DRAINING & REFILLING COOLING SYSTEM

CAUTIONDo not remove surge tank cap while engine and radiator are hot. Scalding fluid and steam may be blown out under pressure.
  1. Place a pan below vehicle to catch draining coolant. Remove surge tank cap. Unplug drain cock. CAUTION: Dispose of used coolant to a used coolant holding tank to be picked up with used oil for disposal. Never pour used coolant down drain. Ethylene glycol antifreeze is an extremely toxic chemical. Disposing of it into sewer system or ground water can contaminate local environment.
  2. Catch escaping fluid in a drain pan. Remove all sludge and dirt from inside surge tank. Plug drain cock. Add clean water to surge tank. Fill tank slowly so that upper reservoir hose remains above water line. This allows air inside cooling system to escape.
  3. Start engine. Run engine until thermostat opens. When both radiator hoses are hot to touch, thermostat is open. Repeat Steps until drained water is clear and free of coolant and rust. NOTE: Never use an antifreeze mixture more concentrated than 60 percent antifreeze to 40 percent water. The solution freezing point increases above this concentration.
  4. Fill cooling system through surge tank with a mixture of ethylene glycol antifreeze and water. The mixture must be at least 50 to 60 percent antifreeze to water.
  5. Fill surge tank to specified MAX mark on outside of tank.
