6 Easy Ways to Prepare Your Vehicle for Spring

1. Clean your car to remove salt and calcium

Removing debris can help preserve your paint job

Keeping your vehicle clean can help preserve the paint job—and can even help prevent rust damage to the body itself. Road salt left on a vehicle often results in corrosion, and can eat away at your paint and undercarriage. Likewise, bug debris and other crud left on your paintjob can degrade the clear coat (especially in direct sunlight or rising temperatures). A thorough handwash is ideal, paying particular attention to the underside of the vehicle and wheel wells (automated carwashes don’t always have mechanisms to clean the underside of your vehicle). A little TLC now can go a long way in helping keep your car in good condition all year.

2. Check your windshield wipers and washer fluid

Make sure your wipers are working and the fluid reservoir is full. Spring and summer rains often arrive unexpectedly, and you’ll want to make sure your wipers are in good condition before you get caught in a surprise storm.

3. Check your air conditioning system

Check to see if your A/C unit is working before summer temperatures arrive. If a repair is necessary, you’ll have a bit more time to prepare before the weather really heats up.

4. Check your tires

Examine your tires to make sure you have the manufacturer’s recommended amount of tread remaining. For a quick, at-home check, take a penny (with “heads” facing you) and insert Lincoln’s head into the tread groove. If you can see all of his head, you most likely need to replace your tires. (This is also a good time to check for uneven tire wear). When in doubt, visit your trusted mechanic.

5. Check your battery

Dying batteries often show symptoms before they give up the ghost. For a quick at-home check, turn on your headlights (without starting the engine) and leave them on for a few minutes. Start the car, and pay attention to the brightness of the lights—if they dim or flicker, your battery may need to be replaced. Keep in mind that your local auto parts store is likely able to check your battery’s charge (often for free).

6. Check your engine air filter

Inspect your K&N® High-Flow Air Filter™, and be sure to clean it when the dirt exceeds the wire mesh. Since K&N filters are washable and reusable, you can easily clean and re-oil your filter using K&N Recharger® kits—find yours here!
