FAQ

Q: How can I be sure this oil cooler cover will fit my engine?

A: This part is specifically designed for the Nissan FD33 diesel engine. The OEM part number is 12615-52206. To ensure a correct fit, please locate the part number on your existing oil cooler cover or consult your engine service manual. If your engine is a Nissan FD33, this cover is the correct component for your application.

Q: What are the signs that my oil cooler cover needs to be replaced?

A: The most common sign is an oil leak originating from the front or side of the engine block near the oil filter and cooler assembly. You may also notice engine oil mixing with coolant (appearing as a milky substance in the radiator or oil cap) if the cover or its gasket has failed internally. Overheating oil can also indicate a blockage or failure in the cooling circuit related to the cover.

Q: Do I need to replace the gasket when installing this new cover?

A: Yes, it is strongly recommended to replace the oil cooler cover gasket (or O-ring seal) whenever you remove the cover. Reusing an old, compressed gasket is the most common cause of a post-installation oil leak. We recommend purchasing a new gasket (sold separately) to ensure a secure, leak-free seal.
