censor in cylinderhead.
on the passenger side cylinderhead, on my 91 there is some kind of censor. What is that, and if you could give my the gm par nr for that would be great. During my rebuild I lost this censor :o

The sensor in the right-hand head provides input to the ECM and results in fan cycling and dash readouts.
I have found that for GM parts, The Last Detail (1-888-527-8338) near Atlanta GA. deals with GM and AC/Delco almost exclusively. Their part number (not GM's number) for this sensor is 677731 and their last listed price was $13.00.
Hope this helps.

The right hand sender is for your dash gage. ECM gets it's signal from the engine coolant temp sensor below the throttle body. You can get replacements at NAPA for either. Just be clear as to what you want. Gage is a single blade sender that decreases in resistance as it heats up. Most have a single green wire. Ground that wire against the block and the readout will be about 300 degrees. Coolant Temp Sensor is a 2 blade thermistor with a 5 volt reference signal from the ECM. It too decreases in resistance as it heats up simply meaning that the ECM sees a higher return voltage with higher coolant temps. It's leads are usually yellow (reference) and brown (return). If there's an open or short in this sensor, you'll get a trouble code.

*IF* it's the same part on a 91 L98 as on an LT1 then the part number is 25037332, price = $22.20 list, $12.77 net at Superior Chevrolet. I just replaced one on my engine.
