Reische 07-09 Mustang GT 170 Degree High Performance Themostat

NOTE: Will only work in 2007-2010 3V vehicles.

Beware of aftermarket companies who sell the same thermostat for all Ford modular engines. Reische Performance thermostats are the only ones specifically designed to precisely fit each application, making them the best performing low temp units on the market! Whether you are using an aftermarket radiator or not these units will provide the best possible coolant temps and heat dissipation from your setup along with reduced warm up times and better cold weather performance when compared to a thermostat with holes drilled in the diaphragm. We believe the 170° opening temp is the ideal balance for high performance engines, providing high flow to your radiator by mid-180 temps while still maintaining a decent level of all season performance. With proper fan settings your cruising temps in cool weather will be in the 170s and in hot weather the 180s, giving those running high levels of timing and/or boost added protection against engine-damaging predetonation as well as maximum power output.

All Reische thermostats ship with a new O-ring, coolant ratio/additive recommendations and specific fan settings for popular handheld programmers. Fits 96-04 & 07-10 Mustang GT, 99-04 Lightning, plus most other Ford 4.6L & 5.4L SOHC apps. Compatible with Motorcraft RT1196 & RT1144.
