Listed for the 2019β2022 Buick, Cadillac, Chevrolet and GMC with the 2.0L engine. Check your year, model and trim against the title before you order.
What it does
The cylinder head holds the valves and forms the top of the combustion chamber. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Use new head bolts if your engine calls for torque-to-yield bolts, and torque in the correct sequence.
- Head gasket: Always new with a head.
- Coolant and oil: Refill both after the job.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
