Everyone remembers winter prep, but summer prep matters just as much. Heat destroys your car differently than frost: overheated engines, dead batteries, tire problems. Planning a coast trip or just want reliability through summer? Here is what to check.
Air Conditioning - Test It Before You Need It
Do not wait for the first 35-degree day to find out the AC is not blowing cold. Turn it on and check. If the air is not cold enough or smells bad, it needs service.
The most common issue is low refrigerant. The system loses gas over time through fittings and hoses. A top-up takes half an hour. But if refrigerant disappears fast, there is a leak that needs finding.
Replace the cabin filter too. A dirty one restricts airflow and causes smells. Change it once a year.
Cooling System - The Engine Needs Something to Cool With
In summer the cooling system works at full load. Check coolant level between min and max marks. Coolant does not just prevent freezing. It raises the boiling point and prevents corrosion.
If coolant is older than two years or has changed color, replace it. Inspect the hoses too. Soft, cracked hoses are a ticking time bomb in heat.
Tires - Heat Increases Pressure
At high temperatures tire air expands and pressure rises. If already at the upper limit, hot pavement can push pressure past safe range. Check in the morning on cold tires and keep at the recommended value.
Inspect condition too. Cracked sidewalls, shallow tread, or uneven wear mean the tire is not safe for long heat-exposed drives. Old tires lose elasticity and are prone to blowouts even with tread left.
Brakes - A Must Before Mountain Passes
If you are heading to the coast, you will likely face some mountain roads. A long descent with weak brakes is dangerous. Check the thickness of the brake pads and discs. If you feel vibrations when braking or the car pulls to one side, get that sorted before you leave.
Battery - Heat Kills It Just Like Cold Does
Many think the battery is only a winter problem, but heat speeds up chemical reactions inside it and shortens its life. If it is three to four years old, get it tested. Better to replace at the shop than get stranded at the beach.
Washer Fluid and Wipers
On a summer drive, especially at night, bugs on the windshield are a serious visibility problem. Fill up the washer fluid reservoir and check that the wipers clean properly. Worn wiper blades smear instead of cleaning.
Spare Tire
Check whether you have a spare tire and whether it is inflated. A lot of people only remember it when they need it, and by then it has been sitting flat for years because nobody ever checked.
Our Advice
Bring it in for a summer checkup and we will cover everything in one visit: AC, cooling, tires, brakes, battery. One afternoon at the shop saves a lot of headaches on the road. Book early, shops get packed before the season.
