Identifying key areas of concern for cold weather

Several areas of your classic car require special attention during winter. The cooling system is particularly vulnerable, so ensure the antifreeze is at the correct concentration to prevent freezing and potential engine damage.

Tyres can develop flat spots if left stationary for long periods. To prevent flat spots, inflate your tyres 10-15 psi higher than usual and store your classic on tyre savers. Alternatively, move the car slightly every few weeks if possible.

A silicone-based lubricant protects rubber seals and gaskets from drying out and cracking. Then, consider using a breathable car cover to allow air circulation while keeping out dust and moisture.

Preparing for winter storage

Proper winter storage is crucial for preserving your classic car’s condition. Taking the appropriate steps will protect your prized vehicle from damage and ensure it’s ready to hit the road when spring arrives.

Selecting the right storage facility

Choose a secure, dry storage facility for your classic car. Look for climate-controlled options that maintain consistent temperature and humidity levels. This helps prevent rust and mould growth.

Ensure the facility has adequate space for your vehicle. You’ll want room to move around and perform maintenance tasks if needed.

Consider facilities with 24/7 access. This allows you to check on your car periodically throughout the winter months.

Ask about pest control measures, too. Rodents can cause significant damage to wiring and upholstery if left unchecked.

Creating an ideal environment for your classic car

Before storage, thoroughly clean and wax your car. This protects the paint and makes spring prep easier.

Top up your car with premium fuel and add a fuel stabiliser to prevent degradation. Then, check and top up all other fluids, including antifreeze.

Inflate the tyres to the recommended pressure. To prevent flat spots, consider placing the car on axle stands or tyre savers.

Use a high-quality, breathable car cover to protect against dust and moisture. Avoid plastic covers that can trap condensation.

Finally, desiccant bags should be placed inside the car to absorb excess moisture. Change these periodically throughout the storage period.

Security measures during winter months

Install a battery maintainer to keep your car’s battery charged. This prevents battery degradation and ensures your car starts when needed.

Remove valuable items from the car and store them separately. Then, consider using a steering wheel lock or additional immobiliser for extra security.

Inform your insurance provider about the storage arrangement. Some policies offer reduced rates for vehicles in long-term storage.

Lift the windscreen wipers off the glass to prevent the rubber from sticking and deteriorating. Then, if possible, check on your car regularly. This allows you to spot and address any issues early.

Maintenance tasks before winterisation

Proper maintenance before winter storage is crucial for preserving your classic car. These tasks will protect vital components and ensure your vehicle is ready for spring.

Changing fluids and oils

Start by changing your classic car’s engine oil and filter. Fresh oil prevents corrosion and protects internal engine parts during storage. Don’t forget to top up the coolant with a suitable antifreeze.

Maintaining leather and upholstery

Proper care of your classic car’s interior prevents cracking, fading, and mould growth during storage. Start by thoroughly cleaning all surfaces, including leather seats, carpets, and dashboard.

Next, apply a quality leather conditioner to prevent drying and cracking. For fabric upholstery, use a fabric protector spray to guard against moisture and stains.

Place silica gel packets or a dehumidifier inside the car to absorb excess moisture. This helps prevent mould growth and musty odours.

Consider using seat covers and a steering wheel cover for added protection. These shield vulnerable surfaces from dust and UV rays that may enter through windows.

Lastly, leave the windows slightly cracked to allow air circulation. However, ensure the gap isn’t large enough for pests to enter. This helps prevent moisture build-up inside the vehicle.

Engine and fuel system preservation

Protecting your classic car’s engine and fuel system during winter storage is crucial. Proper preparation prevents corrosion, fuel degradation, and other issues arising from extended periods of inactivity.

Using fuel stabilisers

Adding a fuel stabiliser to your tank is essential before winter storage. This additive prevents fuel from deteriorating and forming harmful deposits.

Pour the recommended amount into your fuel tank, then run the engine for a few minutes to circulate the treated fuel throughout the system.

fuel stabilisers typically keep petrol fresh for up to 12 months. They protect against oxidation and prevent the formation of gum and varnish deposits in the fuel system.

For optimal results, fill your tank before adding the stabiliser. A full tank reduces the air space where moisture can condense, further protecting your fuel system from corrosion.

Dealing with engine fluids

Change your engine oil and filter before storage. Fresh oil prevents contaminants from settling and damaging engine components during inactivity.

Then, check and top up your antifreeze mixture. A 50/50 blend of antifreeze and water provides optimal protection against freezing and corrosion.

Consider using a fogging oil in the engine cylinders, too. This creates a protective coating on internal engine surfaces.

If you’re storing your car in extremely cold conditions, remember to drain the coolant system and refill it with the proper antifreeze mixture to prevent damage from freezing.

Caring for the carburettor and fuel lines

Empty the carburettor float bowls to prevent stale fuel from gumming up the system. Turn off the fuel tap and run the engine until it stops.

Next, disconnect the fuel line and drain any remaining fuel. This prevents degraded fuel from clogging the lines and carburettor jets.

Seal all openings to the carburettor with tape or small plastic bags. This keeps moisture and debris out during storage.

Finally, consider using a fuel system cleaner before storage to remove any deposits or contaminants from the carburettor and fuel lines. Then, inspect all fuel lines for cracks or wear. Replace any damaged lines to prevent leaks when you bring your classic car out of storage.

Electrical system maintenance

Proper care of your classic car’s electrical system is crucial for winter storage. Focusing on battery health and preventing system drainage will ensure your vehicle starts reliably come spring.

Implementing battery maintenance techniques

Consider using a battery tender or conditioner to maintain your classic car’s battery during winter. These devices keep the battery charged without overcharging, which can damage its cells.

Before storage, clean the battery terminals and apply a thin layer of petroleum jelly to prevent corrosion. If you’re not using a battery tender, disconnect the negative terminal to prevent parasitic drain.

Remove the battery entirely and store it in a cool, dry place for long-term storage. Check the electrolyte levels in non-sealed batteries and top up with distilled water if needed.

Preventing electrical system drainage

Specific components can slowly drain the battery even when your car is off. To prevent this, start by ensuring all lights, including the boot and glove box, are switched off.

Remove any aftermarket electronics that might draw power, such as stereos with memory functions or GPS trackers. If removal isn’t possible, disconnect their power supply.

Consider installing a battery cut-off switch. This switch isolates the battery from the electrical system, eliminating potential drains.

Lastly, if your classic car has a mechanical clock, stop it to prevent unnecessary power consumption during storage.

Post-winter resurrection techniques

Reviving your classic car after winter storage requires careful attention to detail and a systematic approach. Proper recommissioning and thorough system checks ensure your cherished vehicle is ready for the open road again.

Recommissioning your classic car
