Product Details

HT-2270 is an engine valve lifter used in hydraulic roller valvetrain systems where consistent lifter operation is critical to valve timing and engine performance. This part is listed across many 1993-2011 applications, including Chevrolet Impala, Chevrolet Malibu, Pontiac Grand Prix, Buick Regal, and Chevrolet S10 models. It is also listed for other GM platforms such as the Saturn Vue, Pontiac Torrent, and Chevrolet Equinox.

This part cross-references 362270 and HL2270 for the same application. Verify engine code and valvetrain configuration before ordering, especially on 2007-2008 Chevrolet Impala applications that require a non-AFM lifter per GM Bulletin #13-06-01-002.

What It Helps Fix

• Ticking or tapping noise from a worn hydraulic roller lifter
• Valve train instability caused by lifter wear or internal leakage
• Rough idle related to inconsistent valve actuation
• Misfire concerns tied to poor lifter operation
• Loss of proper valve lift control in hydraulic roller systems

Installation Notes

Confirm the engine uses hydraulic roller lifters before installation. Match the part number HT-2270 to the exact year, make, model, and engine configuration, since fitment varies by application. On 2007-2008 Chevrolet Impala models, use the non-active fuel management lifter requirement noted in the fitment data. Clean oil passages and inspect related valvetrain components during service.
