Ram 1500

Coolant Loss and Engine Overheating on Dodge Ram 1500

Problem Description and Possible Solution

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.

Antifreeze is leaking from behind my water pump next to the block and I just replaced the water pump
Antifreeze gone without any signs of leaking. Smells heavily of antifreeze in the coolant bay. 2nd time this has happened withing the year.
Leaking antifreeze out back of motor can not find were it is coming from yet took starter off to get a better veiw of were it is coming from.
the truck is overheated and is leaking coolant out where the pulleys
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 truck overheats and I have a small radiator leak that comes out slow on the bottom left of the radiator. How to fix it so it want continue to overheat? I,ve have replace the water pump and the thermostat and it still run hot.
My truck is loosing coolant I cannot see any leakage .I have been refilling coolant. Don't know what is wrong.
leaking coolant arround timing cover, seal replaced
Water pump been replaced twice. Thermostat been replaced. Timing cover gasket replaced. Intake manifold gasket replaced. All failed one right after the other.
replaced the water pump. Now it's leaking coolant from somewhere up high behind the water pump.
How does a dodge 4.7 run with warped heads
Leaks water and gets hot water pump has been replaced...and still leaks
my anti freeze started coming out of all gaskets.
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.
replace intake gasket
my friend decided to do one hell of a burnout in my truck and blew my intake gasket
In a period of 11 years I have had to replace the water pump, thermostat and housing 5 times, and sometimes the fan clutch needed replacement.. This is very annoying and I'm hearing that this is a common problem with the Dodge Ram and it should not be that big of a problem. The cost of repairs range from $500 to $900 depending on the location. Dealerships have charged a lot more than off site certified mechanics. I feel like there should be a recall on the whole cooling system, given it's known problems by RAM truck owners.
Replaced thermostat, then leaky water pump, now it's leaking out of the timing cover gasket
Broke bolt in thermostat housing
