Note
This item is for Manual Transmission vehicles. For automatic applications, please purchase optional Mishimoto Universal Transmission Cooler Kit.

Caution:
The provided Mishimoto radiator cap should replace the stock cap located on the expansion tank. The stock cap attached to the radiator should be installed on the Mishimoto Performance Aluminum Radiator. The Mishimoto radiator cap is a two-way valve, while the stock radiator cap is a single valve. Due to the difference in construction, the Mishimoto cap cannot be used on the radiator. If the Mishimoto cap is fit on the radiator, overheating may occur.

It is the installer's responsibility to check all thermostat plugs, NPT plugs, line fittings, and other connections to assure they are fully tightened before operating the vehicle. Mishimoto recommends that you check all connections at regular intervals, especially during the first few miles after installation. For additional technical information, contact sales@mishimoto.com.
