Boulder Auto Repair

Winter in Boulder, Colorado, brings breathtaking snowy landscapes and plenty of opportunities for skiing at Eldora and the resorts on the I70 corridor, but it also delivers frigid temperatures that can wreak havoc on your car’s battery. Understanding how cold weather affects your battery and taking steps to maintain it can save you from the frustration of a vehicle that won’t start on a chilly morning.
