What should you pay attention to with the oil cooler?

The oil cooler is usually installed in the front bumper, so it may be possible to modify the bumper, at least one hole that leads the air to the oil cooled surface. Because the oil cooling will change the pressure of the system, it is better to have an instrument to test the size of the change, and it will be better to see the change in the temperature of the oil. Oil cooling will store a certain amount of oil, so the first addition of oil is more.
