Beat the Heat: Essential Summer Maintenance for Your RV, Car, and SUV in Central PA
Summer in Central Pennsylvania is a time for road trips, camping, and outdoor adventures. But rising temperatures can take a toll on your vehicle—whether it’s an RV, car, or SUV. Without proper maintenance, the summer heat can lead to breakdowns, reduced performance, and costly repairs. This guide covers essential summer maintenance tips to keep your vehicle running smoothly and safely all season long.
1. Keep Your Engine Cool
Your engine works harder in the heat, making the cooling system one of the most critical components during summer. Check your coolant level and top it off with a 50/50 mix of antifreeze and water. Inspect the radiator and hoses for leaks, cracks, or bulges. If your vehicle hasn’t had a coolant flush in the past two years, now’s the time.
Tip: If you’re towing a trailer or driving an RV through the mountains of Central PA, your engine will heat up faster—so don’t skip this step.
2. Maintain Proper Tire Pressure
Tire pressure fluctuates with temperature changes. Underinflated tires can overheat and blow out, while overinflated tires reduce traction. Check your tire pressure at least once a month and before long trips. Don’t forget to inspect the spare tire and look for signs of uneven wear or dry rot.
Pro Tip: For RVs and trailers, use a tire pressure monitoring system (TPMS) to keep tabs on pressure in real time.
3. Test the Air Conditioning System
There’s nothing worse than a broken A/C on a 90-degree day. Run your air conditioning system and check for weak airflow, strange smells, or unusual noises. If it’s not cooling properly, it could be due to low refrigerant, a clogged cabin filter, or a failing compressor.
DIY Check: Replace the cabin air filter—it’s a quick and inexpensive fix that can dramatically improve airflow.
4. Check and Top Off Fluids
Summer heat accelerates fluid breakdown. Check and top off all essential fluids, including:
- Engine oil
- Transmission fluid
- Brake fluid
- Power steering fluid
- Windshield washer fluid
If any fluid looks dirty or smells burnt, it’s time for a change. For RVs, don’t forget to check generator oil and hydraulic fluids if applicable.
5. Inspect Belts and Hoses
Rubber components degrade faster in high temperatures. Inspect belts for fraying, glazing, or cracking. Check hoses for bulges, leaks, or soft spots. A failed belt or hose can leave you stranded on the side of Route 322 or I-81—not ideal on a hot summer day.
6. Clean and Protect the Exterior
Sun and heat can damage your vehicle’s paint and trim. Wash your vehicle regularly to remove dirt and road grime, then apply a UV-protectant wax. For RVs, pay special attention to the roof and awnings, which are especially vulnerable to sun damage.
Bonus: Use tire protectant to prevent cracking and fading from UV exposure.
7. Prepare an Emergency Kit
Even with the best maintenance, breakdowns can happen. Prepare a summer emergency kit that includes:
- Water and snacks
- Sunscreen and hats
- Jumper cables
- Tire repair kit and inflator
- Flashlight and batteries
- First aid kit
For RVs, include extra coolant, oil, and fuses. If you’re traveling through rural areas of Central PA, cell service may be spotty—so plan accordingly.
Conclusion
Summer is the perfect time to explore the beauty of Central Pennsylvania, from the Appalachian Trail to Raystown Lake. But before you hit the road, make sure your vehicle is ready for the heat. With these summer maintenance tips, you’ll reduce the risk of breakdowns, improve performance, and enjoy a safer, more comfortable ride—whether you're in a compact SUV or a 40-foot motorhome.
