Makes a lot of sense. So I don't see the need for a $100 - 160 degree sleeved
thermostat.

I took mine out this AM and replaced with Kees 178 degree sleeved unit.
Easy.

Anyone want a 160 degree, slightly used Moss Sleeved thermostat cheap????
:-)

PS: BTW, I put on K&N air filters on the BJ8 this weekend and the motor seems
to breath much better. Will know for sure when the snow is gone.  :-)

E. a 160 degree thermostat will not keep your coolant any cooler than a 180
thermostat once the coolant temp is above 180 degrees.  At or above 160
degrees coolant temp. the 160 degree thermostat is wide open. Above 180
degrees they are both wide open.
