Re: Wiring Diagram
Does your 86 have the electric fan, or the clutch fan? I don't remember when they actually started the electric fan setup.
If it is the electric fan and the fan is not coming on at all, you can jump the green wire from the relay to either a switch to make a manual fan on/off switch, or you can just take the wire coming from the sensor in the pass head and ground it out. When you do this, it will make the fan come on anytime the ignition is on. I f you're not into all that, you could also just turn your a/c on, and the fan should start up.
When is the car overheating, when you are driving, or just when stopped? Is the front lower air dam in place and in good condition? That piece directs air up into the radiator. If it is missing or broken-up good enough, then you will not cool very well while driving.
A bad/sticking thermostat, collapsing hose(s), dying water pump, clogged radiator/heater core, and/or bad radiator cap can all make a car overheat. Not to mention if the timing is off, it can overheat too.
As far as all the vacuum ports on the car, if you don't have to pass smog, then I would gut the stuff.
If you are dead set on keeping everything stock (why?), then I might be able to dig up my Chilton's manual and scan you a few pages, if it will help.
