My son drove my 99 durango 5.9 with a bad waterpunp
hello I hope i can get some answers here I have a 1999 durango with a 5.9 my son drove it for about 2 weeks with a bad water pump. I changed the water pump but the engine still over heats and when i keep it on for about 5 minutes there seems to be pressure building inside the engine that the houses pop off i want to know what else could have been damaged inside the engine and is the engine ruined.

as long as it was not run after it got in the too hot range the engine is still fine, i would suggest doing a full cooling system flush you probably have gunk built up inside of something (most likely the radiator), and make sure none of the hoses are cracked/collapsed and you have the correct radiator cap (15psi i think) on it bc that should go before you lose hoses

i would be worried about a cracked head.. Not really sure what to check to see if that is the case.. guessing how you knew the water pump was bad I'm gonna figure that the water pump was already really bad.. worst case i could see the car being run without water for two weeks.. that could very well be a cracked head.. Keep a very good eye on your coolant/ oil levels.. If it ends up your loosing alot.. then you need to get major maintenance done..

thank you for all ur suggestions um yeah when i got the truck back the waterpump was making a very high pitch sound and leaking coolant allover theres no oil being loss only thing im loosing is coolant because the houses pop im going to check the radiator cap. REBELBOY there is no bubbles on the overflow how do I check the radiator for hot/cold spots my self I would rather not have it towed to the shop just for a check

Problems like these usually are caused but compression being introduced to the cooling system blowing the hoses off.

"This could also be an ecm issue. All of the 1999 durango ecm computers fail eventually. My ecm failed then the truck started to misfire. The dealer quoted over a thousand, I finally ordered a rebuilt ecu. ":icon_lau gh:
Sorry but really?
+1 possible blown head gasket or crack, napa sells a chemical test kit to check for hydrocarbons in the cooling system.
+1 possible cap, the cap is the pressure relief valve of the system, it could be stuck or just incapable of keeping up with the additional pressure of a head gasket leak.
It could also just be a stuck thermostat, but check the head-gaskets first.
Replace the cap & t-stat every time you service the cooling system, they are cheap, often overlooked & very important to the system functioning properly.
