I have a 1996 fl70 with a 3126 engine and a 6 speed trans with 255/70r22.5 tires on it. It has a 14 ft rv camper box on it and I pull a 20 ft gooseneck flat bed trailer with a race vechile on it. The problem is that going down the road the engine fan is almost running continuos if you are running 65 mpg in 80-90 degree weather.
I have put in 2 new thermostats, 2 new radiators, new water pump, new fan sensor, new turbo (waste gate froze up on old one), checked shunt hoses, changed coolant mixtures, pulled muffler off and ran a straight pipe ( did not help), pulled wire mesh screen off of frt of a/c condensor, talked to local cat dealer. Freightliner says that fan should come on at about 205 degrees (pretty accurate with temp gun) and hot light comes on at 217 degrees with shut down starting at about 230 degrees. I have not had the light come on or shut down take place. just the fan running continuosly.
If anyone has info on this problem please e-mail me if you have a solution at [email protected]
