What causes the loud engine noise after parking the Range Rover Velar?
2 Answers
Range Rover Velar's loud engine noise after parking is caused by the operation of the cooling fan. The specific reasons and solutions are as follows: Detailed explanation of the reasons: After parking and turning off the engine, the engine temperature does not drop immediately. At this time, the cooling fan needs to work to dissipate heat from the engine to prevent the accumulation of residual heat, which could easily damage the plastic components and wiring harnesses inside the engine compartment. In severe cases, it may even cause the vehicle to self-ignite. If the loud noise is not caused by the cooling fan, then it may be due to a damaged water pump. Solutions: One effective method to address the loud engine noise is to install soundproofing cotton. Engine noise is mainly transmitted to the cabin through vibrations from the hood and front fenders. Therefore, installing high-quality sound-absorbing foam materials on the engine hood can not only suppress vibrations caused by the hood but also absorb a significant amount of noise, making it very effective.
I've experienced this with my Velar too – hearing a buzzing sound from the engine bay after parking can be quite alarming. Most of the time, it's just the cooling fan running, especially in summer or after highway driving when the engine is hot. The fan automatically operates for a few extra minutes to cool things down. This is more noticeable in turbocharged models because the turbo needs cooling. Additionally, the exhaust system makes ticking sounds due to thermal expansion and contraction as metal parts cool down. However, if the noise is unusually sharp or lasts over 10 minutes, it could indicate low coolant, a stuck fan, or water pump issues – get it checked promptly to avoid engine overheating damage. Also, monitor your oil condition; overly dirty oil reduces cooling efficiency.
