Summer brings sunny skies and road trip opportunities, but it also puts extra strain on your car, especially if it’s an older vehicle. High temperatures can reveal hidden weaknesses and accelerate wear on aging components. Keeping your older car running reliably during the hottest months requires some proactive care. Here are the essential summer maintenance tips to help your vehicle handle the heat and keep you safely on the road.
Check and Maintain the Cooling System
The cooling system is one of the most critical areas to inspect before summer hits. Older vehicles are more prone to leaks and component failures, which can quickly lead to overheating.
Inspect the radiator for signs of corrosion or damage, and make sure the hoses are free of cracks and feel firm to the touch. Check your coolant level and quality. Coolant that looks rusty or dirty should be flushed and replaced.
The thermostat and water pump should also be checked if they haven’t been serviced recently. Any issues here can leave you stranded on a hot roadside.
Inspect Belts and Hoses
Heat accelerates the wear of rubber components like belts and hoses. Over time, these parts can become brittle, crack, or lose tension.
Older vehicles, in particular, may have original or long-ignored belts that could fail without warning. Have a professional inspect them and replace any that show signs of aging or excessive wear.
Test the Battery
High temperatures can be tough on batteries, causing fluid inside to evaporate and leading to internal damage.
For older vehicles, a weak or aging battery is more likely to fail when pushed to its limits in the summer heat. Have the battery tested to ensure it holds a proper charge and inspect the terminals for corrosion or loose connections.
Check Tire Condition and Pressure
As temperatures rise, so does tire pressure. For older vehicles, tires may already have weakened sidewalls or uneven wear, which can be exacerbated in hot weather.
Check the tread depth and look for cracks or bulges. Make sure tire pressure is set to the manufacturer’s recommendations to ensure optimal grip and safety.
Evaluate the Air Conditioning System
Driving an older car without functioning air conditioning can turn a summer drive into an uncomfortable ordeal.
Test your A/C system before the hottest days arrive. If it’s not cooling properly, it may need a refrigerant recharge, or there could be leaks or failing components like the compressor. Prompt attention ensures you stay cool and avoid more expensive repairs later.
Replace Old Fluids
Fluids deteriorate over time, and older cars typically require fewer changes. Summer is a good time to replace engine oil, brake fluid, and transmission fluid if they’re overdue.
Fresh fluids improve system performance and help components operate more efficiently, reducing the risk of overheating or failure under stress.
Inspect Wipers and Lights
While summer usually means less rain, sudden downpours can still occur. Older wiper blades may have hardened or cracked, affecting visibility during storms.
Check that all exterior lights, including brake and turn signals, are functioning properly. Ensuring visibility is especially important when traveling on busy highways during summer vacations.
Schedule a Comprehensive Inspection
Older vehicles benefit greatly from a professional multi-point inspection before the summer season. A thorough check can uncover hidden problems with brakes, suspension components, or other critical systems.
Addressing these issues early helps prevent breakdowns when you’re miles away from home or in extreme temperatures.
