Why does Wuling Hongguang always make a ticking sound?
2 Answers
The reasons why Wuling Hongguang always makes a ticking sound are as follows: 1. Cold engine noise: When starting a cold engine, you often hear a "ticking" noise from the engine compartment, which disappears after the engine warms up. This is because the car has been parked for too long, and the engine oil has mostly flowed back into the oil pan. During a cold start, the oil cannot form an effective oil film or establish proper oil pressure, causing slight metal impacts in either the hydraulic lifters or mechanical rocker arms. 2. Hot engine noise: When a noise occurs in a hot engine, the owner needs to pay close attention. Hot engine noises are generally difficult to locate and require technical troubleshooting. If the engine does not lose power or produce white/black exhaust when the noise occurs, the problem is relatively minor, and internal cylinder issues can be ruled out. Typically, belt slippage or aging can also cause noises. When a metal knocking sound is heard, the owner should promptly take the car to a repair shop for inspection.
I've been driving the Wuling Hongguang for over a decade to haul goods. The most common cause of the rattling sound is either excessive valve clearance in the engine or a loose timing chain. Over time, the chain wears out and produces a rhythmic knocking noise when rotating. If not addressed promptly, the wear can worsen, affecting power output. Loose chassis bolts can also cause noise, especially in the rear axle area, which experiences significant vibration when carrying heavy loads, making it prone to loosening. I recommend not waiting—take it to a repair shop to check the chain and chassis. Installing a chain tensioner or tightening the bolts should suffice and won't cost much. Safety comes first. Ignoring engine issues can be dangerous, as you might get stranded on the road, causing delays and hazards. During regular maintenance, pay attention to unusual noises—early detection and repair save trouble in the long run.
