. It makes it a real PITA to see how much fluid I have in there. Two, I've got the water in the dash sound and understand this to mean there is air in the system. I've read that I have to "burp" the system, but am not 100% certain of the procedure. I understand there is a burping screw or something on the thermostat housing, but want to make sure I don't get sprayed with 200 degree coolant while im doing this.

Hopefully getting there soon with all my maintenance work. I've been stockpiling supplies to do it all in one weekend. New accessory belt, SC belt, SC oil, thermostat, plugs, wires, seafoam and seafoam deep creep, new oil filter with 5 quarts of castrol edge full synthetic 5w30, cabin air filter, and a surprise. The only thing I think I left off my list was a transmission filter with gasket, and tranny fluid. Im a little timid to do that. I've never messed with a tranny before, other than replacing a clutch in an old 4 speed Toyota truck.

On my 3800 to get the air out of the system I've always left the bleeder screw loose, filled the radiator up, started the car and added coolant until it wouldn't take anymore. I then put the cap on, made sure there was coolant in the overflow bottle and let it run until coolant started coming out of the little bleeder screw. Tightened it up and have never had an issue with "burping" or that sloshing sound people complain about in the dash.

Cool deal. What about flushing the system? I've seen a couple of different methods after searching, but not sure which is the best. I've also read not to use the prestone flush stuff in GM cars, but can't find anything to back that up.

You can remove the drain c**k from the radiator and flush water through the radiator, or you can remove the knock sensors and flush water through the block too.

Typically I just use the radiator drain c**k, remove as much fluid as I can, then fill with water, then run it through the car for a little bit, then flush through the radiator, and repeat until it is clear.

Then I fill back up with as close to a 50/50 that I can.

Take it to a shop. So much easier. $75, one hour and all new coolant
