Good To Know

Q: How do I know if my oil cooler is failing? A: Common symptoms include oil puddles under the engine, milky coolant in the radiator reservoir, or elevated oil temperature readings. If oil and coolant mix, flush both systems completely before replacing the unit.

Q: Are replacement O-rings or gaskets included with this cooler? A: Please check the packaging contents closely; it is standard practice to use brand-new, fresh seals during installation to ensure a perfect, leak-free seal against the engine block.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
