:blush: I'm new to this site and excited about finding it. We are the proud owners of two Airstreams. Our trailer is a 1966 20 ft. Globetrotter that my husband and I have completely redone inside. We haven't gotten the mirror finish on the outside yet-another project. Our second Airstream is a 1984 31 foot Class A. We call her our Classy Lady! She's pretty much vintage inside. We drove from West Virginia to Dallas,Texas to pick her up last year on the day Katrina hit. We do have some questions about her mechanics and hope that some of you can help. She is on a GM-P-30 chassis with a 7.4 L. engine. She has a Banks system . We do a lot of mountain driving and wonder at what temperature should we be concerned about the motor over- heating. We are consistently running between 212 and 220 degrees.

Welcome to the Forum - I'm new here also - great place for answers. We are originally from WV so yes you are doing some mountian driving. Here is some info. from "Experts" site - looks like you may have a temp. problem..?

Subject: 7.4L Low power and Overheating

Question
I have a 1996 Chevrolet 3500 HD the entire cooling system has been replaced with new parts and I still seam to have a problem with the temperature running about 220. It dosen't seem to have the power that it should have for such a large displacement. The truck has a little over 50,000 miles on it and has been expertly maintained its whole life. This has the mechanic who has always serviced it and myself puzzled. I will be grateful for any suggestions.


Answer
The operating temperature is too high and will, if it has not already, damage the engine.

A vacuum gauge is still one of the best diagnostic tools out there. It can tell a mechanic about the condition of the valves, valve timing, and exhaust system as well as detect intake leaks.

In fact, one of the things I would check for is a restriction in the exhaust, either in the catalytic converter and/or muffler.
