quote Originally posted by flimbob: On the 86, there is a heater hose running around the shock tower( shown above ). 87/88's have the heater hose connected to the long coolant tube on the passenger side. Where would one hook up the heater hose located at the trunk side of the motor on an 88?

the pipe going out of the back of the engine is the heater supply line, the one that tees into the coolant tube is the return.

on my car (a 1985 SE) I'm setting it up to dump the heater return into the coolant tube like the later cars. here's what I did so far:

Cut the pipe off of the coolant tree



Welded up the hole



and on my car, I am making a new custom pipe to relocate the supply to near the timing cover. I'd bet that you could pick up a early car's rear heater tube cheap enough and install it on the rear bulkhead, and then use the stock 3400 tube the goes into the lower intake.



the tube is actually pretty well placed, I just didn't like it on my car.
