Volvo 240

On a 1993 Volvo 240, the low-pressure air conditioning port is located on the accumulator, which is situated on the passenger side of the vehicle, near the firewall. The port is typically covered by a plastic cap and is smaller in diameter compared to the high-pressure port. To access it, you may need to remove any surrounding components for better visibility.

Volvo engine braking works by utilizing the engine's compression to slow down a vehicle, primarily in heavy-duty trucks. When the driver releases the accelerator and engages the engine brake, the engine’s exhaust valves are opened, allowing compression resistance to slow the engine down. This process reduces wear on the brake system and provides better control on descents, enhancing safety and efficiency. The engine braking feature is especially useful in managing speed without overheating the traditional brake components.

To remove the fuel pump on a Volvo 240, first, ensure the vehicle is turned off and the fuel system is depressurized by removing the fuel pump relay or fuse and starting the engine until it stalls.
