A while back had the water pump replaced and daughter drives the truck. I drove last weekend and there was a distinctive sound like a vent door closing or something along that line bumping sound when driving with the heat on. She tells me "Oh Dad that started right after the water pump was replaced" yep that was six months ago so been going on for a while. I checked and when running I could hear a pounding sound coming from the firewall and when the hood was open near the radiator. I will presume it has something to do with the water pump that was installed. I did open up the system to ensure there were no air areas left that had not been bled out. Any help appreciated! Truck currently has 298k on the ticker and running like a top besides this bumping sound.
