Steeda Coolant Tank

By: on 21 September 2019
I bought this polished aluminium coolant tank to improve the under bonnet appeal of my Mustang. It looks great, installation was super easy. Just 3 clamps and 2 bolts. It only took about 20 minutes. Unlike another coolant tank manufacturer the OEM cap fitted easily.
