Beans Diesel | 1999-2003 Ford 7.3 Power Stroke Billet Thermostat Housing w/ O-Ring and Bolts

The stock 7.3 thermostat housings are notorious for leaking coolant.  They are made from a thin press formed sheet metal that rusts, pits, and gets deformed by the bolts.  To fix the issue we have machined a new piece from 6061 aluminum.  This lets us build in a nice thick flange that will not flex or bend and also is much less susceptible to corrosion than steel. Made in Tennessee, USA Features: -Machined from 6061 billet for maximum strength-Greater corrosion resistance as well as great looks-Thicker O-ring for even better seal-New stainless bolts and washers for an excellent finished look -Made in USA  FITS: For 99-03 Only  Kit Includes: -Billet Thermostat Housing-O-Ring-Stainless Fasteners (3)
