How to put car refrigeration oil

In car maintenance, replacing refrigeration oil (also known as coolant) is an important maintenance task. Correct operation can not only extend the life of the engine, but also avoid failures caused by high temperatures. This article will introduce in detail the steps, precautions and related data for discharging automobile refrigeration oil to help car owners and maintenance personnel better complete this task.

1. Refrigeration oil discharge steps

1.Preparation: Make sure the vehicle is turned off and wait for the engine to cool down to normal temperature (to avoid burns).

2.Locate the drain outlet: The refrigeration oil drain port is usually located at the bottom of the water tank or on the side of the engine block. The specific location varies depending on the vehicle model.

3.Place oil container: Place an oil container under the discharge port to prevent refrigeration oil from polluting the environment.

4.Open the drain valve: Use a wrench or screwdriver to unscrew the drain valve and allow the refrigeration oil to flow out slowly.

5.Check emissions: After the refrigeration oil is completely drained, check whether there are any residues or impurities.

6.Clean up residue: Rinse the cooling system with clean water (optional) to ensure that no old refrigeration oil remains.

2. Precautions

1.Safety first: Wear gloves and goggles during operation to avoid freezing oil contact with skin or eyes.

2.Environmentally friendly treatment: Old refrigeration oil is hazardous waste and needs to be recycled by professional organizations.

3.Choose the right refrigeration oil: Choose refrigeration oil that meets the standards according to the vehicle manual and avoid mixing different brands or models.

4.Check system tightness: After the replacement is completed, check the cooling system for leaks.
