Thanksgiving is one of the busiest travel stretches of the year, and if you are leaving Moses Lake for the holiday, your car is about to log more highway miles in a few days than it usually sees in weeks. The smartest move is a simple one: do a pre-trip check a week or two before you go. That timing gives you room to fix whatever turns up, without rushing around the day before you pack the car.
Here are five steps that cover the basics, from the ground up.
Step 1: Tires, pressure, and the spare you forgot about
Your tires are the only part of the car touching the road, and cold mornings change how they behave. For every 10-degree drop in temperature, tire pressure falls by about 1 PSI, so tires that were fine in October can be noticeably low by the time you load up the trunk.
Check the pressure when the tires are cold, and set them to the numbers on the driver’s door placard, not the maximum molded into the sidewall. While you are at each wheel, look at the tread. Uneven wear in the middle or on one edge can point to an alignment or suspension issue that is worth knowing about before a long drive.
And do not skip the spare. It is easy to forget for years, then badly missed on the shoulder of the road. Make sure it is inflated and that the jack and lug wrench are actually in the car.
Step 2: Battery and charging system
A battery that starts your car without complaint in mild weather can still fail on the first hard freeze, because cold slows the chemical reaction inside the battery at exactly the moment the engine needs more cranking power. If your battery is more than three years old or cranking has sounded sluggish lately, a load test is quick and tells you where you stand.
While you are under the hood, look at the terminals. White or bluish crust around the posts interferes with the connection, and a loose clamp can cause intermittent starting that is miserable to diagnose in a dark parking lot. A shop can clean and tighten the connections and test the charging system at the same time, so you are not guessing about the alternator.
Step 3: Fluids — oil, coolant, and washer fluid
Three fluids deserve a look before a long trip.
Engine oil: If you are within a few hundred miles of the next change, do it before you leave rather than after you get back. Fresh oil is cheap insurance for an engine that will see steady highway speeds.
Coolant: This one matters most for cold-weather travel. Coolant protects your engine from freezing overnight, and a mixture that is too weak can fail exactly when temperatures drop. A quick test measures the freeze point, so you know the radiator and block are protected on frosty nights.
Washer fluid: Summer formula can freeze in the lines and leave you staring through road spray with no way to clear it. Top up with a fluid rated for freezing temperatures before you head out.
Step 4: Brakes, wipers, and defroster
Listen to your brakes during the week before the trip. Squealing, grinding, or a pedal that feels soft or travels farther than usual all deserve a look before you rely on them at highway speed with a car full of family.
Visibility is the other half of safety. Wiper blades that streak or chatter in light rain will be worse against slush and road spray, and the defroster needs to actually defrost. Run it on a cold morning and make sure the windshield clears evenly, front and rear. If heat or defrost performance seems weak, that can also hint at a cooling-system issue worth checking.
Step 5: Pack smart for the drive
The last step costs nothing but a few minutes with the trunk open.
- Jumper cables or a portable jump starter
- Flashlight with fresh batteries
- Blanket and gloves
- Phone charger, ideally a spare
- Basic first-aid kit
- Water and a few snacks
Check your route the night before and leave with plenty of fuel. Rest stops come and go on rural stretches of highway, and a near-empty tank turns a small delay into a real problem.
