Default Coolant flush... remove t-stat?

This seems like the easiest way. Then I don't have to wait for the damn thing to heat up just to circulate the water and whatever cleaning agent I put in. And wait for it to cool down to get back under the hood.

No need to lift the car to get at the knock sensors. I can even run the garden hose through the system to flush it, with no tstat.

What do you guys think? Am I missing anything?

I've always removed the stat and run the car up to operating temp with the first flush, then backflush with the car off for the second flush. Then flush the cleaner out with the engine running.

Me, too, although I don't let it get above about 160 degrees - makes it too hard to work on. Seems to clean out ok at that temp.

I've always let the highly trained technicians at Jiffy Lube handle mine. Then I fix the broken outlets on the radiator

did they use an impact wrench to put it on?

The thermostat is so easy to remove on these cars, it doesn't make sense to not remove it. Actually, the coolant flush and fill procedure on these cars is pretty easy, other than having to remove the knock sensors to totally drain the block.

Yeah, I'll do that last, before filling up, just to get all the hose water out.

Keep thermo IN (Maybe just put a new lower temp one in it's place) There are heaps of tech data around to reference this with - I suggest u find them.
