Cooling system
Cooling system is an overview of the cooling system used in the Pontiac Fiero.
Because the Fiero has a mid-mounted engine and a front-mounted radiator, the cooling system uses long coolant pipes running underneath the car. Proper filling, bleeding, and inspection are important.
Overview
The Fiero cooling system includes the radiator, coolant pipes, hoses, thermostat housing, thermostat, water pump, radiator fan, fan switch or fan control circuit, coolant reservoir, and pressure caps.
Air trapped in the cooling system can cause overheating, unstable temperature readings, poor coolant circulation, or coolant overflow.

Coolant filling
The Fiero cooling system should be filled carefully because of the long distance between the engine and the radiator.
