Cooling System Bleeding: Mazda6
CAUTION:
The engine has aluminum parts that can be damaged by alcohol or methanol antifreeze. Do not use alcohol or methanol in the cooling system. Use only ethylene-glycol-based coolant.
CAUTION:
Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will reduce the coolant's effectiveness.
CAUTION:
Engine coolant damages paint. If engine coolant does get on a painted surface, rinse it off quickly.
NOTE:
For proper antifreeze-to-water mixture percentages, see appropriate COOLING SYSTEM - MECHANICAL article in ENGINES.
- Slowly pour the coolant into the radiator up to the coolant filler port. See Fig 1.
- Fill the engine coolant into the coolant reservoir tank up to the "F" mark on the coolant reservoir tank.
- Tighten the cooling system cap.
- Start the engine and idle it until the cooling fan operates.
- After engine warms up, perform the following steps:
- Run the engine at 2500 RPM for 5 minutes.
- Run the engine at 4500 RPM for 5 seconds , then idle. Repeat 5 times.
- Idle the engine for one minute.
- Stop the engine and wait until it is cool.
- Inspect the coolant level. If it is low, repeat steps 1- 6 on 2.3L models or steps 2- 6 on 3.0L models.
- Install the cooling system cap.
- Inspect for coolant leakage.
CAUTION:
If the coolant temperature becomes too high, stop the engine to prevent it from overheating.
