my truck has been over heating and thought it was the thermostat well that seems not to be the problem, i cant make it across town before it starts trying to heat up on me again..i poped the hood when i got home and the a/c compressor was condesiated however u spell that and i wasnt even running the a/c once again its a 2003 does anyone know what it might be

 

Wellflow, first welcome and consider joining the 03 Forgotten Club. The link is in my signature. You mentioned thermostat. Did you replace it or test it it? When you run the heater, does it blow hot? Are you running a stock clutch fan? What do you think is the problem? Is your radiator coolant contaminated? Have you checked your engine oil? Does it look clean and does not look contaminated? From a cold start, can you watch the temp go up and see a dip when the themorstate opens? I am just throwing out ideas I look for to determine if everything is normal or not. Basically comes down to coolant flow. Stat, radiator and pump. Good luck...

 

im sorta thinking its the water pump but how do you know if its actually out or bad and where is the water pump located and is it easy to replace

 

Water pump problems are usually limited to a bad seal, leading to a bad bearing which causes the lost of coolant which leads to overheating.
Are you losing coolant? Bad water pumps are usually not really a pumping problem. Think about the questions I asked previously. If it is slow to overheat I am starting to think maybe some folks are having a clutch fan problems in traffic. This can be checked by running at highway speeds and having the temperature return to normal. Radiator caps can also be a source of losing coolant. Hang in there..

 

Did you say your AC pump was iced up and you were not using it?

 

yea the a/c was real cold and dripping water all over, seems like to much i like to think i can do stuff by myself sometimes im just gonna take it to the dealership i got a great warranty

 

Sorry -- you're thinking it's the water pump, but have to ask where the water pump is? Hmmmm. It's on the front of the engine, right behind the fan.

FWIW, yep, the pump is fairly easy to replace. Be careful with the coolant - critters like it and it's poison.

Anyway, if you grip the fan blades, can you wiggle the fan side to side or up and down?

Your iced-up A/C compressor is a different problem. That's often a result of not enough refrigerant or insufficient air flow over the inside coils, but work them one at a time. The over-heating is more important.

 

2003 and you have warrranty? Well done...

 

yea i got to make sure i got warranty and full coverage insurance lol ive had nothin but trouble out of this truck tho ever since the cam got put in it havent been able to do anything else to it

 

Does it run hot in stop and go traffic? Run hot on highway? Mine ran hot in town but was fine on highway. Fan clutch was bad check to see how easy yours turn by hand. If it turns easy by hand do the newspaper trick roll it up tight and start the truck and stick the ens on the fan clutch housing be careful of the blades. Mine stopped when I added pressure.
