Using your Mishimoto Radiator Fan Shroud Kit is easy. First, make sure your engine is cool. Then, locate the radiator in your 2003 - 2006 Nissan 350Z. The kit comes with factory plugs for a direct plug - n - play installation. Just connect the fans and shroud to the appropriate spots on the radiator and use the included mounting hardware to secure everything. As for maintenance, keep an eye on the adhesive protective strip. If it starts to come loose, you can try re - applying it. Also, check the fans regularly to ensure they're spinning freely. Remember, this kit is compatible with both OEM and Mishimoto radiators, but always make sure the fit is correct. If you have any issues, you're covered by the Mishimoto Lifetime Warranty.
