How important is a torque wrench,if so what is the proper fp torque for pump/pulley ?
It shouldn't be that critical for water pump bolts. It is extremely important for something like engine head bolts because of the extreme pressures inside the cylinders. Just refrain from over-tightening. I've replaced a number of water pumps and have never used a torque wrench.
dont need to tighten until good and snug torque is critical on head bolts and bearing cap and rod cap bolts etc
