Installation Notes

Ensure the engine is cool and turned off. Position an oil drain pan under the filter housing.
Unscrew the oil filter housing cap using the appropriate wrench. This will expose the old filter element.
Carefully remove the old filter element and any old O-rings or seals from the cap and housing.
Wipe the housing and cap clean with a lint-free cloth.
Install the new O-rings (if included) onto the cap and lubricate them with a thin film of clean engine oil.
Insert the new oil filter element into the housing, ensuring it is properly seated.
Screw the housing cap back on and tighten it to the torque specified by the manufacturer. Do not overtighten.
After refilling the engine with oil, run the engine for a few minutes and check for any leaks around the filter housing.

Troubleshooting & FAQ

How do I know if this oil filter element will fit my engine?

This filter is specifically for Mercury/Mercruiser 2.0L I4 diesel engines (115–170 HP, 2008+). The most reliable way to confirm fitment is to check your engine's serial number against the ranges listed in the compatibility table above. Cross-referencing your old filter's part number with 35-879312041 is also a good verification step.

How often should I replace my diesel engine's oil filter?

It is best to follow the service interval recommendations in your engine’s owner manual. Generally, the oil filter should be replaced with every oil change, typically every 100 hours of operation or annually, whichever comes first.

What are the signs of a clogged or failing oil filter?

Common symptoms include low oil pressure readings, a noticeable drop in engine performance, or the engine oil appearing excessively dirty shortly after a change. In severe cases, the filter's bypass valve may open, allowing unfiltered oil to circulate, which can cause accelerated engine wear.

Is this a spin-on filter or an internal cartridge?

This is an internal cartridge-style filter element. It fits inside a permanent filter housing on the engine block, rather than being a self-contained, spin-on canister.

Does this filter come with new O-rings or seals?

The package contains only the filter element itself. O-rings and seals for the filter housing are typically sold separately or as part of a more comprehensive service kit. Always inspect your existing seals and replace them if they show signs of wear or damage.

What's the difference between this filter and the OEM version?

This listing is an aftermarket replacement (not OEM). It is built to OEM-level specifications with comparable materials, offering the same fit and filtration performance as the original part. Our parts are manufactured in an ISO 9002 certified facility and are batch-inspected for quality and consistency.

What are your shipping speed and cost?

We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free to most locations; expedited options at an additional cost will appear at checkout where available.

What is the warranty and return policy?

This product is covered by a 1-year warranty against manufacturing defects under normal use. If you encounter any issues, please contact our support team with your order details.
