HINT:

Perform the same procedures as the radiator tank.

Check the core plate for damage.

HINT:

• If the sides of the core plate groove are deformed, it is impossible to reassembly the radiator tank. Therefore, first correct any deformation using pliers or a similar tool.
• Water leakage will occur if the bottom of the core plate groove is damaged or dented. Repair or replace it if necessary.
