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.

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~

...could very well be a stuck closed thermostat as H25 said~ under 20 dollar fix~

With the heater blowing cold I'd say low on coolant because system is air bound, faulty water pump, clogged heater core indicating that the cooling system passages elsewhere in the system are blocked with deposits. Perform a chemical flush. I've used Prestone Super Flush with good results. BUT be prepared for something to spring a leak. This is a powerful cleaner so if something in the cooling system is questionable (radiator, water pump, etc.) it'll start leaking. If it were a stuck closed thermostat you'd get LOTS of heat from the heater. Unless, of course the heater wasn't working before the overheating started. HTH. -Jim

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.

You don't have enough water,, run engine till stat opens and then let cool down. open rad cap and add more coolant

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?

Conner, how long does the system hold that kind of pressure? When the engine cools down there should be no pressure at all. HTH. -Jim

Derrick, you may have air in the cooling system. No heat is a good indicator of that. You may also have a blown head gasket. With the engine cold, pressurize the cooling system with a cooling system pressure tester to 16 PSI. The pressure should hold for a minimum of 15 minutes. If not, it's leaking somewhere. To check for a blown head gasket, pressurize the cooling system, engine cold, and start the engine. If the needle on the pressure tester's gauge bounces the head gasket is blown. HTH. -Jim

2003 ram temp gauge eases towards hot only when I drive over 70mph. As long as I'm at about 65 or below it's fine
