Preparing Your Buick GMC for Winter Driving

snowWhether you have a new or well-loved Buick, proper maintenance is key to a high-performance vehicle in any season. There are many pre-winter maintenance tasks you can accomplish on your own, but why not bring your Buick into our Serra Nashville Chevrolet Buick GMC service center? Our experienced technicians can ensure your vehicle is in top shape and ready to go for the high-traffic holiday season.

De-Icing the Fuel Line

One of the first steps to winterizing your vehicle is adding a de-icer compound to the fuel system. This will ensure excess liquid does not freeze in the fuel line. Mechanics recommend keeping your fuel tank topped off as much as possible in the winter for this same reason. When your fuel tank is below half full, moisture from the air in the tank can condensate and freeze, clogging up the fuel line. The de-icing treatment helps prevent this problem.

Preparing the Cooling System

Although it may seem counterintuitive, the cooling system plays a major role in engine temperature regulation in the winter. To top off the coolant, mechanics will fill the reservoir with a mixture of half antifreeze, half water unless your vehicle’s manual calls for some other ratio.

As part of the coolant system inspection and refill, all hoses are inspected and replaced if cracks are found. Your Serra mechanic will perform a coolant flush and refill the reservoir with a fresh mixture if needed. Proper coolant levels ensure the engine block does not experience any critically high or low temperature variations when the thermometer reaches single digits outside.

Changing the Engine Oil and Filter

If your vehicle was last serviced with a higher viscosity oil such as 20W-50, we will recommend a lower viscosity 5W-30 oil for winter. This type will flow more freely at low temperatures since oil naturally thickens as the temperature drops.

A compatible filter will also be installed so the oil can more easily flow through the microscopic fibers at low temperatures and lubricate all engine parts.

Inspecting Internal Components

Essential components like the battery, timing belt, and transmission will be looked over in detail. We will determine the remaining charge for your battery and discuss with you whether it should be replaced in advance of winter or if it seems capable of lasting through winter. If the charge is low enough that we suspect your vehicle won’t start on a frosty morning, we’ll recommend installing a new battery right away.

Checking Exterior Safety

Some of the exterior components we check include:

  • Tire tread and tire pressure
  • Headlights, taillights, and turn signals
  • Windshield wiper blades
  • Washer fluid level
  • Brake pads and/or discs
