Memorial Day Trailer Check: 2018-2024 Buick Enclave Checklist

Hitch, wiring, brake controller and mirror checks. Applied to a 2018-2024 Enclave, here is what that looks like.

Cooling System

Watch for a heater that blows cool at idle and warm at speed. 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.

Brakes

Watch for uneven pad thickness side to side when you pull a wheel. Inspect at every tire rotation. Most GM trucks and SUVs go 30,000 to 60,000 miles on front pads depending on how they are used, and towing cuts that hard.

Exhaust and Emissions

Watch for a diesel that regenerates far more often than it used to. Not scheduled. Converters are warranted separately under federal emissions rules, so check coverage before you buy.

Sensors, Cameras and Driver Assistance

Watch for a backup camera image that flickers, goes blue, or shows lines. TPMS sensor batteries typically last seven to ten years and are commonly replaced as a set during a tire change.

The Short Version

Radiators: Engine, tow package and rear-A/C content all change the radiator and hose part numbers. Have the VIN ready.
Brake pads: Front and rear pads are almost never the same part, and heavy duty, tow and performance brake packages use different calipers and rotors than the base vehicle.
Catalytic converters: Emissions equipment varies by state of original sale on some model years.
Park assist sensors: Painted park assist sensors are ordered in primer and painted to your code. Confirm your paint code before ordering.

If you are not sure which version fits your build, send us the VIN and we will confirm before anything ships. Shop our Buick OEM parts catalog or search for Enclave parts.
