ok i have a mud truck iam building with the 2.8 in it. the bronco set for probably a year with \out running. i started it up last night and had all kinds of rust in the radiator. i pulled the radiator hoses off and stuck a water hose down the top hose a rinsed the motor out till the water was clear then put the bottom hose back on and pulled the cap and ran water through the motor and radiator again till it was clear then pulled the radiator drain and ran more water through. my question is can i use like dish liquid in the radiator then start the trruck up and let the soap scrub the inside then drain it and wash it out again? will this do the job and not hurt the motor? thanks rough

Just rinse it and refill it with 50/50. No need to do more.

Cleaners do not work in the cooling system. Pure water will get rid of the loose stuff. If the radiator tubes have clogging, you have to take the radiator apart and have it "rodded." Radiator shops run a metal rod down each tube cleaning out the crud.:)shady

Factory gauges are not always very accurate and sometimes the sender is faulty; but yes, the radiator may be plugged with rust. You just have to check everything.

Did you install a new 195* thermostat in there? If not that cheap item may be the problem. ALL engines need the proper thermostat in good working condition. Also at 280 degrees the thing should be puking it's guts out.. Your reading may not be telling you the truth.

did you try boiling the rad out with a caustic radiator flush? This will help to get rid of some of the rust that plain water doesn't get rid of
