Subject: cooling system air bubbles
Okay, since we're on the topic of cooling systems I'll bring this up..
Basically, I'm suspect that I still have air in my cooling system. The =
car
runs at normal temp (a hair above the LED) until I get to a stop =
light.
After 45 seconds or so of sitting, the temp has risen to 3/4 on the =
gauge.
That never happened before, so I'm guessing there's still an air =
pocket.
I already burped several huge bubbles out including one that was over =
a
liter (it took that much water to fill the reservoir back up)
I haven't had a chance to idle the car and watch it warm up to see =
if/when
the fan is coming on (although it is on when I'm sitting at a =
stoplight
like that, since I had the blower on defrost and that spins up my rad =
fan)
because its so freaking rainy, but the radiator fan switch is only 2 =
years
old anyway and I don't think that's it.
When I have driven for a long time and park and pop the hood, the =
upper
radiator hose is all bloated like its full of air but if I open the
coolant reservoir partway its pressurized and just dumps coolant
everywhere.
Any foolproof methods you guys use to blow -all- the air out of the
cooling system?
I drilled a 3/32" hole in my thermostat in that part that looked like =
it
opened (the large disc shaped piece, not the spring-loaded small one =
at
the other end).. I revved the engine a bunch with the reservoir cap =
off, I
did a few heating/cooling cycles. I drove the car probably 60 miles
since I draining and filled the coolant.. What else is there?
I hate vw cooling systems..
