It's essential to take the right steps to ensure your trucks stay in top shape. Whether you're managing a small fleet or preparing a few rigs for downtime, proper preparation and maintenance can prevent costly repairs and headaches down the line. Here are eight must-know tips for long-term semi-truck storage that will keep your fleet ready to roll when you need it.
Choose the Right Storage Location
The first step in long-term semi-truck storage is selecting the right location. A secure, clean, and well-maintained facility protects your trucks from potential damage and theft.
If you’re storing your fleet outdoors, consider your location’s weather conditions. Trucks left unprotected in extreme heat, cold, or heavy rainfall can suffer from rust, wear, and other damage. Investing in covered storage or weatherproof tarps is a smart way to shield your vehicles from the elements.
Security is another critical factor. Ensure the storage area has surveillance cameras, controlled access, and proper lighting. The peace of mind you'll have knowing your fleet is secure is worth the effort.
Perform a Thorough Cleaning
A clean truck is more than a good-looking truck—it’s a protected one. Before storing your semi-trucks, thoroughly clean them inside and out. Dirt, grime, and road salt can cause corrosion over time, especially on metal components like the undercarriage.
Clean out the cab to prevent unwanted odors and pests. Remove all trash, vacuum the floors, and wipe down surfaces. Emptying food and drink containers is especially important to avoid attracting rodents or insects that could damage wiring and other components.
Finally, pay special attention to cleaning the exterior. Use a high-pressure washer to remove any debris from the wheels, axles, and undercarriage. Don’t forget to wax the truck’s exterior to add an extra layer of protection against rust and UV rays.
Inspect and Maintain Tires
Tires are one of the most vulnerable parts of a semi-truck during long-term storage. Extended periods of inactivity can cause flat spots, which lead to uneven wear and reduced performance when a truck reenters the workforce.
Before storing your fleet, inflate the tires on each semi-truck to the manufacturer’s recommended pressure. Check for signs of wear, cracks, or punctures.
If you notice any issues, address them immediately. Consider rotating the tires periodically during the storage period to prevent flat spots.
If possible, use wheel chocks instead of engaging the parking brake. This step prevents unnecessary pressure on the tires and ensures they remain in good condition. For longer storage durations, lifting the truck to take the weight off the tires entirely is an excellent option.
Protect the Engine and Fluids
The engine is the heart of your semi-truck, and neglecting it during storage can result in costly repairs. Start by topping off all fluids, including oil, coolant, and windshield washer fluid. Full reservoirs help prevent condensation and contamination.
Next, change the oil and filter before storing your truck. Old oil contains contaminants that can damage the engine over time. For diesel engines, consider adding a fuel stabilizer to the tank to prevent the fuel from degrading and causing injector issues.
Run the engine for a few minutes after adding the stabilizer to ensure it circulates throughout the system. This small step can help keep your engine healthy during storage.
Disconnect the Battery
Batteries can drain quickly when left unused, even if the truck isn’t running. To avoid dealing with a dead battery when bringing your truck back into service, disconnect it before storage. Remove the negative terminal first, followed by the positive terminal.
Store the battery in a cool, dry place away from direct sunlight. If possible, use a trickle charger to maintain its charge throughout the storage period. This step prevents sulfation, which can reduce the battery’s lifespan and performance.
Label the cables and terminals to make reinstallation easier when recommissioning the vehicle. Taking these steps ensures the battery stays ready to power up when needed.
Protect Against Pests
Rodents and insects can cause significant damage to semi-trucks in storage. They chew through wiring, build nests in air filters, and leave behind droppings that create additional cleanup challenges. Taking preventive measures can save you from these headaches.
Seal any openings where pests might enter, such as vents, exhaust pipes, and gaps around doors. Steel wool or mesh screens are effective for blocking access. Using mothballs, dryer sheets, or commercial rodent repellents inside the cab and engine compartment can help deter pests.
Check your stored trucks regularly for signs of infestations. Early detection allows you to address problems before they escalate.
Monitor Regularly
Your fleets will still require regular attention, even when placed in long-term storage. Schedule periodic inspections to check for any issues that might arise during inactivity. Look for signs of leaks, rust, or tire pressure loss.
Start the engine every few weeks and let it run for a short time. This act helps circulate fluids and keeps seals from drying out. However, avoid prolonged idling, as it can cause unnecessary wear.
If feasible, move the truck a short distance to prevent flat spots on the tires and test the braking system. These small actions help keep your trucks in working condition and reduce the time needed to prepare them for the road.
Prepare for Recommissioning
When you're ready to bring your fleet back into service, follow a systematic approach to ensure their driveability. Here are the most essential aspects of this process:
• Begin by reconnecting the battery and inspecting all fluid levels. Check for any signs of leaks or damage that may have occurred during storage.
• Inspect the tires for proper inflation and condition.
• Test the lights, brakes, and other safety systems to ensure everything functions correctly.
• Take the truck for a short test drive to identify any issues that need attention.
A detailed checklist can make this process more manageable and help you avoid overlooking critical steps. Proper preparation allows your trucks to return to the road with minimal downtime and less expense.
