BELT 5195250 - Caterpillar

INSTALLATION: The improved elements can be installed in earlier heaters. A 1 3/4"-3/4" drive socket is needed, and an impact wrench can be used if necessary to remove the old element. Use 5P3413 Sealant on the threads of the new element, and tighten to 110 N m (80 lb ft) torque. Do not use an impact wrench to tighten the new element. Leakage of coolant around the element threads can cause corrosion and/or electrical problems. Use 10 Gauge wire with terminal connectors, and be sure all electrical connections are clean and tight. Good electrical connections are important to keep resistance at a minimum and to prevent overheating (high temperature) damage to the connections. Connect the power source wires to one terminal of the thermostat and one terminal of the element. Connect a separate 10 Gauge wire between the other two terminals (one on the thermostat and one on the element).
After installation is complete and the heater is filled with coolant, check for coolant leakage before the electrical power is turned on. Never turn on electrical power to the heater when it is not connected into the cooling system and filled with coolant.
