If you follow our Ford Powerstroke 6.0L product line, you are aware of the high- and low-temperature thermostats we released last year. The high-temperature unit quickly became a customer favorite as a reliable way to improve engine operation, in-cabin heat, and fuel mileage. These benefits are particularly useful in the cold-weather months. Our low-temperature thermostat offers a lower recovery temperature compared to the factory unit, which can help keep coolant temperatures regulated during towing or when transporting heavy loads.
During the release of the thermostats, we had numerous requests for a replacement housing. The factory housing is a casted piece, which isn't aesthetically pleasing, but it is easy to replace.
Development began in a pretty simple fashion. We acquired an OEM housing and started capturing measurements so that we could reverse-engineer the piece.
