Warning: Only technicians who have been trained in High
Voltage Awareness are permitted to perform this procedure. Proper
personal protective equipment (PPE) and insulating HV gloves with a
minimum rating of class 00 (500V) must be worn any time a high
voltage cable is handled. Refer to Tech Note TN-15-92-003, "High
Voltage Awareness Care Points" for additional safety information.
Warning: To avoid personal injury, eye protection must be
worn while using compressed air.

(torque 6.5 Nm).
- Remove the bolt that secures the ground strap to the charger
casing (torque 6.5 Nm).
- Position the ground strap aside.
- Clamp both hoses as close to the charger as possible to minimize
coolant loss. Release the hose clips (x2).
Note: Place suitable absorbent material
around the affected area to absorb any possible fluid
spillage.
Caution: Plug component open ports and disconnected
hoses to prevent coolant loss.
- Disconnect both coolant hoses, tilt the charger ports upward,
and plug immediately.
- Remove the charger.
- If the charger is being shipped or stored, allow the coolant to
drain from the charger, then use compressed air lightly to blow out
any remaining coolant.
Caution: Do not exceed 25 PSI when using compressed
air to blow out any remaining coolant.
Installation
