Fluorescent tracing agent

Information
Volvo has introduced a fluorescent tracing agent into production.
The tracing agent is impregnated in a free standing "Dry-Water" cylindrical filter in the drying agent in the dryer.
The tracing agent dissolves and mixes with the compressor oil in the climate control system. The tracing agent is light green in color. It is used to identify any leakage in the climate control system. If an UV lamp is used, it is easier to see where the fluorescent tracing agent is leaking out.
The receiver drier is supplied without tracing agent for aftermarket orders.
Production receiver driers have a small decal indicating that they contain fluorescent tracing agent.
Cars in production will have a decal in the engine compartment indicating that there is fluorescent tracing agent in the car.
The location of the decal is the same for both aftermarket and production.
