Code 528

[Ferendon]

Voltage to pin 10... A/C is off... What's the best cure. Running rich and overheating, replaced ECT sensor (single wire unit), and pulled superchip. I think I've gotten all the air out of the cooling system, but when I was adding coolant to the resevoir, I hearad a LOUD sucking noise, like the t-stat POPPED open. I mean, it was a real Pam and Tommy kinda noise... Car was running at the time, and was warmed up to slightly above normal operating temp. "RM" area... normal for me is "MA"

Tip #1: If you have a code, search for it and my user name. I've covered many of them, including this one.

Tip #2: Keep continuing problems or follow-on issues in the original thread instead of starting a new one. It makes it easier to follow sequences of events.
