You’re loaded up for Banff. Cooler in the trunk, kids in the back, maybe a kayak on the roof. Then halfway up the Bow Valley Parkway your temperature gauge starts climbing.
That’s the version of a road trip nobody wants. A few minutes of checking the right stuff in your driveway before you leave can save you a tow off Highway 1 — or worse, an ER trip.
Here’s the list. It’s ordered roughly by what fails most often on summer trips, not alphabetically.
1. Tire pressure (and the spare)
Heat builds tire pressure. A tire set to 32 psi in your cool garage at 7 AM can read 38 psi after two hours on hot asphalt. That’s normal. What’s not normal is leaving Calgary with one tire already 5 psi low — that one runs even hotter, the rubber breaks down faster, and that’s how blowouts happen at highway speed.
Check pressure cold, before you leave. Use the number on the door jamb sticker (driver’s side), not the number on the sidewall — the sidewall number is the maximum, not the recommended.
And check the spare. We pull cars in all the time where the spare’s been sitting at 15 psi for four years and the owner had no idea. More on tire services here.
2. Coolant level and condition
This is the one that strands people on mountain passes. Climbing the Trans-Canada toward Lake Louise asks more of your cooling system than any city driving does — long sustained climb, hot weather, often with the AC on and a packed vehicle.
Pop the hood when the engine is cold and look at the coolant reservoir. The level should be between the MIN and MAX lines. If it’s low, top it up with the correct coolant for your vehicle (the manual tells you which type). If the coolant in the reservoir looks brown, sludgy, or has bits floating in it, don’t road trip on it — book a cooling system check first.
3. Oil level (and when it was last changed)
Quick dipstick check. Pull it, wipe it, put it back in, pull it again. Level should be between the two marks. If it’s at or below the lower mark, top it up.
If you can’t remember when it was last changed and you’re heading out for a 1,500-km round trip to Jasper, just get it changed before you leave. New oil is cheap insurance, and you don’t want a dipstick reading “low” 600 km from home.
4. Brakes — especially before the mountains
Mountain driving is harder on brakes than city driving by a long way. Long descents off Sunwapta Pass or the Highwood Pass mean sustained braking, which heats pads and rotors, which can warp rotors or boil brake fluid if everything is already marginal.
Symptoms to take seriously before you leave:
- Squealing on light braking (pad wear indicators)
- Steering wheel shake when you brake from highway speed (warped rotors)
- Soft pedal that goes further than it used to (fluid or air in the lines)
Any of those mean call us before you leave the city, not after.
5. Battery age
Heat kills batteries faster than cold does, even though cold gets the blame because that’s when failures actually show up. A battery that’s already 4–5 years old can fail in 35°C parking-lot heat with no warning. Slow crank when you start? Dim dash lights? That battery probably isn’t making it back from Drumheller.
Most shops can load-test a battery in five minutes. If you’re not sure of yours, get it tested.
6. A/C — actually running cold
There’s a difference between AC that blows cold air for ten minutes and AC that keeps a packed minivan with five people in it cold for six hours in 30°C heat. If yours already feels weak in city driving, it’s going to fold completely on the highway.
We’re not pushing the seasonal recharge promo here — just saying if it’s not cold, it’s worth checking before you commit to a long drive.
7. Wiper blades and washer fluid
Sounds minor. Isn’t. Summer storms in the foothills can dump rain hard enough that wipers go from “fine” to “useless” in five seconds if the blades are old. Bug splatter alone will obscure your windshield within 100 km of mountain driving.
Replace blades if they smear or chatter. Top the washer reservoir all the way up. Cheap to do, easy to forget.
8. Emergency kit in the trunk
Not a maintenance item exactly, but worth a 60-second check:
- Jumper cables or a portable jump pack
- A tire-pressure gauge
- A basic first-aid kit
- A bottle or two of water
- A phone charger that actually fits your phone
Cell service drops off in the mountains. AMA response times go up. Being able to handle a small thing yourself can be the difference between a 30-minute fix and a 4-hour wait.

FAQ
How far before a road trip should I get my car checked?
A week to ten days, ideally. That leaves time to fix anything that turns up without rushing parts or rebooking the trip. Don’t show up the day before you leave for Jasper and ask for new brakes — that’s how vacations turn into stress.
Do I need to do anything different for mountain driving vs flat highway driving?
Yes. Mountain driving stresses brakes (long descents), cooling (long climbs), and tires (heat) more than flat highway does. The pre-trip list above is built around those three failure points specifically.
Is the spare tire really that important?
Yes, especially if you’re driving anywhere remote in the Rockies. A spare at proper pressure can be the difference between changing it yourself in 15 minutes and waiting two hours for a tow truck.
