Reasons for Loud Engine Noise in Geely Freedom Cruiser

[LeAddyson]

Here are the reasons for loud engine noise in Geely Freedom Cruiser: Weather conditions: Cold weather causes the engine idle speed to increase, keeping the cold engine at a high RPM. Loose plastic parts in the engine compartment: Such as the engine cover, intake pipe, etc., which can be fixed by tightening. Incorrect engine oil condition: When the viscosity of the engine oil is too high, it can cause operational issues in the engine, reducing lubrication effectiveness and leading to friction during operation, which generates noise. Valve leakage: During the reaming of the valve seat, improper operation or excessive wear of the valve guide inner hole can cause the valve seat to tilt or the valve clearance to be too small, resulting in valve burning and incomplete sealing, leading to leakage.

Last time I drove my Free Cruiser, I encountered the same issue and found there are quite a few reasons for excessive noise. First, check the engine oil—if it hasn't been changed for too long and its viscosity has altered, poor engine lubrication can lead to clunking noises, especially during cold starts. Also, inspect the engine mounts; worn-out rubber pads can increase vibration noise, making the whole car feel shaky. Loose belts are another common issue—squeaky sounds usually come from them, so adjusting the tension is necessary. The exhaust system is another culprit; loose connections or leaks in the muffler can cause a whooshing noise. Carbon buildup is also something to watch out for—regular highway driving to clear carbon deposits is quite effective. All these factors could contribute to the noise, so it's best to troubleshoot them one by one.
