Winter weather can be tough on your vehicle’s heating and cooling system. While many drivers associate cooling systems with summer, these components are just as important during cold weather. A properly functioning system keeps your engine at the correct temperature and ensures your cabin stays warm and comfortable.
At Ben Nielsen’s Springfield Auto Care & Fleet, we help Springfield drivers and fleet vehicles stay road-ready during winter. Here are some of the most common heating and cooling system problems we see—and how they’re typically fixed.
Weak or No Heat From the Heater
If your heater isn’t producing warm air, the issue is often low coolant levels, a clogged heater core, or a malfunctioning thermostat. Coolant transfers engine heat into the cabin, so leaks or circulation issues can reduce heating performance. Fixes usually include repairing leaks, flushing the system, or replacing the thermostat.
Engine Overheating in Cold Weather
Even in winter, engines can overheat. A stuck thermostat, coolant circulation issues, or internal blockages can prevent the cooling system from regulating engine temperature. Overheating should always be addressed immediately to prevent serious engine damage.
Coolant Leaks and Hose Failures
Cold temperatures can cause rubber hoses to become brittle and crack, leading to coolant leaks. Signs include puddles under your vehicle, frequent low coolant warnings, or a sweet smell from the engine bay. Replacing damaged hoses and repairing leaks early helps prevent overheating and loss of cabin heat.
Thermostat Problems
A thermostat stuck open can cause the engine to warm up slowly and result in weak cabin heat. If stuck closed, it can cause overheating. Replacing a faulty thermostat restores proper temperature control and improves system efficiency.
Defroster Not Clearing Windows
Your defroster relies on the heating system to remove fog and ice from the windshield. If it’s not working properly, visibility becomes a safety concern. Heater core issues, airflow problems, or coolant issues are often to blame and should be diagnosed promptly.
How to Prevent Winter Heating and Cooling Issues
Routine maintenance is the best way to avoid winter system problems. Regular coolant inspections, hose checks, and timely repairs help keep your heating and cooling system operating efficiently throughout the cold months.
