I do think that all the air had been purged.... I am still running hot and it didnt do anything for me to jack the nose up.... I didnt get anymore coolent in it at all.... In fact I lost some after the thermostat had opened it would run out the mouth of the radiator then drop then run out some more.... I dont think that there is any air in it but I dont understand what all the tiny bubbles are.... is this normal and should the coolant in the radiator be warming up before the thermostat opens?

Are you sure you don't have a blown head gasket?

No not sure of anything..... I have no oil in the coolant and no coolant in the oil but I have question about the exhuast leaking into the collant.... it is odd that the coolant doesnt make large bubbles of air.... it is smaller then carbination in a can of pepsi... I heard something about a tester for carbon in the radiator but when I went to the local parts store nobody had any idea what I was looking for...

Having no coolant in the oil and no oil in the coolant would not be unusual. Check for water coming out the exhaust. If it is, smell it to test for coolant.

You should go ahead and retorque the head gaskets. If they're leaking, you may be able to salvage things.

Yes, I was just about to post the same advise.

I have no water from exhaust and no smoke or any sign of head gasket failure other then the tiny bubbles from the radiator..... I have located a block tester and will be doing a test for exhaust in the coolant later this evening.... The one thing that is puzzling my brain today after messing with it is that when the heater is running it takes longer to heat up.... And the fact that I am getting warm coolant in the radiator before the thermostat opens.... I didnt think that anything would return to the radiator untill it opens the thermostat.... I could feal warm coolant in the radiator before the thermostat opened.... Is this normal??? What if the heater core lines were hooked up backwards would this have any offect on things?

Well, I guess that only leads to the next question. Is your waterpump flowing the right way. You've got me determined to get this resolved.

I have tryed two different water pumps.... I have tryed the old water pump that kept my 305 nice and cool and a new water pump.... Same heating issue with both pumps.... I can watch the thermostat open and the coolant flow across the top of the radiator from the top hose.... it seams to flow pretty well..... I have a pully for the serpintine belt but it is running in standerd rotation. (spinning clock wise)

I know that when I run my truck that has a 350 in it as well you can watch the temp gauge climb up untill the thermostat opens and then the temp guage will drop back down do to the cooler coolant coming from inside the radiator cooling things down.... The jeep that I am having the problems with does not do this... the guage just keeps slowly climbing even after the thermostat opens..... The coolant in the radiator is warming up before the thermostat opens so when it does open it isnt cooling the engine down.... I mean this is what I am guessing is happening.... it is realy odd because you do not see any movement in the radaitor through the fill cap until the thermostat opens but if you stick your finger in it you can feal the coolant getting warm..... Any thoughts? It is a MR. Gasket performance 180degree thermostat... do you think it is not closing all the way?

I was just going to suggest you may have a thermostate problem when my messenger popped up. I don't know for sure. Try swapping it. Then maybe check the valve adjustments.

The reversed rotation pump sounds the most plausible. Can you verify that water is being pumped into the top of the radiator from the water neck (not vice versa) and back into the engine from the bottom hose?

I have allready done the valve adjustments and that didnt seam to be an issue....

I asked some friends if they recognized these symptoms.

All I got for you is bad/wrong water pump and bad/reversed thermostat.

??? I am out of clues for ya.

Thermostates spring side should be facing down in the engine block. If that's ok then maybe the water pumps is after all reversed flow.

You mentioned earlier you have a serpentine belt. Did the other engine use a serpentine belt?
