Engine overheating

Are you sure t-stat is in the right way? What I suggest at this point is to rent or borrow a temp gauge that you place in the top of the radiator to see if the temp is getting as high as you think it is. I really feel the sending unit is the problem. With the engine cold, open the radiator cap, place the thermometer in the coolant and allow the engine to warm up. Then you will know exactly the temp of the coolant and if the gauge is correct.

Let me know what you find.

What could be cracked or broken? Coolant shroud?
The shroud is fine. I'm not getting any leaking at all anywhere. I'm guessing the fan clutch isn't pulling enough air into the radiator to keep the truck cool.

Well after a day long of messin with my truck, I figured it out, you might wanna grab a seat cause you ain't gonna believe what it was. My truck is designed to run on a certain kind of antifreeze, I have always put in it the pink kind, or 50/50, after the timing chain cover gasket was changed the garage that actually changed it put back in it the full strength prestone antifreeze, and dumb me never even thought twice about it until today, flushed it out completely and added the 50/50 it is under normal operating temp, the sending unit is good as was it before and my truck is running like a brand new one. I just wanna say thanks for your input and all ur advice, so from here on out I will do all my work as I have done before and never intend to take it back to a garage again, I messed up a good thing just because I was to lazy to do a 3.5 hour job. Thanks a million, really appreciated your time and advice. Misse

The shroud. The black thing around the fan that acts as a suction from the fan to suck the air through the radiator to cool it.

Trying to find out what would cause my Ram to overheat within a mile of driving.
I tried last night to disipate some of the heat buildup by turning on the heat and noticed there was still cool/cold air coming from the vents. After about 15 min hot air started coming out. I checked the oil when it cooled down and saw it was a quart low. Would being a quart low cause my engine to overheat that fast at low speeds or does this seem to be a thermostat issue?

Hi
Thermostat replacement is good idea also consider flush at that time. Check to see if fan clutch is locking up when at op. Temp. Ie. Should be hard to turn by hand.
Let me know
Thanks for donate

Turned out to be a hairline crack in the radiator frame. Replaced the radiator as well as the thermostat and all is good. Autozone had a direct replacement that made the swap really easy. Thanks for the response and informative website.

Sounds like the head gasket(s) failed. Coolant is getting into the combustion chambers, not good at all. The engine may need some major repairs.

We have a dodge ram van 1500 that we bought to pull a trailer (1100 empty + 800 lb motorcycle) and the van runs just at or under the red section of hot on the gauge. Replaced thermostat, no didderence. Would a transmission cooler that u-haul sells improve this?

The trans fluid is fine and when they suggested the trans cooler I wondered if it would really have any effect on the cooling system. Don't want to waste money. Thanks!

It won't, I'll probably cool the transmission faster to prevent the engine from overheating- due to the weight you're pulling/long hauls

How many times you have to ask the same question-if the transmission cooler can carry the load -best have the transmission checked out could be slipping causing the engine to overheat

Have you had the radiator cleaned, you may have a partial blockage in the core tubes restricting circulation, often not evident until a load like towing is applied.
