housing, you need not remove cover because
there are no components inside the reservoir.

cover.

2. Inspect cover for cracks or holes, replace as

necessary.

3. If cover is in good condition and to be reused, clean

off all gasket residue and wipe clean, then set
cover and four cap screws aside for final
assembly.
