Texas summer travel is hard on vehicles. Between triple digit heat, long highway stretches, and a loaded vehicle, small problems become roadside problems in a hurry. Before you point the truck toward the coast, Big Bend, or a family trip out of state, spend an hour on the items below.
Here is the pre-trip service checklist our technicians at Covert Chevrolet Bastrop run through, and why each item matters more in August than it does in February.
1. Cooling System and Coolant Level
Heat is the number one cause of summer breakdowns. Your cooling system has to shed engine heat while the outside air is already over 100 degrees, and it has almost no margin left when something is marginal.
- Check coolant level and condition, not just level
- Inspect hoses for soft spots, swelling, or cracking
- Look for crusty white or green residue near clamps and the radiator, which signals a slow leak
- Verify the radiator fan cycles correctly
If your coolant has never been flushed and your vehicle has over 100,000 miles, get it done before the trip, not after.
2. Tires, Including the Spare
Hot pavement plus underinflated tires plus a loaded vehicle is how blowouts happen. Check pressures when the tires are cold, first thing in the morning before you drive, and set them to the number on the driver door jamb sticker, not the number molded into the sidewall.
Check tread depth with a penny or a quarter, and look for uneven wear that points to an alignment problem. Then check the spare. Most people never do, and a flat spare turns a 30 minute stop into a tow.
3. Air Conditioning Performance
An A/C system that feels “okay” in May will feel terrible in August with four people and a full cargo area. If the air coming out of the vents is not noticeably cold within a minute or two of startup, get it checked. Low refrigerant is often a symptom of a leak, and topping it off without finding the leak just buys you a few weeks.
4. Brakes
Mountain grades and heavy traffic both punish brakes. If you hear grinding, feel a pulsation through the pedal, or notice the pedal traveling farther than it used to, have the system inspected before you go. Brake fluid also absorbs moisture over time, which lowers its boiling point exactly when you need it most.
5. Oil, Filters, and Fluids
If your oil life monitor is under 30 percent, change it before the trip rather than trying to find a shop in an unfamiliar town. While you are there, have the cabin air filter and engine air filter checked. Central Texas dust and cedar pollen load them up faster than the maintenance schedule assumes.
6. Battery
Heat kills batteries faster than cold does. High temperatures accelerate internal corrosion, and the failure usually shows up on the first cool morning after summer. A load test takes a few minutes and tells you whether you have a year left or a week.
7. Wipers, Lights, and Washer Fluid
Summer in Texas means sudden downpours and a windshield covered in insects. Replace wipers that streak, top off washer fluid, and walk around the vehicle to confirm every exterior light works. It is a five minute check that prevents a ticket and improves visibility.
8. A Summer Emergency Kit
Every item above is preventive. This one is what you carry in case prevention was not enough, and in a Texas August the difference matters more than it does anywhere else.
- More drinking water than you think you need, for every person in the vehicle
- A portable jump pack, which works when there is nobody in the next parking space
- A tire plug kit and a 12-volt compressor
- A phone charger and a backup battery
- A folding sunshade, so a roadside stop is survivable rather than dangerous
Heat is the reason this list looks different here. A breakdown on a shaded interstate in October is an inconvenience. The same breakdown on Highway 71 at two in the afternoon in August, with children in the back, is a genuine safety problem, and the shoulder offers no shade at all.
If you are towing, add a spare set of trailer bearings and a lug wrench that actually fits the trailer’s wheels rather than the vehicle’s.
Frequently Asked Questions
How far ahead of a trip should I schedule service?
One to two weeks. That leaves room to order a part if the inspection turns something up, and it lets you drive the vehicle for a few days afterward to confirm everything is right.
Do I need to use a Chevy dealership for maintenance?
You are not required to, but a GM-certified technician knows the specific service bulletins and known issues for your model and uses Genuine GM parts designed for it. That matters most on newer vehicles still under warranty.
What if something fails on the road?
Most new Chevrolet vehicles include roadside assistance for the duration of the powertrain warranty period. Save the number in your phone before you leave.
What should I do if my vehicle overheats on the highway?
Pull over as soon as it is safe, shut the engine off, and let it cool before opening anything. Do not open a hot radiator cap. Continuing to drive an overheating engine is what turns a hose repair into a head gasket or a replacement engine.
