Cooling System Draining, Filling And Bleeding: Draining
WARNING: This page is about a different car, the 2003 Mazda Tribute, 2002 Mazda Tribute, and 2001 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
- To avoid personal injury, do not unscrew the coolant pressure relief cap while engine is operating or 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 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.
NOTE:
- About 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.
- 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.
- Place a suitable container below the radiator drain-cock.
- Open the draincock and allow to drain.
- Close the radiator draincock when finished.
