it costed me 1900.00 to get the water pump done as well as the timing chain and oil change and the belts replaced and plugs changed .....i was just going into get the truck checked out then we seen the over flow empty and antifreeze driping on the ground so .....so had no choice but to fix it.......12 1/2 hours of labor for the water pump so replaced the timing chain since they were in there anyways
