How to align the timing of Citroen C-Quatre?
2 Answers
Citroen C-Quatre timing alignment method: 1. Remove the timing cover, slowly rotate the crankshaft, observe that each camshaft wheel has a hole, slowly rotate to align with the corresponding hole on the cylinder head, and fix the camshaft with a special tool; 2. The crankshaft positioning hole is located at the rear of the engine, there is a large hole, find the upper part of the transmission side near the right half-shaft, and insert a special tool to fix the crankshaft; 3. Adjust the tensioner wheel position properly, the tightness should be moderate to avoid noise, adjust the pointer to the middle position, use a hexagon wrench to adjust left and right to select the middle position and fix it, then tighten the screw. The C-Quatre is a model under Dongfeng Citroen, with body dimensions of 4282mm in length, 1773mm in width, and 1483mm in height.
For the timing alignment of the Citroen C4, I've changed the belt several times, and the steps are quite meticulous. First, you need to position the engine at the timing mark, use a crankshaft locking tool to secure the crankshaft in place, and then rotate the camshaft until the corresponding marks align. Don’t forget the engine on the C4 has specific notches—ensure precise alignment, or issues may arise. When installing the new belt, the tension should be just right—not too tight or too loose—about 90 degrees of twist by hand is ideal. I recommend replacing the water pump and tensioner pulley at the same time to avoid future wear. For tools, you’ll need a dedicated locking kit; regular wrenches aren’t stable enough. After alignment, manually turn the crankshaft two full rotations to check if the marks reset—don’t skip this step. Incorrect timing can cause engine gear clash, and severe cases may lead to bent valves, which are costly to repair. DIY beginners can start with video tutorials, but safety first—gloves and goggles are a must.
