Just a quick question. I just returned from taking my daughter back to Vanderbilt U. in Nashville. Got back to San Antonio and noticed a clatter from in front of the engine. Popped the hood and noticed the water pump pulley vibrating back and forth kinda 'radical' to say the least. Truck is now stopped until I change the water pump. Has anyone changed one on an '03 RAM TD?? How difficult is it?? Is there a good tech writeup on it on the forum?? Last but far from least.............Cost?? Thankls guys and gals.. Semper Fi! P.S. Yeah, I've changed water pumps before and know the signs. Just never changed one on one of these trucks.
