Re: Overheating/rising temp since A/C Charge

["jtrealtywebspannet" <jtrealty@xxxx>]

Bleed all the air out of the cooling system
Make sure both fans are running
Make sure they PULL air into the radiater front to back
Make sure the fans are tightly attached to the fan motor shafts
Replace the otterstadt switch and seal
Install a 40 amp circuit breaker for the cooling fans
Use a Fanzilla or similar device (not a wire bypass or fan fail relay)
Inspect the radiater fins for leaves or debris blocking the radiater
If you do all of these things it should correct the problem.

traffic though, or (of course) when at a stand still, the water temp 
rises steadily to the red zone. And then hovers there for a bit, and 
then seemed to drop drastically back to slightly under normal. 
Sometimes the water temp will stay at normal even in stop-and-go 
traffic, and other times it will do as i described above. And if the 
temp is high and I start going faster for some distance doesn't 
immediatly effect the water temp (as it has in the past when the temp 
rose is trafic.. it used to drop back to normal once the fans kicked 
on, or when i started moving again).

in from the radiator (pulling more air through? thanks for any
