Did you solve this? I am battling the same deamon now. My gauge runs at 95, then spikes to 105ish, erratic, then settles back down to 95. I bought an IR temp gun and have taken reading many., many times. (done all the usual, fluch, clean, replace t-stat-80 degree)

Nowhere on the block, radiator, hoses can I get a reading of more than 75...so, I know my cooling system is working just fine. So, I had to focus on the sending unit to the guage portion.


I replaced the sending unit, no change. All that is left is the Potentiometer and the gauge (ground or connection or broken gauge). These are more diffiucult as this requires removing the dash cluster, I have NO idea how to do this.

If you have made progress, can you let me know.
