It should be on its own closed loop with the water pump, as far as I can tell. That was before the in-frame. Quote Link to comment Share on other sites More sharing options...

I did have that filter split on me...and maybe also a lower hose split...but that was before the in-frame, and the same thing was said, bad liner...so we may have been dealing with multiple issues, the bad liner causing the filter failure, and something else causing the radiator failure... maybe?

Always felt 460HP was a cruel request for that block. Macncheese recently lost his heads too. He had the hot rod AI467HP (at the wheels) engine. You know these guys are running sanely because it's their truck. Quote Link to comment Share on other sites More sharing options...

My buddy is getting a 5 bunk, tri-axle log trailer to stick behind the Granite tractor we have been tweeking. Stories like yours make me nervous. He is a born operator, but I'd gamble a lot of these guys are also. Quote Link to comment Share on other sites More sharing options...

Racecorr Posted January 8, 2018 Author Share Posted January 8, 2018 Ok fellas, I've heard from my mechanic and it appears to him that the screen is about 15%-20% blocked. Question, is that enough blockage to cause all of these radiator problems, or should he keep looking for the culprit??? Also, I've found out that the motor is a AC, and the water pump has been changed, does anyone know the difference between the two pulley sizes??

Racecorr Posted April 29, 2018 Author Share Posted April 29, 2018 Ok fellas, after a good flush that produced about a cup of some unidentifiable scale and a new oil cooler inlet screen, my truck has ran flawless. Thanks for all the help. Quote Link to comment Share on other sites More sharing options...
