Engine overheating?

Yesterday morning, the truck started fine. I put it in reverse and it died. Started back up and it was fine. On my way home from work last night, I tried to slow down at a stop light and the engine really revved up. I looked at the temp and it was coming close to overheating. I pulled over and shut it off in time. The RPM's had been going high prior to shifting so I'm not sure if it's related. I checked the transmission fluid. Fine. The oil was low. Added two quarts. However, I found green liquid between the fan blade and engine. What do you think? Cracked radiator? Antifreeze leak/low? Or water pump? I opened the metal cap on the radiator after it had cooled down but I'm not sure how much fluid should be in there. Help! Oh, one more thing. No check engine light came on.

My truck has over 114,000 miles on it and it is over heating. I dont see any sign of leaks coming from the upper and lower hoses. I havent yet check the thermostat but it was replaced last year and it seems like I'm always having to fill up the coolant. I'm a mechanic just starting out and even went to a trade school in 2004 but I just dont have the experience to figure it out please help.

Coolant has been spilling out of engine (not sure from where) when parked after normal driving. Will not happen if I leave heater on, but will still run hot.

I replaced the thermostat and flushed out system and it seemed to help some but after 15 to 20 min. Of highway driving it will begin to overheat again. Hasn't leaked coolant again, but it looked like it was coming from the bottom hose into the radiator.

Yes, it's still overheating. I changed the thermostat and had it flushed out. It hasn't leaked coolant again but I've had to keep the heat on to prevent it from going above 210. I checked and it seems the leak from before was coming from the lower connection to the radiator. It takes 15-20 min for it to begin to overheat and I can keep it down if I run the heater on full blast. The radiator fan is running. I'm not sure how to check for the radiator itself to be plugged or corroded.

Thanks for your help,

HI:

haven't responded back to this problem due to freezing temperatures outside have made it impossible to work on truck.
The cold temporarily solved the problem but with warmer weather this past weekend the problem is back. Checked the hoses and they aren't collapsing. I'm guessing this means radiator is the problem? Also The check engine light came on while pulling into the drive way, gave a P0132 code (scanner said it was the governor pressure sensor voltage was to high). The truck seems to have very little power until 30-35mph although not much better after that. Has a severe leak of tranny fluid which I can't tell if it's a hose or the main seal. Could this leak be causing the problem? I read online that that code was an o2 issue. Not sure where to start.

Thanks for your help

I was driving around 10 miles from home, when the truck suddenly overheated. I let it cool and was near a pond, so I used a plastic container to pour water on the radiator. After the radiator cooled and was full of water, I tried to restart the truck. It cranks over, but will not start.

I am experiencing overheating when truck is under load such as going up a hill. Its not boiling over but gets real hot. I have flushed the cooling system. The water pump shows no signs of fault. I am not loosing any coolant. THe hoses look good. The fan clutch appears to be OK. I changed the thermostat. It doesn't appear to be related to a head gasket. The truck has never overheated before. I checked the timing and it reads 15-17 degrees. What in the world do I do next?

Hello, I have a problem, my 1998 dodge dakota is over heating. In August 2009 I had my transmission completely rebuilt (was shifting funny), when I got my truck back, the belt was sqeaking, and truck was getting hot, I replaced the belt, still squeaked and overheated, then I replaced the water pump, same problems, then I replaced the clutch on the fan, no more squeaks, but still overheats, so onto the thermostat, I replaced it, still over heats. I completely flush the coolant system every year, like wise I completely flushed again. Still I am overheating. Minus replacing the $400.00 radiator, I have done everything. My radiator shows a temperature of 260 at the top, 150 in the middle, and 250 at the bottom. The clutch only sees the middle so it the disengages. All problems came about after trans was rebuilt. Could the trans be loading me engine making it work harder. I am unemployed, have been for 3years now, I have little money, and limited transportation. I can't afford a donation. If I get this fixed I can get a job, then donate to your service. I live in the middle of nowhere, so transportation is a must. Please help.

First thank you for the response. I have performed a CO2 test and found no leak head gasket leak, I'm not loosing any coolant, and all hoses are in great shape. With the radiator cap off and at idle I have no problem, but going down the road about 10 miles, I over heat. I have alot of mechanics ( with over 15 years expirence) i'm friends with and they are all scratching their head.
