Abstract: A spring compressor including a first mating arm in configured to mate with a subframe component of a vehicle, a second mating arm configured to mate with a moveable suspension component of the vehicle, wherein the suspension arm carries a suspension spring, and an actuator configured move the second mating arm toward the first mating arm to compress the suspension spring, so as to facilitate installation of a part, such as a damper. The disclosure also provides a method of joining a damper or similar part with a suspension component, such as a suspension arm, and with a body portion of the vehicle, including mating the first mating arm with the subframe component, mating the second mating arm with the suspension component, actuating the actuator to move the second mating arm toward the first mating arm so as to move the suspension arm, and securing the damper to the vehicle.

Abstract: A pressure and prevacuum testing system for an AC system in a vehicle includes an air pressure source for pressurizing a cooling circuit of the AC system to a predetermined high pressure threshold and a vacuum source for prevacuuming the cooling circuit either to a predetermined prevacuum low pressure level or for a predetermined time period. The system also includes a pressure gauge for operatively measuring a pressure level in the cooling circuit. A controller is operatively connected to the air pressure source, the vacuum source and the pressure gauge. The controller compares the pressure level as measured by the pressure gauge to the predetermined high pressure threshold during a pressurized test of the cooling circuit and to the predetermined prevacuum low pressure level during a prevacuum test of the cooling circuit to determine if leaks are present in the cooling circuit.
