Oil Pan & Pump, Oil Cooler

Shop New OEM oil pans, oil pumps, and oil coolers for GM vehicles. Our factory-original internal engine lubrication components are sourced from GM surplus — manufactured to the exact specifications of your engine's lubrication system.

The engine lubrication system — pan, pump, and cooler — works as an integrated unit to maintain oil pressure, temperature, and flow throughout your engine's operating range. OEM components maintain all of the factory design parameters: pump flow rate, pan sump volume, cooler capacity, and oil pressure relief setting.

Engine lubrication system service should be performed with attention to proper torque sequences, correct gasket installation, and system priming before start-up. Verify all part numbers against your engine RPO code before ordering.
