Oil drain screw Type A, 13 x 1.5

An oil drain plug is an important sealing component on the oil pan (or more rarely directly on the engine block or transmission housing) of a vehicle or machine. Its main function is to securely hold the motor oil or transmission oil in the system while also allowing for a controlled draining of the oil during an oil change.

Structure and Use:

It typically consists of a screw head, a threaded part, and a sealing surface, which is usually fitted with a gasket (copper, aluminum, fiber) to ensure a leak-free connection.

It is used primarily in cars, motorcycles, trucks, and many other machines with an oil circulation system that require regular maintenance, such as compressors, generators, and construction machinery.

The biggest weak point is the thread, which can be damaged by repeated tightening and loosening, excessive torque, improper handling, or corrosion. This leads to oil leaks, which are not only harmful to the environment but can also lead to serious engine damage due to oil starvation. V-COIL oil drain plugs are designed specifically to solve this problem.

In the context of repairing damaged threads, there are various types. Your product, the Type A Oil Drain Plug, is a so-called oversize plug. It has a larger thread than the originally damaged plug and serves as a simple and quick direct solution.

How it Works:

If the original thread (e.g., M12x1.5) in the oil pan is defective, the hole is not repaired with a thread insert. Instead, this larger, self-tapping plug is simply screwed directly into it. The hole often needs to be slightly re-drilled before the plug cuts the new, larger thread.

Advantages of this Method:

• Quick and Easy: It is a very fast repair method that requires fewer steps than a thread repair with inserts.
• Direct Solution: No special installation tools or thread inserts are needed.

Disadvantages:

This type of repair can only be performed once or very limitedly, as a larger thread is cut each time. It is often a "last resort" solution before an oil pan must be replaced, or for less critical applications. For more permanent and repeatable solutions, thread inserts (also offered in the V-COIL system) are the better choice.

1. When should I use a V-COIL Type A oil drain plug?

This plug is ideal for a quick and straightforward repair when the thread of the original oil drain plug in the oil pan is damaged. It's a simple oversize solution that's perfect for DIY repairs.

2. Do I have to drill the hole before screwing it in?

In most cases, the damaged threaded hole must be drilled out slightly to make room for the larger M13x1.5 thread. The exact drill bit size depends on the degree of damage and the original thread diameter. Information can be found in the corresponding V-COIL kits.

3. Is this plug suitable for every oil pan?

No, this plug with the M13x1.5 size is specifically designed as an oversized repair solution for original M12x1.5 threads. It's important to know the original thread and ensure that the Type A plug is the correct oversize for your vehicle or machine.

4. What is the difference from a repair with a thread insert?

The main difference is the method. The Type A plug directly cuts a new, larger thread. A repair with a thread insert requires drilling, cutting a special STI thread, and then screwing in an insert. This method is more complex but allows for the use of a plug with the original dimensions and is more durable.

5. How often can I repair the thread with a V-COIL Type A plug?

Repairing with a Type A oversize plug is generally a one-time solution. Since a larger thread is cut with each repair, this method is only applicable a limited number of times before an oil pan must be replaced.
