Top 5 Essential Vehicle Fluids to Check Before Winter Hits
As winter approaches in Omaha, it’s time to start thinking about how to keep your vehicle running smoothly through the cold months ahead.
Frigid temperatures, icy roads, and harsh conditions can take a toll on your car, but a little preparation goes a long way.
One of the simplest and most effective ways to protect your vehicle is by checking and maintaining its essential fluids.
Here are the top five fluids you should check before winter hits.

1. Engine Oil
2. Antifreeze (Coolant)
3. Transmission Fluid
4. Brake Fluid
5. Windshield Washer Fluid
Bonus Tip: Schedule a Winter Maintenance Check
1. Engine Oil
Your engine oil is your vehicle’s lifeblood. It lubricates the moving parts, keeps the engine cool, and prevents wear and tear. Cold weather thickens oil, making it harder for your engine to turn over and run efficiently.
Tip: Check your oil level and condition. If it’s dark or gritty, it’s time for an oil change. Ask your service advisor whether switching to a winter-grade oil might benefit your vehicle, especially if you drive in subzero temperatures.
2. Antifreeze (Coolant)
Despite the name, antifreeze doesn’t just prevent your engine from freezing — it also keeps it from overheating. The right mixture of antifreeze and water (usually 50/50) ensures your engine maintains a steady temperature no matter how cold it gets outside.
Tip: Pop the hood and check the coolant reservoir. If levels are low or the fluid looks rusty or sludgy, schedule a coolant flush before the first freeze.
3. Transmission Fluid
Transmission fluid keeps your gears shifting smoothly — and when it’s low or old, you could experience hard shifting, slipping, or even transmission damage. Cold weather can thicken this fluid, making it work harder than usual.
Tip: Check your transmission fluid regularly and make sure it’s bright red and free of debris. If it’s dark or smells burnt, have it replaced.
4. Brake Fluid
When the roads are slick, your brakes are your best friend. Brake fluid plays a major role in how well your braking system responds, especially in freezing temperatures where moisture buildup can cause issues.
Tip: Check your brake fluid level and color. It should be clear or slightly yellow. If it’s dark or dirty, it’s time for a flush to ensure safe stopping power all winter long.
5. Windshield Washer Fluid
This one’s easy to overlook — until you’re driving through slush and grime on I-80 with no visibility. Winter-specific washer fluids are formulated to resist freezing and help break down ice and salt buildup on your windshield.
Tip: Top off your washer reservoir with a winter-grade fluid and make sure your wipers are in good shape for the season.
