Re: IML: slight over flow from Radiator 66 Imperial



Are you filling the radiator each time after this happens? 

The old cars are not an overflow system like new cars so they need a small amount of space in the radiator for expansion.   If you fill it up it will "burp" out a little to make that room. 

Assuming that you are not refilling, the first thing I would look at is the radiator cap.  I am sure someone will correct me if I am wrong but I believe the correct cap is a 14 to 16 lb cap.  As caps age they tend to lose holding ability and yours may just be up for replacement. 

The next place I would look is a faulty thermostat.  If it is not openning at the correct temp it allows the engine to run warmer.  When you shut down there are more BTUs of heat stored in the block, etc.   This raises the coolant temperature and corresponding pressure which can lead to a small amount of overflow.  You would probably notice your car running a little hotter though.  You can check a thermostat by removing it and use a candy thermometer and a pot of water on the stove.  Heat it up and watch when it opens.  It should be close to the temperature stamped on it.

Best of luck,

Ron

Subject: RE: IML: 81-83 fuel gauge funnies

A common problem? I'm surprised. I've been driving one (okay one '83 or the other '82) daily since January 2000 and it's never happened to me before. I've also put over 300,000 miles on 3 different fwd mopars with digital readouts without incident. Those had the bar where a light goes out as the gallons are used. Not sure if you remember, but my car has had fuel delivery issues, and I believe it currently has a tank vent problem so I can't always fill the tank up. No need to worry about cooling the pump because it has been moved outside the tank by some hack. Guess I'll go through it next time I have off, but that won't be for another two weeks. 
 
On a seperate fuel sender note, my '83 is backyard converted toa 360/4bbl. I believe it still has the original dash. The fuel gauge reads full for about half and tank and then drops about twice as fast as it should. I am correct in assuming that has something to do with the voltage conversion on the efi dash as opposed to the conversion dash? Not a big issue for me, but I'd like to know. 
 
Oh, and Paul to answer your question on the list: YES, I STILL LOVE MY CARS!! This is fun! ;)

Also, sorry about the lack of subject in my first post. Had trouble sending it, so I cut and pasted and of course forgot to post the subject.
