Oil filter (Mazda Capella GD)

The replaceable filter element is released using a filter key, which can be purchased at a specialized auto parts store (figure 122). If you don't have such a key and the filter needs to be replaced, you can insert a screwdriver through the side of the filter and unscrew it, using the handle as a lever. The filter should be changed every 12,000 km or if the engine is overhauled.



After unscrewing the filter, thoroughly clean the seat on the block and lubricate the seal of the new filter with engine oil. When installing the filter, observe the following:

• For a standard engine, screw the new filter on until the O-ring is seated, and from this position, tighten it 2/3 of a turn. Do this by hand only, without using any tools.
• For DOHC and diesel engines, screw the filter until it contacts the rubber ring and from this position, use a filter wrench to tighten it by 1 ^1/6 turnover.

Start the engine and let it run for a while. Check for rust stains on the filter connection. Check the condition of the engine oil and top up the missing amount.
