66 - 98 engines
The engine has two separate thermostats. The
thermostats differ in type and opening
temperature. The smaller, single-acting thermostat
opens at 79°C and the other, double-acting type, at
83°C.
When the coolant temperature is below the
thermostat opening temperature, the coolant (A)
circulates through the by-pass hole into the coolant
pump. The smaller, single-acting thermostat (1)
opens first (at 79°C), letting one part of the coolant
(B) into the radiator. Following the load increase,
the other thermostat (2) also opens (at 83°C). This
is a double-acting type, which closes the by-pass
hole when it opens and directs the coolant (C) into
the radiator.
There are no separate winter-type thermostats.
