How to align the timing marks on a Citroen C-Quatre?

The timing gear has a prominent tooth, and there are three teeth on the oil pump near the upper part of the timing gear. Align the prominent tooth on the timing gear with the middle one of the three teeth on the oil pump. Below is an introduction to the C-Quatre: 1. The Citroen C-Quatre comes standard with BS+EBD+EBA, ASR traction control system, Bosch 9.1 version ESP, and HAC hill start assist control system. The two flagship models also feature a tire pressure monitoring system. Except for the base Comfort trim, all models are equipped with a rear parking radar and rearview camera system. The top-tier flagship model additionally includes an auto-dimming rearview mirror for added convenience. 2. The 2018 C-Quatre retains its classic design while incorporating innovative elements. The continuous air intake grille connects seamlessly with the headlights, and the Citroen logo is naturally integrated into the design. The 'C'-shaped chrome trim smoothly links with the front grille and is separated from the turn signals, enhancing the front-end's cohesive appearance. The lower fog light area now includes widely used LED daytime running lights, significantly improving vehicle visibility in low-light conditions and increasing driving safety.
As an experienced auto mechanic, I think the timing mark alignment on the Citroen C-Quatre requires careful operation. For common engines like the 1.6L TU type found in this model, aligning the timing is crucial to synchronize the valves and ignition timing. The procedure involves several steps: First, ensure the car is parked on a level surface and the handbrake is engaged to prevent rolling. Then, remove the timing cover and use specialized tools like the camshaft locking pin and crankshaft timing pin to rotate the crankshaft to the top dead center (TDC) of cylinder one, where the marks should align. Next, precisely align the timing marks on both sides of the camshaft—they must match perfectly. Any misalignment can cause abnormal engine noises or power loss during operation. After alignment, reinstall the timing belt and adjust its tension. Once done, start the engine to check for normal sound. The entire process should be done slowly and meticulously, as even a minor mistake can lead to rough driving or accelerated wear on piston components. It's best to have an assistant or follow a video tutorial for guidance.
