What causes the abnormal noise in the Baojun 730 engine during cold starts?
2 Answers
Baojun 730 cold start engine abnormal noise is most likely caused by insufficient lubrication during cold starts. Below is relevant information about the Baojun 730: 1. Sufficient space: The Baojun 730 has a length of 4780mm, width of 1820mm, height of 1755mm, and an ultra-long wheelbase of 2750mm, giving it a very spacious interior compared to other vehicles in its class. 2. Excellent power: The Baojun now features a 1.5T turbocharged engine with the code name 260T, paired with a brand-new CVT transmission, while also being fuel-efficient.
I've been driving my Baojun 730 for a while now, and when starting the engine cold, it makes squeaking or rattling noises, commonly caused by issues with the valve lifters or timing chain. In cold weather, the engine oil's fluidity decreases, leading to insufficient lubrication of parts, which causes those metal components to rub directly against each other and produce noise. Additionally, aging belts or loose tensioners can also result in similar sounds. I recommend first checking if the oil viscosity is suitable for the local climate—too thick or too thin can both be problematic. Try switching to full synthetic oil, as it can improve startup lubrication. Regular maintenance is crucial; don't skimp on that bit of money, or prolonged noise could affect the engine's lifespan. My car had the same issue before, but after changing the oil, it improved significantly, and now it starts up quietly. In short, address such problems early to avoid small issues turning into big ones and wasting more money.
