Why does the Baojun 310 make a clanging sound when starting cold?
2 Answers
The reason for the clanging sound when starting the Baojun 310 cold is due to valve clearance noise, which is a normal phenomenon and does not require repair. The Baojun 310 is equipped with a 1.5L DVVT naturally aspirated engine and comes with a manual-automatic transmission, featuring paddle shifters and a rotary gear shift mechanism. In terms of appearance, the Baojun 310 automatic version has been upgraded with dual-tone alloy wheels, giving the overall design a cool and dynamic look. The dimensions of the Baojun 310 are 4032mm in length, 1680mm in width, and 1450mm in height, with a wheelbase of 2550mm. The front face design inherits and enhances the Baojun brand style, with the front grille perfectly balancing aesthetic design and functional needs. The chrome grille trim extends to the lower edge of the headlights, and the prominent Baojun logo on the grille gives the vehicle a clean and sharp appearance.
My old buddy Baojun 310 sometimes makes a clanking noise during cold starts, which sounds quite annoying. This is usually caused by insufficient lubrication of metal parts when the engine is cold. I've encountered similar situations before and suspect it might be due to excessive piston clearance or loose valve stems. When the engine oil has poor fluidity during cold starts, component friction increases, leading to noise. I suggest you first pop the hood to locate the noise source - if it's coming from the top of the engine, it might be oil-related; if from the side, perhaps a slipping belt. Don't delay, check the oil level and quality promptly. Using thinner oil in winter can alleviate the issue. During maintenance, have the mechanic check belt and chain tension. Warming up the engine for a few minutes before driving can prevent many abnormal noises. I make it a habit to change oil every season to reduce such troubles - safety first, after all.
