Troubleshooting & FAQ

How do I know if this gasket kit will fit my engine?

This kit is designed for MerCruiser CMD QSD 2.0L inline 4-cylinder models (EI and ES) made between 2005 and 2012. Please verify your engine model and year against the compatibility table. The primary OEM part number this replaces is 896332077.

What are the signs of a failing heat exchanger gasket?

Common symptoms include external coolant leaks (visible drips or residue), oil in the coolant (milky appearance in the expansion tank), or coolant in the oil (milky oil on the dipstick). Overheating can also occur if the leak is severe.

Is any special sealant required during installation?

Generally, no. These gaskets are designed to seal on their own. Always install them on clean, dry surfaces. Using additional sealants can sometimes interfere with proper sealing unless specifically recommended in your engine's service manual.

How often should these gaskets be replaced?

There is no fixed replacement interval. Gaskets should be replaced whenever the heat exchanger or oil cooler is removed for service, or if any signs of a leak are detected.

What is the difference between this kit and an OEM part?

This is an aftermarket kit designed to meet or exceed original equipment manufacturer (OEM) specifications for fit, form, and function. It offers a cost-effective solution without compromising on quality or material integrity.

Can this kit be used for both the oil cooler and heat exchanger?

Yes, this gasket and O-ring set is used to seal the connections for the heat exchanger and oil cooler assembly on compatible MerCruiser QSD 2.0L engines.
