Common Chevrolet problems
AFM/DFM lifter failure (5.3L/6.2L V8)
Active Fuel Management lifters can collapse, causing ticking and misfires. Many owners disable AFM via tune and install non-AFM lifters.
8L90 transmission shudder
Torque converter shudder around 35–55 mph. GM bulletin recommends Mobil 1 ATF flush.
Dexcos coolant intrusion
Older Dex-Cool can react with worn intake gaskets, leading to coolant leaks.
Chevrolet maintenance tips
- Flush the 8L90 transmission with Mobil 1 ATF at 45,000 miles.
- Consider an AFM disabler on 5.3L and 6.2L V8 engines to prevent lifter failure.
- Inspect the rear differential fluid at 50,000 miles — GM trucks run a small fluid capacity.
Frequently asked questions
Are Chevy Silverados reliable?
Yes — the Silverado 1500 with the 5.3L or 6.2L V8 commonly exceeds 250,000 miles. The biggest weakness is AFM lifter failure, which can be mitigated with a disabler.
What is AFM and why disable it?
Active Fuel Management deactivates cylinders to save fuel. It puts unusual stress on lifters and is a leading cause of engine failure on GM V8s built between 2007 and 2020.
