Thermostat conversion kit – late model (aftermarket single-action 160 degree thermostat)
Assuming that your thermostat housing is in good condition, this kit will enable you to easily convert to our aftermarket thermostat. Enlarging the top 1/4″ of the mounting holes in your existing thermostat housing is the only real work involved.
After converting to a single-action aftermarket thermostat using this kit, you will still be able to use either an aftermarket double-action (Volvo type) or an OEM thermostat should you ever wish to do so.
The kit includes a 160 degree single action aftermarket thermostat (as described in product number CSTH_01_510, a 1/4″ spacer, two gaskets, two special 11/16″ shoulder nuts and a 17/32″ drill (which is used to modify the holes in your original thermostat housing). Installation will require a 3/8″ electric drill.
All single-action thermostats require a controllable restriction 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 restriction control in your bypass loop, you can find one in our online catalog with a product number of CSOT_01_61.
