  1. To reassemble, reverse disassembly procedure. Use new gasket between pump and housing. When installing pump assembly, use new "O" ring between pump housing and engine block. Open heater control valve fully. Add coolant to expansion tank until coolant comes out of thermo time switch opening on coolant flange.
  2. Reinstall thermo time switch and connect wiring. Fill expansion tank 3/4" above full mark. Start and run engine until radiator cooling fans cycles on and off. Check coolant level. Fill expansion tank if necessary. Make sure coolant circulates (thermostat opens).
NOTE: For information on cooling system capacities and other cooling system components, see appropriate article in ENGINE COOLING SYSTEMS section.
