See Top-Post Battery: Disconnecting the Battery- Gasoline/Diesel Vehicles on page 1-4.
2.
Raise the hood and remove the reservoir cap.
See following WARNING.
WARNING
• Coolant reservoir and radiator are pressurized. Remove caps slowly to relieve pressure.
• Hot! Coolant system is pressurized. Do not remove radiator cap while engine is hot.
3.
Place a large drain pan under the radiator and engine drain plugs.
4.
Turn the drain valve at the radiator counterclockwise, for one and one-half turns only, to drain coolant from
radiator.
See following NOTE.
NOTE:
The radiator drain valve does not have a drain
stop
position. It can be removed from the radiator if turned
more than one and one-half rotations.
5.
Turn the drain valve on the engine counterclockwise to drain coolant
.
6.
Remove the engine block coolant plug from the top rear of engine
.
See following
NOTE.
NOTE:
Removing the block plug allows air to escape during the fill process without forming an air lock to coolant flow.
7.
Check the hoses and clamps for looseness or damage. Replace if necessary.
8.
Check the radiator for leaks or severe coil damage. Replace the radiator if damage has created a leak, or has
caused flow restriction from crushed coils.
9.
Close both drain valves but leave the engine block coolant plug open.
10.
Fill the cooling system with an appropriate coolant mixture at the reservoir. Allow the coolant to fill until it reaches
the hole for the engine block coolant plug.
