The Besturn B50 chassis does not have drainage holes. The Besturn B50 has the following drainage holes: Fuel tank cap drainage hole, sunroof drainage hole, door panel lower drainage hole, trunk drainage hole, engine compartment drainage hole, and air conditioning drainage hole. Besturn B50 engine: Equipped with a 1.8L ET3 series high-performance all-aluminum engine, which is more fuel-efficient and has higher power performance compared to engines of the same displacement level. Available colors include Cloud Silver, Silver Pearl Black, Arctic White, Elegant Gray, and Agate Red. The Besturn B50 is equipped with an audio system configuration, an AUX interface, and USB, providing two external audio source playback functions.

As a veteran mechanic with over a decade of experience, I must say the drainage hole locations on the Besturn B50 are actually quite crucial. There are one or two small holes beneath each door specifically designed to drain accumulated water from the door panels; when you open the fuel tank cap, there's also a tiny gap to allow water drainage; while the sunroof's four corners connect to drainage tubes that run all the way to the undercarriage, which are particularly prone to getting clogged with leaves and mud. Near the base of the windshield wipers, there's an additional AC drainage hole that often gets overlooked during car washes. If these areas get blocked, water accumulation inside the vehicle can lead to mold growth, and the undercarriage welding points may rust through. I always remind car owners to have mechanics use compressed air to clear these passages during routine maintenance - it's much cheaper than fixing leaks later, especially during southern China's rainy seasons when more frequent checks are necessary.

As a veteran B50 owner with seven years of experience, let me tell you about the interesting distribution of drainage holes on the chassis. When washing the car, squat down and you'll clearly see small holes along the bottom edges of the doors where dust accumulates - you can easily feel the buildup with your fingers. The drainage channels inside the fuel filler cap often get clogged by spilled liquids during refueling. The sunroof drainage tubes run from the roof and exit near the rear wheels underneath. Last year when my sunroof leaked, I discovered the thin tube in the A-pillar was completely blocked by willow catkins - I eventually cleared it using flexible steel wire. Remember to test water flow through these holes with a syringe during seasonal changes; repairing chassis rust damage can cost 3,000 to 4,000 yuan.

The drainage holes of the Besturn B50 are mainly located in several key areas: small holes at the bottom edge of each door drain water seeping through the window gaps; do not overlook the drainage slots in the recessed area of the fuel tank cap; the sunroof drain tubes extend to the four corners of the chassis to form outlets; there are also drainage ports near the air intake for the air conditioning under the front windshield. If these areas are blocked by mud or fallen leaves, accumulated water can corrode the metal parts of the chassis. When cleaning, avoid using hard objects to poke; using a soft hose from an air pump to blow out debris is the safest method. Regular inspections can prevent moldy odors inside the car and also impact the resale value.
