Winter can be a tough time for classic cars, but proper storage ensures your beloved vehicle stays in top shape.
Whether you’re a seasoned collector or a first-time owner, preparing for the winter months requires careful attention to detail. Drawing from Hagerty and other trusted classic car preservation resources, here’s a breakdown of essential tips and tricks for protecting your classic car until Spring.
1. Find the Ideal Storage Location
Your classic car deserves more than just a space in the driveway or backyard. For optimal protection, store it in a dry, temperature-controlled garage. Extreme fluctuations in temperature can cause metal parts to expand and contract, leading to cracks and rust. If a climate-controlled garage isn’t available, a high-quality car cover designed for outdoor use can be a good alternative, but avoid using cheap, non-breathable covers.
Tip
Use a moisture absorber in enclosed spaces to avoid mildew buildup, especially in garages prone to humidity.
2. Start with a Full Detailing Session
Before storing, give your car a thorough wash and wax. Even a thin layer of dirt or road salt can cause corrosion over time. Pay special attention to the undercarriage, where rust can start unnoticed. A coat of wax provides a barrier between your car’s paint and the harsh elements.
Tip
Apply rubber protectant to weather stripping around doors and windows to prevent them from cracking during cold weather.
3. Prevent Tire Damage
Long-term storage can lead to flat spots on your tires, which happens when the car’s weight compresses the same area for months. You can prevent this by inflating your tires to the maximum recommended PSI or using jack stands to relieve the tires of weight altogether.
Tip
For additional peace of mind, consider moving the car slightly every few weeks to rotate the tires, even if it’s just back and forth in the garage.
4. Battery Maintenance is Key
Winter can be brutal on car batteries. To avoid finding a dead battery in spring, disconnect it or use a battery tender. A tender will keep the battery charged without overloading it, ensuring it’s ready to go once you’re back on the road.
Tip
Store the battery in a cool, dry place, ideally off the concrete floor, as cold can diminish its charge. Some owners even recommend placing it on a wooden board for insulation.
5. Add Fuel Stabilizer
Leaving fuel in the tank for months can cause it to degrade, leading to clogs and poor engine performance. A fuel stabilizer helps prevent the fuel from breaking down. Make sure to fill the tank after adding the stabilizer, as a full tank reduces the chance of moisture accumulating.
Tip
Run the engine for a few minutes after adding the stabilizer to ensure it circulates through the system.
6. Rodent-Proof Your Vehicle
Rodents love using warm cars as shelter during winter, and they can chew through wires or build nests in your engine. To prevent unwanted guests try these tips.
Tips
- Block entry points like exhaust pipes or air intakes with steel wool or mesh.
- Place dryer sheets in and around the car—many owners report that these strong smells deter rodents.
- For extra security, try Irish Spring soap or peppermint oil, as their scents are known to repel rodents without leaving unpleasant residue inside the car.
7. Cover and Protect
Whether in a garage or outside, covering your classic car is vital. For indoor storage, a soft, breathable cover prevents dust accumulation without trapping moisture. For outdoor storage, ensure the cover is waterproof but breathable to prevent mold and mildew.
Tip
Leave the windows slightly cracked to allow ventilation, preventing condensation buildup that could lead to mildew inside the car.
8. Check Fluids and Top Off
Before storing, check all the car’s fluids—oil, coolant, and brake fluid. Top off anything that’s low, and consider changing the oil to avoid contaminants sitting in the engine over winter. Fresh oil reduces the chance of corrosion on engine components.
Tip
Some owners go the extra mile and add antifreeze to the cooling system, even if the car won’t be driven, just to ensure it stays protected during storage.
Why a Classic Car Insurance Policy is Essential for Winter Storage
While these steps go a long way in protecting your car physically, don’t forget the importance of the right insurance policy during the off-season. Standard auto insurance policies may not cover the full value of a classic vehicle, and here’s why a classic car insurance policy is a much better option for winter storage:
1. Agreed Value Coverage: Unlike standard policies, classic car insurance provides agreed value coverage, meaning you and the insurer agree on the value of your car upfront. In case of a total loss, you get paid the agreed amount, not the depreciated market value.
2. Comprehensive Coverage: Classic car policies often offer more comprehensive protection while the vehicle is in storage. This includes coverage for theft, vandalism, or damage from weather-related incidents while the car isn’t being driven.
3. Lower Premiums for Limited Use: Since classic cars are typically driven less, many classic car policies offer lower premiums compared to regular auto insurance. You’re not paying for the risks associated with daily driving, which can make insuring your classic during winter much more cost-effective.
4. Specialized Claims Handling: Insurance Zehr Insurance understand the unique needs of classic car owners. We offer access to appraisers and mechanics familiar with rare and vintage vehicles, ensuring that your car is properly cared for in case of damage.
Final Thoughts
Proper winter storage is more than just parking your classic car and covering it up. With careful attention to detail, from cleaning and covering to rodent-proofing and battery maintenance, you can ensure your vehicle comes out of storage looking as good as it did when you parked it.
And don’t forget, a classic car insurance policy provides an added layer of security, ensuring your car is financially protected all year round.
Take the time to follow these expert-recommended steps, and you’ll be well ahead of the curve when it’s time to cruise again. Whether you’re in a cold or mild climate, the key is consistent maintenance, even during downtime.
