I need to know where the temperature thermistor is 5.7 iroc 87'

 

A little more information about your setup would be helpful. Thermistor does not exist. If you are talking about a thermostat, then that is located near the front of the engine on the intake manifold, underneath the water neck.



Hope that helps

The tempaure sensor is that little black plug on the left side of the red circle in the prior post.

It is on the passenger side on the front of the intake manifold if looking at the motor while the hood is open
