No. There's a difference between 2.5 and v6 pipes and then there's a change in design for the 88. As well the v6 has three pipes, the 2.5 has two.

The 88 pipes curve into the center of the car at the front end and bolt under the front subframe, the earlier pipes curve behind the wheel areas to the radiator.

Also if you throw the cross over pipe in there, they are different if manual or an automatic.

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.
