Do I have to remove the oil pan to use the repair kit?

In many cases you can repair the damaged oil drain screw thread directly on the installed oil pan after draining the oil and cleaning the area. Always check the condition and accessibility of the component.

Is the repair permanent?

If the new receiving thread is cut correctly and the new oil drain screw is tightened to the specified torque, the repair provides a durable and load-bearing connection for future oil changes.

Can I use the kit on aluminium oil pans?

Yes. The kit is particularly useful for aluminium oil pans, where the original threads can strip more easily. Proceed carefully and follow the vehicle manufacturer’s torque recommendations.

Do I need a torque wrench?

A torque wrench is strongly recommended to achieve the correct tightening torque specified by the vehicle manufacturer and to avoid overloading the new thread or the sealing ring.

What should I check after the repair?

After refilling the engine oil, check the oil drain area for leaks during the first warm-up cycle and re-check at the next service or oil change.

Step-by-step instructions

The following sequence describes the basic procedure. Always observe the vehicle manufacturer’s instructions.

Prepare the vehicle and drain the oil.
Safely lift and secure the vehicle. Place a drain pan under the oil pan and drain the engine oil completely.
Remove the old oil drain screw.
Unscrew the drain plug and clean the area around the damaged thread from oil and dirt so that you can work clearly.
Select the correct HexTap OS and cut the new receiving thread.
Choose the appropriate tap from the kit. Using a ratchet or wrench, cut the new receiving thread straight into the bore. Back off regularly to break the chips.
Remove chips and clean the sealing surface.
Carefully remove produced chips from the thread and sealing surface. Make sure that no swarf remains in the oil pan.
Install the new oil drain screw with sealing ring.
Select the matching screw and sealing ring from the kit. Lightly oil the threads, place the sealing ring on the screw and screw it into the new thread. Tighten with a torque wrench according to the vehicle manufacturer’s specification.
Refill oil and check for leaks.
Refill engine oil, start the engine briefly and check the drain area for leaks. Correct the torque if necessary.

Note: The exact procedure can vary depending on vehicle type. If you are unsure, contact a professional workshop.

Safety & good practice

Work only on a safely supported, secured vehicle.
Wear suitable personal protective equipment (gloves, safety glasses).
Dispose of used oil and oil filters according to local regulations.
Re-check the drain screw visually at the next service or oil change.

Frequently asked questions

Short answers to common questions directly at the vehicle.

1. Do I have to remove the oil pan for this repair?

In many cases no. After draining the oil and cleaning the area, the new receiving thread can be cut directly on the installed oil pan. Always check accessibility and the general condition of the component before you start.

2. Is this repair suitable for aluminium oil pans?

Yes. Aluminium oil pans are particularly prone to thread damage at the drain screw. The kit is well suited for these cases. Proceed carefully and always tighten with a torque wrench to the specified torque.

3. Do I really need a torque wrench?

A torque wrench is strongly recommended. It helps to achieve the correct clamping force, ensures a tight seal and reduces the risk of damaging the newly cut thread or the sealing ring.

4. How can I check whether the repair was successful?

After refilling the engine oil, let the engine run briefly and check the area around the drain screw for leaks. Also check again after the first drive and at the next service or oil change.

5. What else should I consider?

Always follow the safety instructions, use suitable tools and observe the vehicle manufacturer’s information. When in doubt, carry out the repair in a professional workshop or consult our technical support.
