Prevents Housing Coolant Leaks for Improved Reliability

The stock thermostat housing on the 7.3L Powerstrokes is a constant source of coolant leaks that can lead you to spend a ton of cash on coolant or leave your 1999 to 2003 F250 or F350 7.3L high, dry, and overheated. One of the better solutions on the market is Sinister Diesel's Billet Aluminum Thermostat Housing. This complete housing assembly drops right into place of the stock thermostat housing, but it's almost entirely resistant to cracking and warping due to its stout design and construction. Sinister's billet thermostat housing is an excellent way to keep your coolant in your truck and keep your 7.3L Powerstroke running at its best.

CNC Machined Billet Aluminum Design that Accepts the Stock Thermostat

The thermostat housing was carefully designed by Sinister Diesel to drop right into place of your factory housing while providing a huge improvement in reliability. Unlike the stock housing which was made from low-quality stamped steel that can warp over time, Sinister's housing is made from CNC machined 6061 billet aluminum that's lighter, stronger, and more heat-resistant than stamped steel. Sinister tops each of their thermostat housings off with an anodized blue finish to protect against corrosion and keep the housing seated and fitting perfectly for years. The housing is entirely compatible with your stock thermostat, making it a hassle-free upgrade.
