Extreme temperatures, whether sweltering hot or freezing cold, can wreak havoc on church vehicles. Cold weather, in particular, isn’t just inconvenient—it can be downright deadly if regular maintenance hasn’t been addressed.
And because church vehicles typically aren’t used every day, they can often get overlooked. To avoid unnecessary risks, it’s essential to winterize your bus, shuttle, or van and prepare it for icy conditions.
Below are 10 critical steps to ensure your fleet remains safe and operational throughout the colder months.
- Check Both Batteries
Winter is notorious for draining batteries faster than usual, and a bus that doesn’t start in freezing temperatures could jeopardize passenger safety. Start by inspecting your batteries for any corrosion on the terminals, as this can interfere with electrical flow. Ensure both batteries are fully charged and capable of holding that charge over time.
Weak batteries are particularly vulnerable in cold weather and could fail without warning. Don’t forget that a failing battery might also impact vital equipment, such as your vehicle’s wheelchair lift, leaving it inoperable during a critical moment.
- Coolant Protection Level
Coolant isn’t just about preventing overheating in summer—it’s a crucial safeguard against freezing in winter. When temperatures drop below freezing, low or inadequate coolant levels can lead to the liquid freezing in the system. This could result in severe internal engine damage, leaving your vehicle inoperable.
Check the protection level of your coolant using a hydrometer to ensure it is mixed at the right ratio for cold weather. Topping off or replacing your coolant now is far less costly than addressing a cracked engine block later.
- Check the Front Factory Heater
A functional heating system isn’t just a comfort feature—it’s essential for safety and passenger satisfaction. Before sending your bus on a winter route, ensure the front factory heater is working properly. Turn it on, check that warm air is blowing out, and observe the blower speed.
A malfunctioning heater can make rides unbearable, especially during long commutes. Address any issues promptly to keep passengers comfortable and safe from extreme cold.
- Inspect Rear Heater and Valves
The rear heater system deserves just as much attention as the front. Rear water valves, which allow hot water to circulate, can sometimes be left in the off position. Double-check that these valves are turned on and functioning correctly.
Additionally, inspect the blower fan for any debris that might obstruct its operation. A clogged or non-functional rear heater can lead to uneven heating throughout the bus, making for a miserable ride.
- Re-Seam and Check Caulking
Over time, snow and ice can wreak havoc on your bus’s exterior, especially if there are cracks in the caulking. Water leaks caused by damaged or missing caulk can seep into the interior, damaging the floor and potentially causing electrical issues.
Inspect all seams and joints, looking for signs of cracking or missing pieces of caulk. Reseal as necessary to prevent moisture intrusion and protect the vehicle’s structure and systems.
- Inspect Tires
Your tires are your first line of defense against slippery, icy roads. Begin by checking the tread depth—tires with insufficient tread are more likely to lose traction in snow and ice. Most experts recommend a tread depth of at least 4/32 inches for winter driving.
Also, ensure your tires are properly inflated, as cold weather causes air pressure to drop. Low tire pressure not only affects handling but also increases the risk of blowouts. Finally, inspect the tires for signs of dry rot, which can lead to sudden failures.
- Test Brakes
Good brakes are a non-negotiable safety feature, especially when winter driving conditions come into play. Check that the brake pads have sufficient lining and that the rotors aren’t rusted or warped.
Rusty rotors can reduce braking efficiency and increase stopping distances—a dangerous combination on icy roads. Any signs of wear or damage should be addressed immediately to ensure your vehicle is ready to stop safely when needed.
- Inspect Windshield Wipers
Winter weather often brings snow, ice, and freezing rain—all of which can severely impact visibility. A good pair of windshield wipers is your best ally in such conditions. Inspect the wiper blades for cracks, tears, or wear, and replace them if necessary.
Make sure they’re properly installed and capable of clearing the windshield effectively. Consider upgrading to winter wiper blades designed to handle heavier ice and snow.
- Check All Lights
Visibility is critical in winter, both for drivers to see and for others to see your vehicle. Inspect all interior and exterior lights to ensure they’re functioning correctly. Replace any burnt-out bulbs and clean dirty or foggy light covers to maximize brightness.
Don’t forget to check turn signals and brake lights as well, as these are essential for communicating with other drivers on icy roads.
- Stock Emergency Equipment
Even with the best preparation, emergencies can still happen. Equip your bus with an emergency kit that includes an ice scraper, jumper cables, an emergency blanket, flares, and reflective triangles. These items can make a world of difference in the event of a breakdown or other unexpected situation.
Many of these tools are available in pre-assembled kits, which can be conveniently stored onboard for quick access.
Taking these steps not only ensures the safety of your passengers but also protects your vehicle from unnecessary wear and damage. Winterizing your fleet isn’t just a recommendation—it’s a critical responsibility for anyone operating in cold climates.
With proper preparation, you can avoid the headaches and dangers of winter weather while keeping your operations running smoothly.
