Remove the engine front undercover using power tool. Refer to FRONT BUMPER: REMOVAL AND INSTALLATION
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 allow the coolant to contact the drive belts.
- Perform this step when engine is cold.
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 in illustration.

CAUTION: Do not reuse copper sealing washers.

NOTE: For Canada, the (D) cylinder block drain plug as shown in illustration, is not a cylinder block drain plug but a block heater.
Remove the reservoir tank to drain the engine coolant, then clean the reservoir tank before installing it.
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.
