What is the small hose that connects to the Fiero thermostat housing. What does it do? Is that the Fiero Heater core return?
For the 2.8 V-6......
There are four hoses that attach to the thermostat housing......
Large coolant discharge to radiator
medium coolant discharge to heater core
two small hoses for the throttle body coolant lines, one off of the thermostat housing, the other off of the heater core feed line.
The heater core return is either on the passenger side undercar coolant tube (87-88) or the pipe nipple on the waterpump housing (85-86).
