Designed for a wide range of GM vehicles equipped with select 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L V8 engines, this standard-volume engine oil pump supports the engine lubrication system by circulating oil to critical components such as bearings, camshafts, and pistons.

Verify the reference numbers and exact engine application before ordering, as fitment varies by model, year, and engine configuration.

Product Features

Broad Compatibility Across Select GM V8 Applications

Designed for numerous Chevrolet and GMC vehicles, including select Avalanche, Camaro, Corvette, Express, Silverado, Tahoe, Suburban, Sierra, Savana, Trailblazer, Envoy, Yukon, and Yukon XL models. It may also fit specified Hummer, Pontiac, Cadillac, Saab, and Buick vehicles equipped with matching V8 engine configurations. Check the complete application details before purchase.

Standard-Volume Oil Circulation for Engine Lubrication

Designed to circulate engine oil through the lubrication system, helping supply essential components such as bearings, camshafts, and pistons. Proper oil circulation helps reduce friction and wear during engine operation.

Aluminum Housing for Heat and Corrosion Resistance

The aluminum housing is designed to resist corrosion, tolerate elevated operating temperatures, and maintain its shape during extended use. These properties support dependable operation within the engine lubrication system.

Replacement Kit with Washers and Installation Accessories

The kit includes one standard-volume engine oil pump and two washers, along with the stated installation accessories. Replacing a worn or failing oil pump may help address lubrication-related concerns, but the cause of low oil pressure or engine noise should be diagnosed before replacement.
