It could be carbon buildup.Run some GM top engine cleaner through it and also check to see if the EGR valve is working properly.If it were a knock sensor problem it would turn on the check engine light.

I'd say check the Egr valve and solenoid to make sure they are working right also.

you should also find your quick disconnect to the vehicle computor (spout connector) as it is called, and check your base timing setting ,it should be 0.....ford5

This is a little off base but since wer`e talking trucks our`s is overheating under loads such as pulling the race car and just going up hills I have replaced clutch fan,flushed radiator,cleaned out fins, replaced thermostat twice finally took it out and it did help but it is still gets too hot under loads.It gets up to 240 also rechecked timing.this is on a 88 chevy 350 94 motor had about 70,000 on it when we put it in.thinking about changing the water pump.Other than this it does run good. any suggestions?

Another stupid question, do you have the proper rotation fan on it or even the water pump which would for sure cause it to get warm on a load.

Tim, make sure that fan isn't a flex fan and if it switch to a steel 4 or 6 blade. A high volume aluminum water pump would help, this may sound stupid but check the air in the trk & trl tires to make sure their properly inflated, and if none of that works you may have to switch over to a larger 4 core radiator.

Big radiator,if the water pump was wrong you would overheat quickly and it would go to the moon on temp not just 240.

Make sure the A/C condensor is in good shape and not restricting airflow.Also make sure your lower valance is on under the front bumper,if not the air will not flow through the radiator.Make sure you have 9-13 lbs of fuel pressure.

It will suck a rag to the air condtioner condensor real good at an idle and it does have the spoiler on the front. I dont understand why that would matter. I did not check fuel pressure. It only gets hot going up hills or pulling something.

Flushing the radiator may not be enough to clean it out, it may need to be cored at a radiator shop.

To clean the top of the motor try using just a little water thru the throttle body,it'll turn to steam in the cyl's and clean them,not as good as the top engine cleaner mentioned but alot cheaper,be ready to replace the plugs tho,and the catalytic converter may clog,that would be a good time to replace it with a pipe.

ctfarm, i forgot to add that the engine light is coming on, so maybe it is the knock sensor..not to brag about chevy trucks but this rig has over 260,000 miles on it!!! i change the oil every 3500 miles and it does not leak or smoke any oil but i do have to add a quart between changes i guess its just soaking it up somewhere!!
