flushed system today, added coolant & distilled water according to specs; runs hot and heater will not get warm; I think air in system and can't get it out; ran hot, relieved pressure via cap, filled with extra fluid, happened again...

sounds to me like the waterpump ain't pumpin' frequently the vanes on the pump are corroded away....from a PANIC refill with hose water...then NOT gettin' that stuff out of there right away~

Was it doing this before you flushed the system? If not then open radiator cap and crank it up and let it idle for a while. Watch level as it idles. As level drops in radiator add coolant/water. It might take a while but eventually you will get it all out.

Oh also have heater set on max heat while doing the above. This should get the air out.

you could get a thermal gun for 17 dollars...the cats go nuts over the ruby red lazer~ that way we'd see exactly where's it coolin' okay~

I think it is possible, except closed, not open, from reading his thread...

you know I'm of a mind that pumpies not pumpin' no more~ you could pull the t-stat out and would not help~

Was it doing this before you flushed the system? If so take the advise of judgeroy and davidh25.

How did you flush this ohe? put the heater on....connect the heater to a garden hose?.....at the shop we had a fitting on the hose so that you could BLAST compressed air along with the water to "scrub" the cooling jacket clean...plain water at gardenhose pressures may not be enough...if it was really bad we'd punch out the freezeplugs unscrew the water jacket drains and let it flow a good long time....combined with blasts of air usually did the trick~

What about the heater blend door? Could check it. Is it the 4.7 engine? If so, you have a bleeder screw located on the front top part of the engine. Does your temperature gauge show the normal temperature? If yes maybe your thermostat is O.K.

After this has happened to me twice with two different vehicles, I figured I'd help the next guy. It's most likely the radiator cap not allowing the coolant system pressure to be at normal operational temp to prevent boiling by maintaining pressure in the coolant system. If you have any doubts it's $6 to $15 part so just try it before digging in to far. Also I have read from mopar that they recommend changing the cap every few years.

Oxalic acid dissolve and tell no longer soluble in a gallon or two of hot water pour it into your radiator just your radiator and let sit for 1 hour and watch the calcium or lime deposits Fall Away worked like a charm after several radiator flushes and a trip to the dealer I even bought a new radiator just in case now I don't need one

I have a stumper 99 dodge ram v8 360 offroad edition with transmission cooler.....my dodge for some weird reason and this happens every 2 months or so will redline...I went threw 4 thermostats in a year and brand new radioator and everything...so this last time I decided to just releive pressure off cap while it's running btw upper radioator hose when it's overheating is harder than to horny rats in a wool sock...anyway it's running 213 releive pressure hose goes back to normal and it's running 230....I take the cap off and fill it up and truck instantly cools to 192.....I burn threw about a gallon every 3 months and I cannot find any leaks...There is however this antifreeze smell from time to time but truck will run perfect till this pressure buildup happens....I'm stumped and really it's just a hassle to every month or so bleed off pressure....then wait till next time..Sometimes doesn't happen for 4 months?

Hey guys, my 2013 ram 4.7L is running hot. replaced thermostat and water pump. Still running hot. I have also flushed it out. What else is there to replace? BTW, only half of my vents blow warm air (passengers side) driver side is cold.

I have a 2013 Ram 1500 5.7, replaced the Tstat and still no hot air into the vehicle. The mechanic unhooked the hose from the water pump and said it was just trickling out. He said it was the water pump. I held off to read more about it. If it were the water pump wouldn't the engine over heat? Next thing was to try a blend door actuator unless someone can convince me that it could still be the water pump. Temp on vehicle has never gone past 3/8 on the meter since I've owned it. Thank you all in advance

Have a 2013 ram 1500 with a 4.7 did a timing cover and now have barely any heat and the coolant in the radiator stays cold. When I went to fill it after the cover I didn’t take into effect that the thermostat was at the bottom of the motor. Block got hot and red lined. Shut down and filled through the upper hose. Any ideas?

After doing more diagnosing, checked both blend door actuators below radio, replaced thermostat. I then realized the air was warmer on the passenger side and semi cold on driver side. A friend of mine spoke with a certified dodge mechanic and he has known for sometime and he said he was almost positive it was the heater core. Apparently it has a left and right side in the vehicle that blows across it. I am having that replaced in a few weeks and will see what happens and repost.

I have a 1994 Ram 1500 3.9L. It was leaking near the thermostat housing. I replaced the water pump, thermostat (195 degree), thermostat housing, hoses, and both temperature sensors. I flushed the system with a garden hose connector. Now the temperature gauge shows too hot (around 230) and it seems the thermostat opens, but the system doesn't pressure up. Used a Lisle funnel to get the air out. What does the 2-wire temperature switch actually do?

I found a leak behind the timing cover and am in the process of replacing the timing chain and gasket. Not sure if this will solve the other problems.
