Hello, Lykkers! If you are planning to leave your car unused for weeks or months, a bit of preparation can save you from costly repairs.
Many drivers park their vehicles and forget them, only to return to a dead battery, flat tires, or worse. Here is a straightforward guide to keeping your car in good shape while it sits idle.

Preparing the Vehicle Interior and Exterior

Start by giving the car a thorough wash and wax to protect the paint from dust and moisture. Clean the interior as well, removing any food wrappers or crumbs that could attract pests. Consider using a car cover made of breathable fabric to prevent scratches and UV damage. If you park outdoors, a waterproof cover is essential, but make sure it allows air circulation to avoid trapping moisture.

Fuel and Fluid Management

Fill the fuel tank to near full to prevent condensation from forming inside the tank. Add a fuel stabilizer according to the product instructions, then run the engine for about ten minutes to let the stabilized fuel circulate. Change the engine oil and filter before storage, because old oil contains acids that can damage engine components over time. Top off all other fluids, including coolant and brake fluid, to prevent corrosion.

Battery and Electrical Care

A battery will slowly discharge even when the car is off. The best solution is to connect a trickle charger or battery maintainer. If you don't have one, disconnect the negative battery cable to slow the drain. Just remember that disconnecting the battery will reset your radio presets and clock.

Tire and Suspension Protection

Inflate the tires to the maximum pressure recommended in the owner's manual, usually around 40 to 50 psi. This prevents flat spots from forming where the rubber meets the ground. If possible, park the car on jack stands to take the weight off the tires completely. If you leave the car on the ground, move it forward or backward a few feet every two weeks to shift the contact patch.

Moisture, Pests, and Ventilation

Place moisture absorbers or silica gel packs inside the cabin to reduce humidity. Close all windows and vents, but leave the interior air circulation on recirculation mode if the car has it. To keep rodents out, stuff steel wool into the exhaust pipe and any gaps where they might enter. Mothballs or peppermint oil can also deter pests, but place them in a container to avoid staining the carpets.

Starting and Moving the Car

If the car will be stored for more than a month, try to start it every two to three weeks. Run the engine until it reaches operating temperature, about 15 minutes, and engage the air conditioner for a few minutes to keep the seals lubricated. Drive the car around the block to work the brakes and transmission, if possible. This prevents rust from forming on brake rotors and keeps the gearbox lubricated.

Insurance and Paperwork

Check with your insurance provider about coverage during storage. Some policies offer reduced rates when the car is not driven. Also, make a note to renew registration and inspection before you plan to drive it again. Keep the key in a safe place and consider using a steering wheel lock for security.
Taking a little time to prepare your car for long term storage will pay off when you are ready to drive it again. Follow these steps, and your vehicle will be just as reliable as the day you parked it. Got any tricks of your own? Share them with us and keep your ride in top shape.
