Coolant replacement


1. Close radiator pipe and engine drain cocks and torque the radiator cock to 12ft-lb (170kg-cm) and the engine cock to 9ft-lb (130kg-cm).
2. Connect service hoses.

b. Suspend the opposite end of the hose connected to the radiator to the hood stay.
c. Suspend the opposite end of the hose connected to the heater air bleeder valve to the windshield washer tube. NOTE: Do not close off or pinch any of the tubes.
3. Refill with coolant
a. Open the water inlet, radiator and heater air bleeder valves about three turns.
b. Pour the coolant into the the water filler.
c. When the coolant begins to come out of the engine air bleeder valve, stop pouring and close the air drain valve.
d. Again, pour coolant into the water filler hole until it is full.
e. Check that the coolant levels in the suspended tubes come up to the level of the water filler nozzle. NOTE: If the coolant level in either tube does not come up to filler nozzle level, check the tube for folds or obstructions and repeat steps (d) and (e) above.
f. Close the radiator and heater air bleeder.
g. Disconnect the service hoses. NOTE: When removing the hoses, place a rag beneath the valve to catch any dripping coolant.
h. Fasten the radiator cap (water filler cap) to the first stop point. NOTE: Do not tighten the radiator cap completely (to the second stop point).
i. Start the engine and run at fast idle for about 3 minutes, and then turn it off. If the level of the coolant in the radiator filler hole falls add coolant as before and repeat steps (h) and (i) above.
