Spring Detail and Trim Refresh for Your 2015-2020 GMC Yukon

Moldings, emblems, mats and liners after a hard winter. Applied to a 2015-2020 Yukon, here is what that looks like.

Body and Exterior

Watch for a mirror that shakes at highway speed after a folding motor fails. Not a scheduled item. These are damage and failure replacements.

Cooling System

Watch for crusty orange residue around a hose clamp or the surge tank seam. GM’s long-life coolant is generally rated for 5 years or 150,000 miles on the first fill and 5 years or 100,000 miles after that. Hoses and the surge tank should be inspected annually once past 80,000 miles.

Filters and Fluids

Watch for a slight hesitation on hard acceleration with a dirty air 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.

Electrical and Charging

Watch for a slow crank on the first cold morning of the year. Batteries in Texas heat routinely give up between three and five years. Test annually after year three, before the first cold snap.

The Short Version

Mirrors: Trim level changes almost every exterior part. Take a photo of the connector on the part you are replacing before you order.
Radiators: Engine, tow package and rear-A/C content all change the radiator and hose part numbers. Have the VIN ready.
Oil filters: Engine size and emissions equipment change the filter, and diesel filter kits in particular are not interchangeable across model years.
Batteries: Vehicles with stop-start often use two batteries. Confirm which one you are replacing before ordering.
