💡 How does drawing a deep vacuum prevent overheating when replacing antifreeze? Pulling negative pressure out of the block removes trapped gas before fresh fluid arrives, letting atmospheric weight push the mixture down evenly through every passage. This handy approach keeps the cooling path completely sealed so heat transfers properly instead of cooking the engine over. - Lowering the block pressure below twenty five inches drives dissolved air straight out of the heater core and water pump - Fresh glycol settles into low spots instantly since nothing blocks the flow past the thermostat valve - Closed loop bleeding strips rust sludge from the drain pan while keeping fresh coolant pure inside the radiator tank
