Inspect the lock plate for damage.

HINT:
^ If the sides of the lock plate groove are deformed, reassembly of the tank will be impossible.
^ Therefore, first correct any deformation with pliers or similar object. Water leakage will result if the bottom of the lock plate groove is damaged or dented. Therefore, repair or replace if necessary.

NOTICE: The radiator can only be recaulked 2 times. After the 2nd time, the radiator core must be replaced.

3. INSTALL NEW O-RINGS AND TANKS
