Hi, I have a 1998 Dodge 2500 Ram Truck with a V-10 , I cant get it to warm up, Blocked the radiator off in the front, Restricted the water pump hose from 1 1/4" to 1/2", Last thing I did was put a 1 1/2" valve on the upper radiator hose , and dialed in to where its 95 % close , so the truck wont over heat. and all I register is a 165- 170 degrees after running for a half hour. Shot the lower radiator hose and radiator and it is only reading 65 -75 degrees. It helped with a little heat but not much . ( at least I dont have to scrape the inside of the windows with a credit card while I am driving !) Any Ideas would help ??
