Using the Mishimoto fan shroud kit for your Honda S2000 is easy. First, make sure your engine is cool. Then, remove the old fan shroud. Place the new Mishimoto shroud in its place. It fits directly like the original part, so it should go in smoothly. When driving, this shroud will do its job of keeping your engine cool. As for maintenance, regularly check the shroud for any signs of damage, like cracks or loose parts. If you see any issues, replace it right away. Also, keep the area around the shroud clean to ensure good air flow. That's all you need to do to get the most out of your Mishimoto fan shroud kit.
