Using your Mishimoto Aluminum Coolant Expansion Tank is easy. First, make sure your engine is cool. Then, carefully remove the old coolant expansion tank from your vehicle. Install the new Mishimoto tank in its place, ensuring all connections are secure. You'll also need to install the included Mishimoto radiator cap. When it comes to the coolant, fill the tank up to the recommended level. Remember, this tank might not fit well with the stock air intake “S” hose, so it's best to use an aftermarket intake. For maintenance, regularly check the tank for any signs of leaks or damage. You can clean the outside of the tank with a mild cleaner to keep it looking great. With the Mishimoto Lifetime Warranty, you can enjoy peace of mind knowing your investment is protected.
