When the car is on it makes a grinding sound.I found the pully on the water pump is lose.Like its bearings are bad.Was wondering if the pully comes on the pump and i need to change it or is there a way to fix the pully alone.The car does not leak nor does it get hot
The pulley on the water pump is separate from the pump on both the 6 and V-8 engines (you didn't specify which engine was in your truck).
If the pulley is wobbling around and grinding, the bearings have failed on the pump. The fact that it has not leaked is not unheard of. REPLACE THE PUMP! Continued operation will cause the impeller (the side of the pump which moves the water) to chew up the housing. Not to mention leaving you stranded.
