So, you're thinking about tucking your trusty steed away for the winter? Maybe you're a snowbird heading south, or perhaps you just prefer a different vehicle when the snow starts to fly. Whatever the reason, properly winterizing your car for storage is crucial to ensure it emerges in spring ready to roll, not riddled with issues. Think of it as sending your car into hibernation, but with a bit more care and preparation involved than just leaving it in the garage!
How to Prepare Your Car for Winter Storage
Preparing your car for winter storage is a proactive process that protects it from the harsh effects of disuse and the elements. Neglecting this process can lead to a range of problems, from a dead battery to rusted components and even rodent infestations. The steps below outline a comprehensive approach to ensuring your vehicle survives the winter months unscathed.
Cleaning and Detailing
Before you even think about fluids or covers, a thorough clean is paramount. Think of it this way: you wouldn't go to sleep in dirty clothes, would you? The same applies to your car. Dirt, grime, and salt (if it's been driven in winter conditions) can all contribute to corrosion and damage over time. A clean car is a happy car, especially when it's going into storage.
Exterior Wash and Wax
Start with a complete exterior wash, paying special attention to the undercarriage. This area is prone to accumulating salt and road debris, which can accelerate rust formation. Use a pressure washer if possible, but be careful not to damage the paint. Once the car is clean, apply a coat of high-quality wax. Wax acts as a protective barrier against moisture and UV rays, both of which can harm the paint during storage. Consider a ceramic coating for even longer-lasting protection.
Interior Detailing
The interior needs attention, too. Remove all trash, personal belongings, and anything that might attract pests. Vacuum the carpets and upholstery thoroughly. Clean all surfaces with appropriate cleaning products. Leather seats should be conditioned to prevent them from drying out and cracking. Leaving food crumbs or other organic matter inside is an open invitation for rodents, so be meticulous. Remember to check the glove compartment, center console, and under the seats.
Fluid Management: A Car's Lifeblood
Fluids are essential to your car's health, and addressing them before storage is crucial. Old fluids can degrade and cause damage over time. Let's break down each fluid individually.
Oil Change
This is perhaps the most important step. Old engine oil contains contaminants and acids that can corrode internal engine parts while the car sits idle. A fresh oil change with a new filter will protect the engine during storage. Always use the manufacturer's recommended oil type and viscosity. Consider a high-quality synthetic oil for added protection. Changing the oil before storage is like giving your engine a protective blanket for the winter.
Fuel Stabilization
Gasoline can degrade and form gum and varnish deposits when stored for extended periods. These deposits can clog fuel injectors and fuel lines, leading to starting problems and poor performance when you eventually bring the car out of storage. Adding a fuel stabilizer to the gas tank will prevent this degradation. Follow the instructions on the fuel stabilizer bottle carefully, and make sure to run the engine for a few minutes after adding the stabilizer to ensure it circulates throughout the fuel system. A good rule of thumb is to fill the gas tank nearly full to minimize condensation inside the tank which can lead to rust.
Coolant Check
Check the coolant level and condition. If the coolant is old or contaminated, flush and replace it with a fresh mixture of coolant and distilled water (usually a 50/50 mix). Coolant protects the engine from freezing in cold temperatures and prevents corrosion. Use a coolant tester to check the freeze protection level. Ensure the coolant mixture is adequate for the lowest temperatures expected during the storage period.
Brake Fluid Inspection
Brake fluid is hygroscopic, meaning it absorbs moisture from the air. This moisture can lead to corrosion in the brake system and reduce braking performance. Test the brake fluid for moisture content using a brake fluid tester. If the moisture content is high (typically above 3%), have the brake fluid flushed and replaced. A properly functioning brake system is crucial for safety, so don't neglect this step.
Battery Care: Keeping the Power On (or Off)
Batteries are notorious for dying when left unused for long periods. Cold weather can further exacerbate this problem. There are a few options for preserving battery life during storage.
Battery Disconnect
The simplest option is to disconnect the battery. This prevents any parasitic drain from the car's electrical system. Disconnect the negative terminal first, followed by the positive terminal. Be sure to clean the battery terminals with a wire brush before reconnecting the battery in the spring. Keep in mind that disconnecting the battery may reset the car's computer, so you may need to re-enter radio codes or other settings when you reconnect it.
Battery Tender
A battery tender, also known as a trickle charger, is a device that slowly charges the battery to maintain its charge level. This is a good option if you want to keep the battery in good condition without having to disconnect it. Connect the battery tender to the battery terminals and plug it into an outlet. The battery tender will automatically monitor the battery's charge level and provide a small amount of current to keep it fully charged. This prevents sulfation, which is a common cause of battery failure. Asmart charger is even better as it will shut off automatically when the battery is full, preventing overcharging.
Tire Pressure and Protection
Tires can lose pressure over time, and sitting in one position for months can cause flat spots. Proper tire inflation and protection can prevent these issues.
Inflate Tires
Inflate the tires to the maximum pressure recommended on the tire sidewall. This will help prevent flat spots from forming. Check the tire pressure regularly during storage and re-inflate as needed. Consider using tire cradles, which are designed to distribute the weight of the car evenly across the tires and prevent flat spots. If you don't have tire cradles, you can move the car slightly every month to shift the weight and prevent flat spots from forming.
Protect From Sunlight
Covering the tires with tire covers will protect them from UV rays, which can cause the rubber to dry out and crack. This is especially important if the car is stored outdoors. You can find tire covers at most auto parts stores. They are a relatively inexpensive way to protect your tires and extend their lifespan.
Protecting Against Pests and the Elements
Rodents and the elements can cause significant damage to a stored car. Taking preventative measures can save you a lot of headaches in the spring.
Rodent Prevention
Rodents love to nest in cars, especially during the winter months. They can chew through wiring, upholstery, and other components, causing extensive damage. To prevent rodent infestations, take the following steps:
- Seal any openings in the car's body, such as gaps around the doors and windows.
- Place mothballs or rodent repellent pouches inside the car.
- Set up rodent traps around the car.
- Consider using electronic rodent repellents that emit ultrasonic sound waves.
- Never store food or trash near the car.
Car Cover
A car cover is essential for protecting the car from the elements, especially if it's stored outdoors. Choose a high-quality car cover that is breathable and waterproof. Breathable covers allow moisture to escape, preventing condensation from forming under the cover, which can lead to rust. Waterproof covers protect the car from rain and snow. Make sure the cover fits snugly to prevent it from blowing off in the wind. Consider investing in an indoor car cover if you are storing the car inside to protect it from dust and accidental scratches.
Final Checklist Before Storage
Before you button everything up and walk away, take a moment to review this final checklist:
- Remove the windshield wipers to prevent them from sticking to the windshield.
- Leave the parking brake off to prevent it from seizing. Use wheel chocks instead.
- Prop open the trunk and hood slightly to allow air circulation and prevent moisture buildup (if stored indoors).
- Make a note of all the steps you took to prepare the car for storage, so you can easily reverse them in the spring.
Bringing Your Car Out of Winter Storage
When spring finally arrives and it's time to resurrect your car, take your time and carefully reverse the steps you took to prepare it for storage. Check all fluid levels, inspect the tires, and reconnect the battery. Start the engine and let it idle for a few minutes before driving. Listen for any unusual noises and check for any leaks. With a little preparation and care, you can ensure your car emerges from winter storage in top condition, ready to hit the road.
