I just picked up this '88 Sentra 4-speed at auction for $375. It runs and drives fine, but runs on the hot side. Doesn't seem to overheat, but it might if I let it idle too long.
136,000 miles.
Runs hot (according to gauge)
Cooling fans do not kick on
Coolant is obviously old and dirty (nasty brown color)
Poor heat from heater.

I am planning on flushing the coolant on Tuesday, since it's such a simple procedure on this car. I don't have access to AllData right now, anyone know where the thermostat is on these?

 

Just follow the upper radiator hose and you'll locate the thermostat.

Cool car! I have the same one, and even the same issue. Eventually, I realized it was low on coolant. A friend of mine figured that one out for me. I know, I probably should have figured that one out on my own,m but I really don't know much about how cars work, just know how to drive them.
