Finally put the truck back together sans Paxton (Sold it! Thanks Emilio!), and fired it up. Unfortunately, cooling problems cropped up on warm up, moving slowly up and over 200 degrees. Burped it, have fluid flowing in the rad, but noticed that the fan is turning pretty slow. The hydraulic fluid reservoir level is right on, and there are no power steering problems. Drove it a short bit and temps hovered around 195.

Had no problems before garaging it to remove the Paxton, and have changed nothing in the way of the cooling system. Aside from draining and refilling, I'm about out of ideas. Again, the only thing that seems odd is that the fan is turning pretty slow considering the engine temp.

Suggestions folks?:dontknow:

Sounds like maybe your fan is done.
 
also check your coolant mixture I did the same thing when I did my s/c it ran 180 and cooler took the radiator to pin the crank, it would not go under 180 stuck around 200 couldnt figure out why, then it dawned on me I made 60/40 and it should be 50/50 what a big differance that makes:dontknow: now it is back to normal after adjusting.just a thought.
 
Burp it again, I had do do it several times over the course of a week after changing to the JMB pipes.
 
also use the bleeder screw on top of the thermostat housing or it will take forever to get the air out. I know its messy but it takes 2mins compared to an 1/2 to an hour the old fashion way.

I have one of these and it works really good, pulls a vacuum in the cooling system and then uses the same vacuum to suck the coolant back into the engine. No air pockets ever if done properly. I use it mostly on tractors where the heater core is in the roof, much higher than the fill location and I havent had heater problems since.
 
Most of the time if the block is "dry" I pull out the bleeder screw and pour coolant in there, It helps get the air out alittle quicker. If all else fails you might want to try some "water wetter" or some purple ice from royal perp. It supposed to make the water seem colder to the motor, I dont know how it does but I have seen it work.

Yeah, guess I could have clarified that it was what I was doing to "burp" the system. Opened it several times while running and only got a little air out of it once.

Might just drain the system down a ways and try refilling part way through the bleeder valve port.

i sepnt over 150 bucks using engine ice in my truck and it didnt help one bit. it works great in my bike though.

(Insert Tim Allen primate noise here):dontknow:

I'm assuming that the solenoid is located where the fan harness plugs in, but exactly what are you thinking? Some contaminant has fouled the mechanism? If that turns out to be the case, I'll be pissed. I recycled the hydraulic fluid, but filtered it before returning it to the reservoir.

Quite frankly it probably wont matter anyway. The Procharger system is in the works, and it will mean deleting the fan assembly entirely to make room for the cog belt drive. Plus, I'll be draining off the cooling system again. It will probably be enough just to have it running to move it around under its own power when necessary. Snow's on the ground, and it's expected to be a cold one this year anyway.;)

Besides, this will be a good time to get wrenching on the Stude.:rock:
 
I have the test procedures for the fan solenoid as well. PM me you personal email so I can send you an attachment.....
