I have recently bought a 2001 Dodge Dakota quard cab 4x4 with the 5.9L 360CID it has 175k miles after about a week of owning this new JEWEL it developed a coolant leak at the water pump weep hole. r&r'ed water pump and t-stat now this thing builds up way to much pressure the coolant system is a 21 pound system and when i start the engine my pressure tester reads it to build to aroun 36lbs with in about 10 mins it was showing to run warm before the water pump and t-stat but now it gets realy realy hot. and builds enough pressure to blow most of the coolant out of the system. then i thought head gasket has an exhaust gas test ran on it no coolant in exhaust and no exhaust in the coolant but i am showing bubbles at the radiator filler neck? if anyone has any ideas I would be very greatful and might even by you a beer if Im able to get this thing roadworthy again.

The best way to do it is to either take it or do a compression test yourself... thats the hands down proof positive way to know

Try "burping" your system. On a Ford you do it by loosening the temp sender on top of the intake. Air trapped in the top of the water jackets will cause this problem. If that doesn't work you may need to change the thermostat. The best way to check for a bad head gasket is a compression test. The offending cyl(s) will show themselves. Good luck.

I doubt you have a blown head gasket, from the sound of it. More likely trapped air and cavitation.
Check the oil for water, since you see none in the coolant. Check the plugs for wetness, then bleed the air from the system...not necessarily in that order.
Good luck!

It appears that you did not bleed the water pump of air and is cavitation instead of circulating coolant, in this condition the pump will not last long also.
There should be a method to bleed the air out of the pump on top of it or near it on the top of the engine.
Good Luck

did "you" replace the thermostat? if you did pull it back out and make sure that it is installed correctly. your local repair center should have a product called block check. this product checks for exhaust gasses in the cooling system. you can pull all of the spark plugs and look for fowling but this takes an experienced eye. the only other way to determine if a cylinder head or gasket are bad is to remove them and have them checked.
