The cooling system can be drained by opening the draincock at the bottom of the radiator or by disconnecting the lower radiator hose. Be careful not to damage the fins or core tubes when removing and installing the radiator. Always open the air relief plug before filling the cooling system, in order to bleed any trapped air. Only when the cooling system is bled properly can the correct amount of coolant be added to the system. NEVER OPEN THE RADIATOR CAP WHEN THE ENGINE IS HOT!

  1. Drain the engine coolant into a clean container. Remove the air cleaner inlet pipe.

When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  1. Disconnect the upper and lower radiator hoses, as well as the coolant reserve tank hose.
  3. Disconnect the automatic transmission oil cooler lines, if so equipped. Plug the lines to keep dirt from entering them.

  7. Connect the upper and lower hoses (use new hose clamps if necessary) and the coolant reserve tank hose.
  9. Refill and bleed the cooling system, as described in General Information & Maintenance . Operate the engine until warm, then check the coolant level. Check also for any coolant leaks.
  11. On automatic transmission vehicles, check the fluid level and add, as necessary.
