Replacing the hydraulic rod of the engine hood is a relatively simple process that requires certain skills and tools. The following are the general replacement steps for your reference:

1、 Preparation work

Tool preparation: Ensure that you have the necessary tools, such as a 17mm wrench or socket wrench set, screwdriver, etc.

Vehicle parking: Park the vehicle on a flat and open ground to provide sufficient space for operation.

Safety check: Open the engine hood and check the connection points and installation method of the hydraulic rod to ensure that other components are not damaged during operation.

2、 Disassemble the old hydraulic rod

Find the hydraulic rod: The hydraulic rod is usually located at the front of the engine compartment and connected to the front cover of the car. It may consist of one or two poles, depending on the vehicle model.

Release pressure: Before disassembly, ensure that the pressure inside the hydraulic rod has been released. This can be done by opening the hood and waiting for a period of time.

Dismantling bolts: Use a wrench or socket wrench to unscrew the bolts that secure the hydraulic rod. These bolts are usually 17mm in size and require careful handling to avoid damage.

Remove the old hydraulic rod: Once the bolt is unscrewed, the old hydraulic rod can be gently removed from the hole. Be careful not to damage the hoses or other components connected to it.

3、 Install a new hydraulic rod

Clean connection points: Use a clean cloth or brush to clean the connection points to ensure that the new hydraulic rod can be installed correctly.

Install new hydraulic rod: Align the new hydraulic rod with the connection point and secure it with screws and nuts. Pay attention to the accurate direction and installation position of the hydraulic rod.

Reconnect hoses and other components: Check if the hoses and other components connected to the hydraulic rod are correctly reconnected. If necessary, a wrench or screwdriver can be used to help connect.

4、 Inflation and testing (if applicable)

Inflation: If the hydraulic rod is inflated, it is necessary to find the inflation valve and use specialized tools according to the manufacturer's recommendations to inflate the hydraulic rod to the appropriate pressure.

Test: After restarting the engine and driving a certain distance, check if the hydraulic rod is working properly. Ensure that the hood can be fully opened and closed, and slides smoothly during the opening and closing process.

5、 Precautions

Follow the manual: For specific operations, please refer to your car repair manual or consult a professional technician.

Safety first: During operation, please ensure that the vehicle is in a stable state and avoid causing harm to the vehicle or yourself.

Save parts: During the disassembly process, please properly store screws, nuts, and other parts for use when installing new hydraulic rods.

By following the above steps, you can successfully replace the hydraulic rod of the engine hood. If you encounter any difficulties or uncertainties during the operation, please consult a professional in a timely manner.
