Having a part that cannot be fitted correctly can cause major issues, a damaged thread can happen in most expensive machines, especially where there is a lot of vibration. When in use, you wouldn't want it to break down, as this could be hazardous to life. A helicoil kit can be used for many different parts and machines to repair damaged threads. What is provided in a Helicoil Kit? The affected vehicles include the 2013-2015 Ford Fiesta, 2013-2015 Ford C-MAX, 2013-2015 Ford Escape, and 2014-2015 Ford Fusion.
The installation process can be time-consuming and complex, requiring precision and attention to detail. Did you know that spark plug Helicoil blew out is a common problem? If you’re experiencing engine problems, it’s important to take a look at your spark plugs and Helicoil.So, this is the normal diameter of the spark plug, and it’s going to make the diameter a little bit bigger, and then we screw it into the cylinder head with one of these three inserts. Once this insert is in place, we may thread the new spark plug into the insert. These inserts serve as threaded bushings or inserts that are inserted into a surface to establish a threaded hole. To helicoil damaged spark plug threads, first tap the hole, screw the helicoil onto the spark plug, apply sealant, and then insert and tighten the new helicoil securely. Bearing in mind I have only done spark plug threads on aluminium car engines; if there is a bit of build up on the bottom of the helicoil and you put a fresh spark plug in it can drive the helicoil further in but it is unlikely to pull it out as you unwind it as that tends to spread the helicoil against its outer thread. For this reason I did not pass the helicoil tap all the way down in the head, so the helicoil bottomed out on the uncut bit.
Restore stripped threads easily and permanently with Heli-Coil ® thread repair kits and master sets. Heli-Coil ® application-specific thread repair kits make complex repairs manageable and are often the recommended solution by both domestic and foreign automakers.

Here’s a pro tip that will make your life simpler: before beginning drilling, grease the drill bit with grease. This will catch all metal shavings that come off during drilling and ensure none fall into the cylinder. The primary cause of a spark plug coming loose is insufficient torque. When a spark plug is installed, it needs to be secured in place with a torque wrench. If the spark plug is tightened too loosely, spark plug won’t stay in place and the connection will be intermittent. This can cause misfires, decreased performance, and other issues. Why did my spark plug blow out of my engine? A: Helicoiling damaged spark plug threads requires a certain level of mechanical skill and knowledge. It is recommended to consult a professional mechanic for this type of repair. They have the necessary tools and experience to properly Helicoil the damaged threads and ensure a secure repair. Q: What tools do I need to Helicoil damaged spark plug threads? Installation Tool - This is a marker to identify the depth of the hole needed to be threaded, it also holds the new insert, so this can be screwed into the hole.
There are a few reasons why your spark plug may blow out of your engine, and understanding these causes can help you determine how to prevent it from happening in the future. If the spark plug can’t move, it’s less likely that the gas is going to get burned out of both ends before it fires. A: The process of helicoiling damaged spark plug threads involves tapping the hole to create new threads, inserting the helicoil insert, and then installing the coil with a coil installation tool. This creates new, properly threaded spark plug threads in the hole. It is important to follow the specific instructions provided with your helicoil repair kit for the proper steps to Helicoil the damaged threads. Q: Can I Helicoil a stripped spark plug hole in an aluminum cylinder head? Inserts are made out of hard stainless steel with diamond shaped wire, they have a notch for easy snapping and a tang so that it hooks onto the tool for easy insertion. Once you select the correct insert size for your spark plugs, apply Loctite. It is essential that the new insert stays secure when taking out the spark plug.
TOP TIP: To avoid the fancy tool, a simple and cost effective way to know how far to drill out a damaged thread is to measure the depth of the hole and mark this on the drill. You can use tape around the drill bit so you know where you need to drill to. You may want to use a vice to hold parts in place. It is essential to clean all anti-seize from your machine before applying Loctite, as mixing them will cause irreparable damage. Loctite will ensure that the new insert installed in the next step remains securely in place. 11. Select and install the correct insert from the repair kit Once installed, helicoils provide the correct threads for original fasteners, thus allowing for secure and reliable connections. How To Helicoil Damaged Spark Plug Threads Clear the damaged threads with a standard drill. Up to M12 (½”) The kit will come with a Drill Bit. However to repair the spark plug as mentioned before no pre-drilling is needed.
Depending on the application, Helicoil repairs may not be suitable for high-temperature or corrosive environments. To select the proper drill bit for drilling a spark plug hole, take into account the size of wire your car uses and opt for a slightly larger drill bit – usually #80 or #70. 6. Start drilling the spark plug holeA: Yes, helicoids can be used to repair other types of damaged threads in addition to spark plug threads. They are commonly used in automotive and mechanical applications to repair stripped or damaged threads in various types of holes. In Conclusion In this step, you have exposed spark plug threads and must assess any damage. Remove all spark plugs that might have a damaged thread and assess the overall situation. When the crankshaft rotates, valves open and close precisely at the right time. You must rotate your drive chain until all valves have been closed – this part can be difficult, but be sure not to let metal shavings enter your cylinder! 3. Access the damage Place the insert on the installation tool and position the adjustable ring so that the tang is centred in the slot. Wind the insert in the hole twisting the new helicoil until it is secure, this should be half a turn below the surface. Then unscrew the tool so the insert is securely in place.
