im having trouble figuring out exactly which senor are on the front of my 87 camaro 305's intake manifold one has a 2 wire harness connected to it its on the right side of my thermostat housing the other on is on the front pasenger side of my manifold the top is broken off it looks like there was a metal prong going into the top of it ive found the prong and ive serched the forumns and ive serched the internet im going to try to include a pic of the sensors im referring to


if u look at the pic its the one on the driver side of my thermostat housing and if u look on the passenger side of the front portion of my intake behind the hoses u can make out whats left of the sensor its blue in color
thanks for the help and if this jacks someones thread i appologize im new here
the pic is sideways its the top sensor and then the lower one thats blue

 

Coolant temp for the temp gauge
Or fan activation
My best guess

 

The two-wire sensor on the waterneck is for the Coolant Temperature Sensor for the ECM. The guage sensor is separate and installed on the left cylinder head.

An 87 LG4 should not have a sensor installed on the intake manifold.
