Use 320-grit sandpaper to sand the scratched area, then apply scratch filler to level out the depression caused by the scratch. After the filler has dried, use 600-grit sandpaper for wet sanding on the filled area until it is roughly smooth. Before using the touch-up pen, shake it 20-30 times to ensure the paint is well mixed. After cleaning the area to be painted with a cloth, you can start painting. At least 3-4 coats of paint are required. Use 2000-grit sandpaper to sand the painted area, and finally wax and polish the repaired area.

Where is the thermostat located in a sedan?

Automobile thermostats are located at the upper water outlet of the engine. Here is relevant information about automobile thermostats: 1. Working principle: An automobile thermostat is a valve that controls the flow path of engine coolant. It automatically adjusts the amount of water entering the radiator based on the coolant temperature to ensure the engine operates within an appropriate temperature range, which can help save energy and more; 2. The thermostat mainly used in engines is the wax-type thermostat, which controls the coolant circulation method through the thermal expansion and contraction principle of the paraffin inside it; 3. Precautions: The thermostat must maintain good working condition; otherwise, it will affect the normal operation of the engine. If the thermostat opens too late or even fails to open, it will cause the engine to overheat; if it opens too early, it will prolong the engine warm-up time, resulting in the engine temperature being too low.
