How to remove the rear drain pipe of Buick LaCrosse

The steps to disassemble the rear drain pipe of Buick LaCrosse are as follows.

1. Just remove the clip and pull out the tube. Some models have special clips and are more difficult to remove. The inlet and outlet pipes of the small heater water tank are connected to the engine, and they are all buckled. You only need to remove the buckle to replace it.

2. Use water pipe pliers to remove the water pipe pliers and plastic pliers. Press the locking plate and pull out the warm water pipe. Pay attention to the high temperature and high pressure of the water. The pressure must be relieved first before removing the heating pipe.
