These fuel heater groups raise the temperature of the diesel fuel before it goes to the engine so it will flow freely in cold temperatures. Engine jacket water is used to heat the fuel in the heater. These groups are installed in similar procedures for all machines. See the instruction that follows for the correct installation procedures. Use pipe thread sealant on all pipe thread connections.3T1356 Heater Group (D8L)
