Are Fiero coolant pipes the same for all models?
Does your username mean you have an '88?
I'm pretty sure the large coolant pipes are the same for 4 cyl or V6.
However, in '84-'86, the heater pipes had an independent circuit, with both ends connected to the engine. For '87 & '88, the heater return T'd into the right coolant pipe instead of returning to the engine.
So the '87 & '88 coolant pipes have the heater return connection near the rear of the right-side pipe.
Also, as noted, the '88 pipes are different than '84-'87 pipes where they route around the front suspension.
And because the coolant connections are all at the pulley end of the engine, there's a crossover pipe bolted to the engine connected to the left coolant pipe by a hose.
