Stock plastic aluminum models of radiators normally will use the same cap style as the dealer original. Sometimes with certain foreign applications, the aftermarket radiator may use a different cap than stock. If you receive a part, and the cap does not fit, you can either visit your local parts store with the radiator. You can measure the radiator cap connection diameter and fit a cap based on their size. You can also contact us via a support ticket and we will respond with a cap number that will be stocked at your local parts store. Most of the parts we sell that may require a different cap will come with this information on the e-mailed invoice.
Our all aluminum racing radiators are built as close to OEM specifications as possible. Due to the high efficiency design and metal construction OEM radiator caps sometimes just don't cut it. If you purchase an all aluminum radiator, we suggest that you purchase a high pressure radiator cap with a locking mechanism. This will prevent small leaks around the cap area during use.
