The Citroen GS, a beacon of innovative automotive engineering produced from 1979 to 1986, continues to amaze with its distinctive hydropneumatic suspension that delivers an exceptionally smooth ride on our varied New Zealand roads. Understanding the intricacies of the GS’s design and addressing its unique maintenance needs is essential for preserving this iconic vehicle, ensuring it remains as remarkable today as it was at launch.
The most common issues on the Citroen GS relate to the hydropneumatic suspension system: leaks, sphere failure, and regulator problems. Rust is also a considerable concern. Engine issues can include carburettor problems and wear in the valve train. Parts can be difficult to source in New Zealand.
During a WOF inspection, the hydropneumatic suspension needs close examination. The car should rise and fall smoothly and maintain correct ride height. Brake performance is critical, as is the condition of the brake lines. Rust is a primary concern; inspect the floor pans, sills, and suspension mounting points. Steering play should be minimal.
The allure of the Citroen GS lies in its hydropneumatic suspension, which defines the way this vehicle performs on the road. However, this unique system requires regular attention. Essential maintenance includes LHM fluid changes and the meticulous inspection of the suspension spheres and pressure regulator to keep the driving experience exceptional. Additionally, owners should remain vigilant against rust, particularly in vulnerable areas such as the floor pans and sills. Engine reliability is generally a strong point, but carburettor and valve train wear may surface, necessitating timely intervention. To help maintain your GS’s performance, routine checks at service intervals, especially around 150,000km for the cooling system—where components like the water pump and thermostat can fail—are crucial.
