Inspect For PHEV Coolant Leakage
WARNING: This page is about a different variant/trim than selected.
WARNING:
<<High voltage>>
- Always observe the following thoroughly to ensure safety when inspecting or removing/installing parts in the motor compartment. Otherwise, the high voltage circuit may operate on the vehicle regardless of whether or not the main power is switched OFF or ON (READY off or on). If this occurs, it could cause electrical shock and result in serious injury or, in the worst case, death.
- Do not perform normal charging or quick charging
- Access connected vehicle maintenance mode (MyMazda App connected vehicle)
- Cancel climate control timer
WARNING:
- Always observe the following thoroughly to ensure safety when inspecting or removing/installing parts in the motor compartment. Otherwise, the cooling fan may operate on the vehicle regardless of whether or not the main power is switched OFF or ON (READY off or on). If this occurs, it could cause injuries such as lacerations and from getting caught in the cooling fan.
- Do not perform normal charging or quick charging
- Access connected vehicle maintenance mode (MyMazda App connected vehicle)
- Cancel climate control timer
- The EV system is hot immediately after driving and charging, and can cause severe burns. Turn off the EV
- system and wait until it is cool before performing the servicing.
- If the PHEV cooling system cap is removed while the PHEV cooling system is hot, hot coolant may be ejected, causing severe burns or injury. Perform the removal of the PHEV cooling system cap when the PHEV cooling system is cool.
- When removing the PHEV cooling system cap, cover the PHEV cooling system cap with a clean cloth and remove it slowly.
NOTE:
- Perform the procedure with the PHEV cooling system cap removed.
- Install the radiator cap tester to the filling port.
- Apply pressure using the radiator cap tester.
Coolant leakage inspection pressure
122.6 kPa {1.148 kgf/cm2, 16.33 psi} [1 min]
- When pressurizing the radiator, verify that the pressure is maintained.
- If the pressure decreases, repair or replace the location where water is leaking because water leakage can be considered.
