View Full Version : Question about coolant flush
11-05-2006, 09:16 AM
I searched and couldnt find exactly what Im looking for. Im going to flush my coolant cause I keep overheating, which I thought was my 180* tstat but there was like tiny little gunk in it. I put my stock back in but it still overheats.
Well I went and got a new stock tstat and super flush, but is it necessary that I have to drain the rad or can I just drain from lower coolant hoses and then flush it out? I couldnt find the drain plug on the rad and I looked where its supposed to be.
And this may be dumb but should I just keep the tstat in there during the flush, then put the new one in and fill the coolant?

i see you got a 99?...do you know if the coolant has ever been flushed or anything?...because dexcool starts to become corrosive/acidic when its not changed out after a while and starts to eat the propeller on the waterpump...just an idea, that could be one of your problems....i would guess that you can have a pressure test hooked up to see if your waterpump output is ok...anyone else have any input?

I bled my cooling system cause I think there may have been an air bubble in it. It seemed ok when I drove it but Im gonna let it cool off then drive it to see if its ok.

That could be it, a bubble in the system

Yep, runnin around 200-205 now which is what I should be at with a stock tstat.
