COOLING SYSTEM DRAINING, FILLING AND BLEEDING - HYBRID
Draining
WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is
operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened
slightly. Failure to follow these instructions may result in serious personal injury.
CAUTION: The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated, it must be recycled or disposed of
correctly. Using contaminated coolant may result in damage to the engine or cooling system components.
CAUTION: The engine cooling system is filled with Mazda Premium Engine Coolant. Mixing coolant types degrades the corrosion protection of Mazda
Premium Engine Coolant.
NOTE: The addition of Cooling System Stop Leak Pellets or equivalent meeting Mazda specification darkens Mazda Premium Engine Coolant from
yellow to golden tan.
NOTE: Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.
1. Release the pressure in the cooling system by slowly turning the pressure relief cap one half turn counterclockwise. When the pressure is released,
remove the pressure relief cap.
2. Remove the splash shields.
3. Place a suitable container below the radiator draincock.
-
Open the draincock and allow to drain.
-
Close the draincock after draining.
4. When the coolant is drained, make sure drain plugs are installed and tight.
