Radiator and expansion tank — removal and installation (Mazda Capella GF)

Caution: Do not begin this work until the engine has cooled down.

Expansion tank

1. Disconnect the hose from the expansion tank neck that connects it to the radiator. Remove the tank mounting bolts and remove it from the vehicle (figure 5.1, a, b). Drain the liquid from the tank into a suitable container. Inspect the tank for cracks and other damage.

Radiator

2. Disconnect the negative cable from the battery.

Caution: If your vehicle's audio system is equipped with anti-theft protection, make sure you have the unlock code before disconnecting the battery.

3. Drain the coolant into a clean container.

4. Remove the fans (see paragraph 4).

5. Disconnect the expansion tank hose from the radiator neck. Loosen the upper and lower radiator hose clamps and disconnect the hoses (figure 5.5).





6. On models with automatic transmission, disconnect the oil cooler hoses from the radiator (figure 5.6). Place a container underneath to collect the transmission fluid and plug the openings to prevent dirt from entering the system.



7. Remove the radiator mounting bolts (one on each side) and pull the radiator up (figure 5.7).

Note: The radiator is mounted on the support frame from below without bolts.

8. After removing the radiator, it can be checked for leaks, damage and blockage of the core tubes. If repairs are necessary, take it to a service station or a specialized workshop, as repairs require specialized equipment and technology.

9. External contamination of the core by insects, leaves and other dirt can be removed with a soft brush and compressed air. Do not attempt to repair bent grill ribs yourself.

12. Start the engine and check for leaks. Warm up the engine to normal operating temperature when both radiator hoses are hot. Check the coolant level and top up if necessary.

13. On models with automatic transmission, check the transmission fluid level and top up as needed.
