How to Evacuate the Car AC System without a Pump

Introduction: What is an AC system and how does it work?

The air conditioner is connected to the car’s engine cooling system. In the event of a heat wave or extremely humid climate, when the inside temperature becomes unbearable, drivers may be tempted to take off with the condensing unit disconnected. This can result in engine overloading and even damage if regular cooling water is not circulating. In order to prevent this, the system can be configured to use the AC’s accumulated ice to circulate water.
AC system : What is an AC system and how does it work?
An air-conditioning (also known as a refrigeration) system is composed of one or more cooling coils and evaporator coils (or cooling fins), which are located in the vehicle cabin. In addition, a compressor and an expansion valve may be integrated into the unit. The evaporator coil (also called a thermoelectric radiator) uses liquid (coolant) to absorb the heat from inside the cabin and condenses it into water vapor. The blower then distributes this warm air across the interior of the vehicle.

Evacuating an AC System without a Pump

It is a common practice for drivers to only charge the battery to start their car when the engine coolant temperature is below 100 degrees Fahrenheit. This allows them to leave their AC behind in order to save on power usage. However, if one were to start a car without charging its battery, it would be unable to run. This can result in overheating, engine malfunction and even damage in the case of an accident. The process of evacuating a car’s AC system without the use of a charger is not difficult but requires some practice.
In order to evacuate a car’s air conditioning system, one must first be aware of the position of the condenser and compressor. Afterward, they should turn off the drain cock on the radiator. One can find this at the bottom of the radiator near where it connects to the engine. They should also remove any rain gutters or covers that surround their engine. They must then locate their car’s high-pressure hose then disconnect it from its connections at both ends. Next, they should lay the high-pressure hose on the ground and cover it with a thick blanket. Finally, they should remove all of their vehicle’s fuses except for the fuses which control its radiator fans.
