One Last thing about my '71 Emission (CEC) System restoration
Took the '71 for a drive with the A/C on - intentionally looking for stop and go traffic. Pretty easy to find on a Saturday by the City Dock in Annapolis.
Saw a BEAUTIFUL burgundy Mid year 427 coupe with aftermarket side pipes! Told him he had a brake light out. Anyway...
The CEC solenoid did just what it was supposed to do when the engine temperature got just above 210* on the instrument cluster. It was HOT. Who knows what the actual temperature was, but the temperature sensor in the RH cylinder head activated as designed.
Normal cruise temp for this car is a good bit below 210* on the gauge.The solenoid kicked on and increased the RPMs to right around 1000 - increasing the air flow through the radiator, and reducing the temp back below 210* on the gauge.
It also increases as designed when in 3rd or 4th gear no matter the temperature.
I had previously had problems when HOT (not overheating) in stop and go traffic where the engine would bog-down and if I didn't keep lightly pumping the throttle, it would stop altogether. It would seem that problem is a thing of the past now. I got moving again at normal speed through town (35mph) and when I got to the next traffic light, the solenoid had deactivated and idle was back at 600RPM.
I was always of the mindset from the '70s that emissions control stuff was there to be taken off as soon as you bought the car.
I am now a convert.
Thanx to Alan and others here for your help and insight while I tackled this project.
