Coolant: Service and Repair

ENGINE COOLANT

Changing Engine Coolant

WARNING:
-

To avoid being scalded, never change the coolant when the engine is hot.

-

Wrap a thick cloth around the cap to carefully remove the cap. First, turn the cap a quarter of a turn to release any built-up pressure,
then push down and turn the cap all the way to remove it.

DRAINING ENGINE COOLANT
1. Turn ignition switch ON and set temperature control lever all the way to HOT position or the highest temperature position. Wait 10 seconds and

turn ignition switch OFF.

2. Remove the engine front undercover using power tool.

3. Open the radiator drain plug at the bottom of the radiator, and remove the reservoir cap. This is the only step required when partially draining the

cooling system (radiator only).

CAUTION:
Do not to allow the coolant to contact the drive belts.
4. When draining all of the coolant in the system for engine removal or repair, it is necessary to drain the cylinder block.
Remove the cylinder block drain plugs (A), (B), (C), (D) and block heater if equipped, to drain the cylinder block as shown.

NOTE:
For Canada, the (D) cylinder block drain plug as shown, is not a cylinder block drain plug but a block heater.

5. Remove the reservoir tank to drain the engine coolant, then clean the reservoir tank before installing it.
6. Check the drained coolant for contaminants such as rust, corrosion or discoloration.
If the coolant is contaminated, flush the engine cooling system. Follow the "Flushing Cooling System" procedure.
