Ray / Ross it cooled off some -still a little warm - I took hold of the fan blades ( I remembered to turn it off first) and it move side to side a small amount-- by that I mean the tip of the blade moved maybe 1/4- 1/2 inch plus there was a slight click when I did that. Again I don't know if that means anything Dave S

I would do the compression test, it's pretty easy. If you've got a new WP on the way, it can't hurt to pull the old one. Is the fan on the WP shaft? It sounds like your WP may be close to dead, whether that's the problem or not.

Hi Ross yes the water pump is on the fan shaft. I'll get a compression gauge either out of storage or a new one and do the test. I haven't ordered the pump yet and was waiting until other possible solutions were tried. I assume the compression test will tell us (notice I said us as you and Ray are an important part of this repair) if the head gasket is ok or a stuck valve bad rings??

If the problem showed up suddenly, where the water pump is not moving water, my SWAG is it tossed the impeller. With the belt loose, you should feel very little to no play in the shaft. In the interest of getting the cooling system cleaned, I would remove the thermostat and use some cleaner in the system.
Plan on a new thermostat.

Hi Ray. I'll do the compression test, then loosen the belt and check fan. I'm going to order the pump so I at least have it available. I'll let you and Ross know what happens. Thanks again or yet Dave S

Hi guys. Did not do compression test as I can't find miy tester and the 2 auto stores near me don't have any in stock. Pulled water pump. When I took fan off the cup below the shaft was full of water. I didn't spill any. Took the pump apart impeller looks ok but very hard to spin.

Ray & Ross are pretty damn smart figuring out a problem even on line!
Did the compression test and 2 cylinders were zero. Gasket ? Valve? Time will tell when I tear it down soon.

Got the head off blown gasket between 3&4. Ross & Ray hit the nail on the head. Great guys to know and respect their knowledge. Two of the nicest guys you will ever meet and are not afraid to help you out.

It's fixed! The "R&R OLRS" (Ray & Ross ( or Ross & Ray) OnLine Repair Shop) deserves all the reps I can give them. The head gasket was the problem. Got a new one which the mail lady decided it should be stuffed in the mail box and destroyed it. Got another one sent FedEx so it arrived ok. Put it in today. Compression test shows one cylinder low but that's life.
Both Ross and Ray gave me step by step instructions to figure out what was wrong (both said head gasket right off) but still walked me thru it. Told me what was the best sealer/gasket maker to use. How to clean the head bolt holes with a chaser not a thread device and what anti seize bolt sealer to get. They were patient with my stupid questions and never hesitated to explain what and or why. I've had the pleasure of meeting both of these guys at Truckstock get togethers and have enjoyed their stories, knowledge and willingness to help others. If you get the opportunity to meet them don't hesitate you will really enjoy the time spent. Again thank you. I feel I just can't say that enough to the two of you Dave S
