Pre-Winter Cooling System Check: Chevrolet Silverado EV Edition

Coolant condition, hoses and the surge tank. Applied to a 2024-2026 Silverado EV, here is what that looks like.

Heating and Air Conditioning

Watch for air that only blows on the highest fan setting. Cabin air filter every 12,000 to 15,000 miles, or annually. In North Texas with construction dust and cedar season, annually is the honest number.

Suspension

Watch for a clunk over expansion joints that you feel in the floor more than you hear. Shocks and struts are wear items. Plan on inspection at 50,000 miles and replacement somewhere between 60,000 and 100,000 depending on road quality and load.

Body and Exterior

Watch for a window that drops into the door or moves crookedly. Not a scheduled item. These are damage and failure replacements.

Filters and Fluids

Watch for a diesel that derates or throws a fuel pressure code on a neglected filter. Follow the oil life monitor rather than a fixed mileage. Engine air filter every 30,000 to 45,000 miles. Transmission service intervals vary widely by transmission and by whether you tow.

The Short Version

Cabin air filters: Rear climate content, heated and cooled seats, and tri-zone systems all change the parts list.
Shocks: Trim and package content matters enormously here. Off-road packages, air ride and adaptive or magnetic damping all use different parts than the base vehicle wearing the same model name.
Mirrors: Trim level changes almost every exterior part. Take a photo of the connector on the part you are replacing before you order.
Oil filters: Engine size and emissions equipment change the filter, and diesel filter kits in particular are not interchangeable across model years.
