My truck turned off by itself and a bunch of steam and smoke came out and my radiator was dry. To keep it running i had to have the engine revved and at a stop sign hold the brake down. and slightly press. I'm assuming its the water pump however. It started yesterday as the colder weather started. What my question is what do you think it is and if you have experience with water pumps, how hard is it to replace i found one for $14
that don,t sound like the water pump. if it was the pump then it would overheat and leak out. check to see where it,s leaking at. if it,s leaking from the pump then it will have to be changed even though it still might not help it to idle. it,s not really that hard to change the pump on a 351W . the hardest part is getting into it. you might have to remover some stuff so you can work. the belt and water pump pulley will have to come off and the fan but that should let you into the bolts.
