A restrictor is doing the same exact thing as an
open thermostat. It goes where the thermostat goes. it
looks like a washer sized to fit the thermostat
housing. It restricts the coolant flow,just the same as an
thermostat in the open position.(hot).
The difference
is,with a restrictor,the coolant is never held in the
engine (like a cold closed thermostat) untill it heats
to 195.
It can take its time and warm up
evenly,until the balance is met between coolant flow.
If
an engine is going to run hot,(besides for the
reason of the thermostat stuck shut) its going to do it
with a thermostat or a restrictor.
Heres
something you can try at home,for a car that likes push its
temp needle up..
Take your thermostat,and boil it
to see that its working properly.
If its good,
drill 2 3/8 inch holes,in it, so that water will always
flow through it.
Go and try to make your car
overheat.
If it does, drill 2 more holes,and repeat.
possibly, you'll find that you can drive a greater distance
before,the car begins to produce more heat than the cooling
system and entire chassis can dissipate.
Hows them
apples? :)
