Thank you for choosing SPARKLING MACHINERY.
The 894449-6450 oil cooler housing cover is cast from high-grade aluminum alloy, offering excellent thermal conductivity, structural rigidity, and resistance to corrosion from engine coolant additives. It seals the oil cooler core against the engine block, ensuring clean heat exchange between hot engine oil and circulating coolant without cross-contamination. Replacing a cracked, warped, or pitted oil cooler cover restores proper engine oil cooling efficiency, protects against internal oil-coolant mixing, and preserves engine lubrication integrity.

FAQ
What are the primary warning signs that an engine oil cooler cover is failing?
The most noticeable warning signs are engine oil mixing into the radiator/coolant expansion tank (appearing as a milky brown sludge), coolant contaminating the oil sump (causing milky white engine oil on the dipstick), or active oil/coolant leaks dripping from the housing mating seams on the side of the engine block.
