In order to assist technicians to undertake air conditioning (AC) system maintenance and repair with confidence, Nissens has launched a short video that provides them with useful, step-by-step guidance, on how to correctly diagnose and replace the thermal expansion valve (TXV) in an AC system.

The video explains how to recognise common symptoms of a faulty TXV, how to replace a faulty TXV and what the most important AC service procedures accompanying the replacement are.

A Nissens spokesperson said: “As the dedicated automotive systems specialist, Nissens Automotive supports the independent sector by sharing its valuable expertise.

“The goal is to spread quality technical knowledge and proven, best-practice principles that will enhance the reputation of workshops and their business competitiveness.”

Alongside the video, Nissens provides technicians with a huge archive of additional technical support.
