Electra-Cool Engine Oil Cooler Kit -8AN

The Electra-Cool Engine Oil Cooler Kit -8AN by DERALE is an essential upgrade for any vehicle experiencing elevated oil temperatures during sustained driving, towing, or high-performance operation. As a mechanic, you know that engine oil degrades rapidly above 220°F, losing viscosity and protective properties that keep internal components safe from accelerated wear. This kit addresses that critical thermal management issue by circulating oil through a dedicated cooling circuit, maintaining optimal operating temperatures and extending engine longevity. Whether you're running a modified street engine, towing heavy loads, or pushing your vehicle hard at the track, oil cooler installation is one of the highest-ROI modifications available.

The -8AN designation refers to the AN8 hose fittings that connect the cooler to your engine's oil system, providing secure, leak-free connections without requiring professional hose fabrication. DERALE's core-and-plate aluminum construction maximizes heat dissipation while remaining compact enough to fit in tight engine bays—the 14.9 x 6.6 x 19.1-inch footprint clears most engine compartments without requiring frame rails or suspension modifications. The design includes thermostatic bypass valving that prevents oil from cooling excessively during cold starts, ensuring proper viscosity flow and protecting against thermal shock to internal bearings. At 13.8 lbs, the complete assembly is lightweight enough to avoid adding significant unsprung mass while still providing the thermal capacity needed for serious cooling demand.

This kit benefits anyone running forced induction, extended highway towing, or engines modified for higher power output—situations where stock cooling capacity becomes the limiting factor in reliability. Installation involves tapping your engine block or pan for oil feed/return lines, then routing AN8 hoses to the cooler and back; most applications require drilling and adapter fittings specific to your engine platform. Before purchasing, confirm that your engine block accepts oil cooler sandwich adapters or that your pan has provisions for a feed line—older vehicles may require custom fabrication. Proper plumbing with quality hoses and clamps ensures years of trouble-free operation and consistently lower oil temperatures that maximize engine protection and performance.
