Just like humans, cars don't like extreme heat or extreme cold. Since summer is upon us, let's talk about the maintenance you can be doing to avoid a costly breakdown.

Cooling system: One of the most common primary cause of summer breakdowns is overheating caused by a cooling system malfunction. A cooling system that isn't running at peak efficiency cannot keep the engine at the correct operating temperature. Get it flushed every 30,000 miles to ensure everything is moving smoothly.

A note for do-it-yourselfers: The most common coolant type contains ethylene glycol, which according to the EPA is toxic to humans and animals. Because of this it must be disposed of properly, so a flush might be something you should let a professional perform for you. When performing a coolant flush, the technician should also check the condition of the belts, hoses, engine fan, and thermostat. Any of these could cause a problem, so they should be inspected by a trained professional.

Oil: We all know that oil is the lifeblood of your engine, and it also provides cooling for your engine so don't overlook this important element. Replacing the oil at the OEM (original equipment manufacturer) suggested intervals is essential. It is just as important to use the oil weight and grade specified by your OEM (check your owner's manual for the requirements).

Air conditioning: Your car's A/C keeps you cool, but if it's not clean it can cause engine overheating. The A/C condenser is located right in front of the radiator and a dirty condenser can block airflow to it. As a result of emission requirements, newer engines have higher operating temperatures than engines built, say, 20 years ago. Because of this, their cooling systems must be operating at peak performance to provide the durability we have come to expect.

Overall, maintenance is the keyword to remember here. By doing a little upkeep now, your car should be running happily into the fall.

Nuts & Bolts


Get the whole family involved.

Spring is here, so that means it's time to think about doing some spring cleaning on your vehicle. In between the vacuuming and window polishing, you may forget about one very important step: Your paint job needs a good coat of wax every six months to protect the paint and the clear coat.

You see, when they paint your vehicle, the last coat they put on is called the clear coat. It's paint without a pigment, and it's what gives your paint job that multi-dimensional look while also protecting it.

So unless you want to end up having your clear coat turn chalky and look terrible — and we've all seen that — you need to protect it with a good wax job.

To do it right, you want to wax your car by hand and use the best wax you can find. Take advantage of having everyone at home right now and make it a family event.

Just remember, if you don't see the water bead up on the paint, it's time to wax.

Now's the time to buy.

On his show "Let's Talk Wheels," Mike Herzing answers questions from listeners who write in. While their specific situation might not match yours exactly, there's still plenty to be learned from their experiences — and his expertise.

Daphne writes: I heard you mention last week that new car deals are terrific right now. I am in the market for a new compact hatchback or SUV for commuting 60 miles a day in traffic. Since you always say there are no bad cars on the market these days, what would you choose if you had a budget of $20,000?

Mike Herzing: Indeed, new car deals with zero percent financing, rebates, and even deferred payments have been announced by several dealerships. My first pick would be the Hyundai Kona (priced from $20,300) followed by the Jeep Renegade, (priced from $22,375) and the Mazda CX30 (priced from $21,300).

My next choices would be the Nissan Kicks (from $18,870) and, finally, the Hyundai Venue (from $17,350). These prices are list prices. It's important to remember that dealerships are in the business of making deals. Also, to curb the spread of COVID-19, many dealers are selling cars without physical contact with the customer. This service includes delivering your new vehicle free of charge.

Les writes: I just bought a 2020 Wrangler and love it! But when should I change the oil? I have heard people saying 3,000 miles and also those saying 7,000. I live in Dacula, Georgia, outside of Atlanta and my mileage is mostly highway and some off-roading.

MH: If it were mine, I would change the oil at 5,000 miles and use at least a synthetic blend oil. Using a full synthetic would be even better. You'll also want to take that opportunity to rotate the tires at the same time.

The 2020 Jeep Wrangler owner's manual says to change your oil every 3,500-4,000 miles and no less than once every 12 months. The change oil message will illuminate when it's been 3,500 miles since your last oil change.
