We believe that proactive maintenance is the key to a worry-free summer on the road.

1. The Lifeline of Your Engine: Checking Your Coolant System

Your engine's cooling system is its first line of defense against overheating, especially during the hot summer months in Ann Arbor. Ensuring it's functioning correctly is paramount.

• Coolant Level Inspection: Regularly check your coolant level in the reservoir. It should be between the "full" and "low" marks. If it's consistently low, it could indicate a leak in the system.
• Coolant Concentration: Coolant isn't just water; it's a mixture of antifreeze and water. The correct ratio is essential for both preventing freezing in winter and overheating in summer. You can purchase a coolant tester to check the concentration, or better yet, bring it to K & N Automotive in Ann Arbor, and we'll ensure it's properly balanced.
• Coolant Flush: Over time, coolant can become contaminated with rust and debris, reducing its effectiveness. We recommend a coolant flush every two to three years, or as recommended by your vehicle's manufacturer. At K & N Automotive in Ann Arbor, we perform thorough coolant flushes to keep your cooling system in optimal condition.
• Hose Inspection: Examine the hoses connected to your radiator and engine for any signs of leaks, cracks, swelling, or softness. These hoses carry coolant, and a failure can lead to rapid coolant loss and overheating. Our technicians at K & N Automotive in Ann Arbor, MI, can inspect and replace worn hoses as needed.
• Radiator Cap Check: The radiator cap plays a vital role in maintaining pressure within the cooling system. Inspect it for any damage or corrosion. A faulty cap can lead to coolant leaks and reduced cooling efficiency.

2. The Lifeblood of Your Engine: The Importance of Timely Oil Changes

Engine oil lubricates the moving parts of your engine, reducing friction and dissipating heat. High summer temperatures in Ann Arbor can cause your engine oil to break down more quickly, making regular oil changes even more critical.

• Oil Level and Condition: Check your engine oil level regularly using the dipstick. The level should be between the "full" and "add" marks. Also, pay attention to the color and consistency of the oil. It should be a light to medium brown color and relatively clear. Dark, sludgy oil indicates it's time for a change.
• Oil Change Intervals: Follow your vehicle manufacturer's recommended oil change intervals. However, if you do a lot of stop-and-go driving in Ann Arbor traffic or frequently drive in very hot conditions, you might consider more frequent oil changes.
• Choosing the Right Oil: Using the correct type and viscosity of oil for your vehicle is essential, especially in summer. Our experts at K & N Automotive in Ann Arbor, can recommend the best oil for your car and driving conditions. We offer a range of oil change services to meet your needs.

3. The Supporting Cast: Inspecting Belts and Hoses

Your engine relies on a system of belts and hoses to power various components, including the alternator, water pump, and air conditioning compressor. Summer heat can cause these components to weaken and crack.

• Belt Inspection: Examine all visible belts for signs of wear, such as cracks, fraying, missing chunks, or excessive stretching. A broken belt can leave you stranded on the side of the road in the Ann Arbor heat.
• Hose Inspection: As mentioned earlier, check all hoses for leaks, cracks, swelling, or softness. Pay particular attention to hoses carrying coolant and refrigerant.
• Proactive Replacement: It's often wise to replace belts and hoses proactively before they fail, especially if they are showing signs of wear. Our technicians at K & N Automotive in Ann Arbor, MI, can inspect your belts and hoses and advise on when replacement is necessary.

4. Powering Through the Heat: Checking Your Battery

While cold weather is often blamed for battery failures, extreme heat can also take a toll on your car battery. High temperatures can cause the fluid inside the battery to evaporate, potentially leading to reduced performance and premature failure.

• Visual Inspection: Check your battery terminals for corrosion, which appears as a white or bluish powdery substance. Clean any corrosion with a wire brush and a mixture of baking soda and water. Ensure the battery cables are securely fastened.
• Battery Load Test: A battery load test can determine the overall health and remaining capacity of your battery. We can perform this test for you at K & N Automotive in Ann Arbor, to ensure your battery is ready for the demands of summer driving.
• Battery Age: Keep track of the age of your battery. Most car batteries have a lifespan of around three to five years. If your battery is approaching this age, it might be a good idea to have it tested, especially before the peak summer heat hits Ann Arbor.

5. Staying Cool Inside: Servicing Your Air Conditioning System

While not directly related to engine function, a properly working air conditioning system is essential for your comfort during the Ann Arbor summer. A struggling AC system can also put extra strain on your engine.

• Check AC Performance: Turn on your air conditioning and make sure it's blowing cold air. If it's weak or not cooling at all, it could indicate a refrigerant leak or another issue.
• Refrigerant Recharge: Over time, your AC system may lose refrigerant, which is necessary for cooling. Our technicians at K & N Automotive in Ann Arbor, can check your refrigerant levels and recharge the system if needed.
• Cabin Air Filter Replacement: The cabin air filter helps to keep dust, pollen, and other pollutants out of your vehicle's interior. A clogged filter can reduce airflow and AC efficiency. We recommend replacing the cabin air filter regularly, and summer is a great time to do it.

6. Keeping an Eye on the Thermometer: Monitoring Your Engine Temperature

Your vehicle's temperature gauge is your direct indication of how hot your engine is running. Pay attention to it, especially during hot weather and heavy traffic in Ann Arbor.

• Normal Operating Temperature: Familiarize yourself with your vehicle's normal operating temperature range. This is usually around the middle of the gauge.
• Overheating Warning: If the temperature gauge starts to climb towards the "hot" mark, it's a sign that your engine is overheating. Pull over to a safe location as soon as possible and turn off the engine to allow it to cool down. Do not attempt to remove the radiator cap while the engine is hot, as this can cause severe burns.
• Seek Professional Help: If your engine overheats, don't attempt to drive it further. Contact K & N Automotive in Ann Arbor, and we can provide towing and expert diagnosis and repair.

7. Breathing Easy: Checking Your Engine Air Filter

The engine air filter prevents dust, dirt, and other debris from entering your engine. A clogged air filter restricts airflow, which can reduce engine performance and fuel efficiency, especially in hot weather when the engine needs to work harder.

• Visual Inspection: You can often visually inspect your engine air filter. If it looks dirty or clogged, it's time for a replacement.
• Replacement Intervals: Follow your vehicle manufacturer's recommended air filter replacement intervals. If you drive in dusty conditions frequently in or around Ann Arbor, you might need to replace it more often. Our team at K & N Automotive can quickly and easily replace your engine air filter.

8. The Right Pressure: Maintaining Proper Tire Inflation

While not directly an engine component, proper tire inflation is crucial for overall vehicle performance and safety, especially in the summer heat. Underinflated tires can overheat and even blow out.

• Check Tire Pressure Regularly: Check your tire pressure at least once a month and before any long trips, especially during the summer months in Ann Arbor. Inflate your tires to the pressure recommended on the sticker located on your driver's side doorjamb or in your owner's manual.

9. Lighten the Load: Avoiding Overloading Your Vehicle

Overloading your vehicle puts extra strain on the engine, transmission, brakes, and tires, especially in hot weather. Be mindful of your vehicle's weight capacity and avoid carrying excessive loads.

10. Seek the Shade: Parking Smart in the Summer Sun

Whenever possible, try to park your vehicle in the shade. This will help to keep the interior cooler and reduce the heat buildup under the hood, lessening the stress on your engine components.

11. The Foundation of Reliability: Regular Maintenance Checks at K & N Automotive
