It is vital to have proper handling and installation of accessories in your auto. An oversight on any part could lead to devastating effects that are costly to repair. Avoiding common errors when fixing your header bolt will have a positive impact. Here is a list of four common mistakes to avoid when installing an ARP header bolt.
Skipping Re-Torque
Most people fix the header bolt without considering the condition of the nut. Re-torque aims to ensure the nuts are not too tight or too loose. A tight stud could cause damage to the thread, and a loose stud could fall off. Re-torque will reduce the adverse effects brought by the inadequate tightening.
Use the manufacturer's guide on re-torque, especially if you are also installing a fire ring. Most companies recommend making the change when the engine is hot.
Not Applying Lube
Failing to lube an ARP bolt is another common mistake. The right lube will prevent thread galling and guarantee an even clamp load. If you are working with stainless steel bolts, apply the lube on the head and bearing surface of the stud. If a thread sealer is not used on the thread, ensure you apply the lube on the threads.
Oiled studs are ideal as they offer consistency and accurate results. Oiling helps the gasket to distribute the stress applied on the entire surface. Ensure the lube you use is compatible with the studs to ensure it offers the desired results.
Not Measuring
Bolts came in varying lengths and sizes. Failure to measure the studs to ensure you have the right size will compromise your project. When it comes to fixing the bolt, accurate size is paramount as it will warrant the installed ARP will work.
Since the bolt holes need different bolt sizes, install the right length to each hole, and leave room for expansion.
Using Old Bolts
ARP bolts will stretch when used since they are elastic. The purpose of stretching is to strengthen the clamping force. In some cases, the stretch is permanent, which makes it impossible to reuse it.
Reusing the stud will compromise the clamping force and torque due to overstretching. Besides, the overstretching, heat, and pressure could lead to the gasket blowing. Use new studs each time you are doing ARP installation to avoid such complications.
Improper installation of the ARP bolt could damage the head gasket. Before installation, start by reading the manufacturer's manual to have a clear understanding of how to handle the project. Contract an auto accessory expert to handle the ARP head bolt installation if you feel incompetent. Experts will handle the task as required and give you peace of mind.

Hi, my name is Scott and I’m an amateur mechanic. I don’t have a lot of spare cash so I recently bought a used car, which I’m fixing up myself with some help from a friend. I know that it’ll take some time to get things just the way I like them; I’m a bit of a perfectionist and I want my car to run well and look good. A few weeks ago, I started looking at car seat covers. I thought that this would be one of the easier jobs I had on my car but I hadn’t realised how many options there were to choose from! It took a bit of research, but I’ve now chosen some custom covers that I should be fitting soon. I started this site to hopefully help other car lovers who are looking for auto accessories.
