Storing a car for an extended period requires careful planning and attention to detail. Whether you’re storing a classic car, a seasonal vehicle, or simply a car that won’t be in use for a while, taking the right steps to protect it can prevent damage and ensure it’s in good condition when you’re ready to drive it again. From preparing the engine to choosing the right storage environment, here’s how to take care of a car in long-term storage.
Preparing the Engine and Fluids
Before placing your car in long-term storage, it’s essential to prepare the engine and fluids to prevent any potential damage. The fluids in your car can degrade over time, leading to corrosion, blockages, and other mechanical issues. Properly maintaining these fluids will help preserve the engine’s integrity while the car is in storage.
Key Steps for Engine and Fluid Maintenance
- Oil Change: Change the oil and oil filter before storing your car. Old oil can contain contaminants that may cause corrosion over time. Fresh oil will help protect the engine’s internal components during storage.
- Coolant Check: Ensure the coolant is topped up and that it has the correct mix of antifreeze and water. This will prevent the coolant system from freezing in cold weather and protect the engine from overheating if the storage area gets warm.
- Fuel Stabilizer: Add a fuel stabilizer to the gas tank to prevent the fuel from breaking down and causing blockages in the fuel system. After adding the stabilizer, run the engine for a few minutes to circulate it throughout the system.
- Battery Maintenance: Either disconnect the battery or use a battery maintainer (trickle charger) to keep the battery charged during storage. This prevents the battery from draining and becoming unusable.
AAA recommends changing the oil and adding a fuel stabilizer before long-term storage to prevent engine damage and ensure the car starts smoothly when you’re ready to use it again.
Choosing the Right Storage Environment
The environment in which you store your car plays a significant role in its preservation. Choosing the right storage space can protect your car from environmental factors such as temperature fluctuations, humidity, and pests.
Factors to Consider for Storage Environment
- Indoor vs. Outdoor Storage: If possible, store your car indoors in a garage or storage facility. Indoor storage offers better protection from the elements, reducing the risk of rust, paint damage, and other weather-related issues.
- Climate Control: If you’re storing a valuable or classic car, consider a climate-controlled storage unit. This type of storage regulates temperature and humidity levels, preventing moisture buildup and the subsequent risk of rust and mold.
- Ventilation: Ensure the storage area is well-ventilated to prevent condensation from forming on the car, which can lead to rust. Proper ventilation also helps to reduce the buildup of fumes and odors.
- Pest Prevention: Take steps to protect your car from pests, such as rodents, which can cause significant damage. Use mothballs, rodent repellent, or traps to keep pests away from your vehicle.
Table: Comparing Indoor and Outdoor Storage
| Storage Option | Protection Level | Ideal For |
| Indoor Storage | High protection from weather and environmental factors | Classic cars, high-value vehicles, long-term storage |
| Climate-Controlled Storage | Superior protection with regulated temperature and humidity | Valuable, sensitive vehicles |
| Outdoor Storage | Basic protection, but exposed to elements | Short-term storage, less valuable vehicles |
| Covered Outdoor Storage | Moderate protection with cover or carport | Cost-effective, seasonal vehicles |
The U.S. Department of Energy suggests that storing a car in a climate-controlled environment can extend the life of the vehicle by preventing moisture-related damage and deterioration.
Using Car Covers for Added Protection
Even if your car is stored indoors, using a car cover can provide an extra layer of protection. A high-quality car cover shields your vehicle from dust, dirt, and minor dings, ensuring it remains in pristine condition throughout the storage period.
Benefits of Using a Car Cover
- Dust and Dirt Protection: Over time, dust and dirt can accumulate on your car, potentially scratching the paint or dulling the finish. A car cover keeps your vehicle clean and free from contaminants.
- Scratch Prevention: Car covers can protect your vehicle from minor scratches and dings that might occur in a storage facility or garage. This is especially important if other items are stored near the car.
- UV Protection: If your car is stored in an area with windows or partial sunlight, a car cover can provide UV protection, preventing the paint and interior from fading.
- Moisture Control: Some car covers are designed to be breathable, allowing moisture to escape while keeping water out. This prevents condensation from forming under the cover, which can lead to rust and mold.
When choosing a car cover, it’s important to select one that fits your vehicle properly and is made from materials suitable for long-term storage. Opt for a cover with multiple layers and a soft inner lining to provide maximum protection.
Car and Driver magazine emphasizes the importance of using a car cover during long-term storage, noting that it can prevent up to 80% of the damage caused by environmental factors such as dust, moisture, and UV rays.
Regular Maintenance Checks
Even though your car is in storage, it’s important to perform regular maintenance checks to ensure everything remains in good condition. Periodic inspections can help you catch potential issues early and prevent long-term damage.
Suggested Maintenance Activities
- Tire Pressure: Check the tire pressure every few months to ensure they remain properly inflated. Tires can lose air over time, and underinflated tires can develop flat spots, which can be costly to repair.
- Fluid Levels: Regularly check the fluid levels, including oil, coolant, and brake fluid, to ensure they haven’t leaked or degraded. Top them up as necessary to keep the engine and other systems in good working order.
- Battery Charge: If you’ve disconnected the battery, consider reconnecting it every few months to start the car and let it run for a few minutes. This keeps the engine components lubricated and prevents the battery from losing its charge entirely.
- Pest Inspection: Inspect the car for any signs of pests or rodents. Look for nests, chewed wires, or droppings, and take action if you notice any issues.
The National Highway Traffic Safety Administration (NHTSA) recommends regular maintenance checks for stored vehicles to prevent damage and ensure the car is ready to drive when needed.
Conclusion
Taking care of a car in long-term storage requires careful planning and attention to detail. By preparing the engine and fluids, choosing the right storage environment, using a car cover, and performing regular maintenance checks, you can protect your vehicle from damage and ensure it remains in excellent condition. Whether you’re storing a classic car, a seasonal vehicle, or simply putting your car away for an extended period, following these steps will give you peace of mind and help maintain the value and performance of your vehicle.
