Using the DRAG CARTEL K - SERIES Tensioner Cover Plate is easy. First, take off the OEM black cover from your engine. Then, clean the mounting surface thoroughly. You can use a razor blade to scrape off the old sealer, followed by a green scotch brite pad and brake cleaner for a good clean. After that, simply bolt on our cover plate with the new hardware that comes with it. You don't need to use any sealer. When it comes to checking the timing chain tensioner, with our cover plate, it's much quicker and easier compared to the OEM one. Remember, it's a good idea to check your tensioner every now and then for wear or damage. If you notice any issues, it's best to replace the tensioner right away. As for maintenance, just keep the cover plate clean and check the bolts regularly to make sure they're tight. That way, your engine will stay in good shape.
