Getting Your GMC Ready for Winter in Central Ohio: A Service Checklist

Winterizing your GMC doesn't have to be complicated. Here's what to prioritize before Central Ohio's cold weather really settles in for the season, one system at a time.

Central Ohio weather doesn't wait around. One week you're raking leaves in a light jacket, and the next you're scraping frost off the windshield before sunrise.

Is your GMC actually ready for that switch, or are you just hoping for the best? At Twins Buick GMC in Columbus, going through a full winter car service checklist every fall is one of the easiest ways to avoid a bad surprise once the temperature drops for good.

Cold weather is hard on batteries. The colder it gets, the more power it takes to start your engine, and a battery that's already marginal in the fall can fail outright once overnight lows hit the 20s.

Have a technician run a load test before winter sets in. If it's borderline, battery replacement now is a lot cheaper than a tow later, and it beats getting stranded on a cold, dark morning.

Tire pressure drops as the temperature does, roughly 1 PSI for every 10-degree change. That means a tire that read fine in October can be noticeably low by December.

Low pressure hurts both grip and fuel economy, so it's worth checking monthly once winter arrives, not just once before the season starts.

Oil thickens as temperatures drop, and thick oil doesn't flow well through a cold engine at startup. That extra strain is one of the more common causes of winter engine wear.

A fresh oil change with the manufacturer-recommended weight keeps everything moving the way it should on frosty mornings, right from the first turn of the key.

Tire tread below about 4/32 of an inch starts losing its ability to grip snow, slush, and ice. Once that happens, stopping distances grow fast on wet or icy pavement.

A quick tread check before the first snowfall tells you whether your current tires will hold up through the season, or whether it's time to start planning for new ones.

A weak defroster leaves you driving with a fogged or icy windshield right when visibility matters most, and that's a safety issue, not just an inconvenience.

If yours is slow to clear the glass, have it checked along with your wiper blades and washer fluid. All three work together to keep your view of the road clear.

Central Ohio crews rely heavily on road salt once the roads turn icy, and that salt does more than clear the pavement. It also accelerates rust on brake lines, exhaust components, and the undercarriage.

Rinsing the underside periodically through the season and staying ahead of brake inspections helps protect those parts from damage that builds up gradually and quietly.

Antifreeze does more work in winter than most drivers realize. A weak coolant mix can freeze and crack a block during a hard cold snap, so it's worth confirming the ratio before temperatures fall.

While a technician is under the hood, it's an easy time to check belts and hoses too. They can fail any time of year, but a failure in freezing weather turns a simple fix into a much colder problem.

Standard wiper blades can struggle to clear ice and packed snow the way winter blades do. If yours are worn or brittle from a summer of sun, now's the time to replace them.

Washer fluid matters just as much. A winter-rated formula resists freezing in the lines, so a quick top-off before the first hard freeze keeps your windshield clear when you need it most.
