Thermostat and conversion kit with modified housing – late model (single-action 160 degree thermostat)
This kit eliminates the need to drill out the upper 1/4″ of the mounting holes in your existing thermostat housing. It’s the same kit as our basic aftermarket thermostat conversion kit (product number CSTH_03.2_411), except that the drill bit is replaced with a new, previously modified late model bronze thermostat housing.
All single-action thermostats require a manual valve in the bypass loop to provide the necessary back pressure through the block and head to enable the thermostat to control temperature. If you do not already have a manual valve in your bypass loop, you can find one in our online catalog with a product number of CSOT_01_61.
This kit is obviously ideal for those of you who may have already been planning to replace your old thermostat housing along with the thermostat.
