Coolant Loss and Engine Overheating on Dodge Ram 1500

Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.

My 3.7 liter engine in my Ram 1500 is running hot. I replaced the coolant, flushed the radiator and replaced the thermostat. It still runs hot whether it is stop and go or highway driving. The water pump is pushing water and I verified the heater core was not clogged during my system flush. I am hesistant to replace the radiator or the water pump.

Coolant "disappears". No evident show of leakage except after about 300 mi., have to add coolant. This also happens with engine oil. Told head bolts stretch on this model with no recourse but have all replaced and head(s) repaired.

my friend decided to do one hell of a burnout in my truck and blew my intake gasket

The intake manifold is corroded so badly where the thermostat sits that I cannot get it to seal up properly. Looks like I will need to replace the intake manifold to stop leak. Seems excessive to have to replace the entire intake manifold to stop a leak. I think dodge needs to rethink & redesign and offer a recall to get this issue fixed.

Check gages light came on temp have showed hot. I pulled over opened hood pulled off cold radiator cap had fluid in radiator, and in reservoir started it back up lights were all normal. Went 3 miles it stopped dealer says engine is blown. Won't stand behind their warranty or the water pump that they installed in March of this year.

I am having problems with overheating also. I thought the water pump was bad so me and another friend changed and put a new water pump on. We figured the thermostat was still working, so I am still driving, now it only starts to overheat on long distance trips. I did discover a pin hole under the radiator cap. Still trying to figure out what the issue is....
