Retrofitting a fuel computer on a 2002 Dodge cummins

From : clinton jensen

Q: the engine started to over heat when i took the fifth wheel over the cont. divide in july. it was not a warm day only 74 degrees f but it did turn the warning light on. i turned on the cab heater and it brough the engine temp below the alarm setting. i started using this procedures for the rest of the trip to alask and back and did not get an egine temp warning again. could be a failing fan clutch a failing/stuck thermostat an eroded impeller on the water pump a partially plugged cooling system etc. to test the fan clutch drive the engine until up to normal operating temp. shut it down and then try turning the fan by hand. it should be very tight. if you can still spin it by hand the fan clutch isnt engaging and should be replaced. drain a couple of quarts from the cooling system then remove the thermostat housing and check the thermostat. replace it if you even suspect a problem do the old drop it in a pot of boiling water test to see if its still good. on the cummins you can pull the water pump very easily - it just unbolts from the front of the block. check the condition of the impeller. take this opportunity to drain/flush/re-fill your cooling system since you should drain it before removing the pump or youll make a big mess. many heavy haulers opt to replace the viscous fan clutch with a horton electric clutch which is either on or off as opposed to allowing some slippage like the factory viscous clutch does. if everything else checks out and youre still experiencing a problem you may want to look into this option. .
