I pulled the thermostat and its installed correctly, I checked the thermostat in boiling water and it completly opened by 180 degrees. I checked the temp gauge and that looks to be good.

I'm guessing i should pull the water pump to check and see if the impeller is moving? how would I do that, its brand new...The old one had 2 springs in the front of the pump and the new one had holes but no springs, should I have taken the old ones off and put it on the new one? Here is a stock pic of the one i bought...

If your water pump looks like the one in the picture, you have found your problem. the water pump is NOT turning. Two of the 4 bolts in the front of the pulley need to be replaced by studs which go through the two vacant holes in the front cross piece (the driver). two springs go between the hex on the studs and the back side of the driver. The driver must be removed to put the springs on.

So................you mean that you left out the springs and long pins????????

If so the pump is not turning!!!!!!!!!!!!!!!!!!!!
 
Totally agree. I just got back from the minibarn. I have an H pump assembly. Anthony all it is doing is turning the fan blade. You need those pins and springs so the blade can turn that front impellar on the pump shaft.
 
I seem to have a knack for learning things the hard way, not to mention that I already sent the old water pump to the scrap yard and cant remember if I kept the bolts/springs in my bag of old extra parts...Thanks for the help gentlemen, I appreciate it. ~Anthony
 
If you don't have the right ones you can use bolts and cut the head off and use a nut to tighten it down and go to your hardware store and get a two spring to hold the impeller in place. HTH

there's your problem! the water pump is not turning. you need to have those 2 studs with the springs to drive it.silly asses that sold that dont have a clue either.
 
Driver pins are very important to the turning of the pump. You are paddling, but the oars are not in the lock! Jim
 
Zach im not sure if they are the same but let me see if i still have them in the barn, if I dont ill take you up on that, thanks
 
Well, at least you found your problem, impeller not being driven. As far as the springs, the idea of the springs is to push the impeller forward making contact internally on the shoulder of the water pump impeller to the bushing. This establishes correct clearance for impeller fins to housing. Let me predict your next problem, not nearly as serious though. It will not come up to operating temp due to the corrosion in that housing allowing coolant to flow around the tube. It doesn't look too bad but they never fit really close even when new. In the diesel engines there is room to machine a groove for a seal which was used on later model diesel tractor so it prevents coolant from getting past that tube and directly into radiator. Like I said before, you can easily tell if coolant is leaking past by observing flow in tank when engine is cold and running. This is the most common reason for these old farmalls not warming up with out a load on them.
