This SECRET Will Make Your Car’s Heat Blow Twice as Hot (Costs Under $25)

This SECRET Will Make Your Car’s Heat Blow Twice as Hot (Do This Before Winter) If your car heater only blows lukewarm air, don’t assume you need an expensive heater core. In this video, we show the first things to check before winter: coolant level, trapped air in the cooling system, thermostat problems, cabin airflow, clogged heater cores, and blend door issues. You’ll also learn a simple two-hose test that can help separate a clogged heater core from a problem behind the dashboard. Start with the cheapest checks first, and only move to the expensive repairs if the basics are good. If your heater is weak, cold at idle, hot only on the highway, or hot on one side, this video will help you figure out where to start. #CarHeater #CarMaintenance #WinterCarTips #HeaterCore #Coolant #MechanicTips #DIYCarRepair
