Jeep Renegade heat gauge spikes temporarily resolved by turning on heater on Jeep Renegade

Some Jeep Renegade owners report experiencing temporary spikes in the heat gauge, which can be alleviated by turning on the heater. This phenomenon occurs because the heater draws heat away from the engine, leading to a temporary drop in operating temperature that is reflected on the gauge. While this can serve as a quick fix, it is crucial for owners to address the underlying causes of these temperature spikes to prevent potential long-term issues with the vehicle's cooling system.
