Extreme weather, both hot and cold, can have a significant impact on your car’s starter and overall starting system. In cold temperatures, engine oil thickens, making it harder for the starter motor to turn the engine over. This extra resistance can cause the starter to work harder than usual, leading to faster wear and tear. Additionally, cold weather can weaken the battery, reducing the power available to the starter and making starting the engine more difficult.

On the other hand, extreme heat can also take a toll on the starter. High temperatures can cause electrical components to overheat, leading to increased resistance in the starter motor’s wiring. Heat can also damage the solenoid, making it harder for the starter to engage properly.

In both cases, preventive maintenance is key to ensuring reliable starts. Keeping your battery in good condition, using the correct engine oil for your climate, and parking in a garage or shaded area during extreme weather can help protect your starter. If you experience persistent starting problems related to weather conditions, a starter-replacement may be necessary to ensure your vehicle remains dependable in any climate.
