When replacing a component in the engine cooling or air conditioning system, attention is often focused only on the main part.
Radiator, condenser, compressor.

However, there is a much smaller element that determines the sealing of the entire system: the o-rings and gaskets.

O-rings and gaskets operate under demanding conditions!
Heat, vibrations, and continuous contact with fluids and refrigerants reduce their elasticity and sealing performance over time. Reusing compressed or hardened seals can lead to micro-leaks and pressure drops, even after installing a new component.

For this reason, replacing seals is not just an installation detail, but a key part of the correct procedure.
AHE and 4Seasons components are supplied, where required, complete with o-rings and gaskets to ensure a safe and trouble-free installation!
