What if Buick Hideo is noisy?

Solution to Buick Hideo Noise: The main source of Hideo noise is engine noise. Generally, the method to reduce noise is to replace the better engine oil, and the simplest method is to soundproof the intake, exhaust and cylinder head with cotton pads. If there is a lot of noise when idling, it is likely that the throttle, air intake and fuel injector of your car have been cleaned, especially the throttle. Engine noise is mainly transmitted to the cockpit through the firewall and the front floor of the cab. Of course, four doors and firewalls can also be soundproof. To achieve the best sound insulation effect, the sound insulation of the whole vehicle is needed, which requires a relatively high cost.
