Isspro gauge issue?
My isspro EV2 preformax coolant temp gauge has been acting up, its sporadic, sometimes it works properly,sometimes it bounces between 150-230..almost acting like air in the system at times..Is the gauge/sending unit going bad?IF so which one??
I have lost a little coolant appx 1/4 gallon,I believe it was leaking from the small hose on the top of the radiator that goes to the right side of the reservoir, I guess the other question I have is, would the gauge act like this if cooling system is losing pressure/leaking??I wouldn't think so but it doesn't hurt to ask...

Check to make sure you have good contact at the connector at the back of the gauge, make sure the wires are completely seated in there. Also check the connector at the sender and make sure it is fully seated in the clip. I would pull the connector at the sensor and get some dielelectric grease in it.
Where is your sensor located? Water pump?

If you go to the ISSPRO website, then click "Support", then "Instructions", then scroll down to the bottom of the page you will see a file for EV2 troubleshooting. Definitely check the connection down at the sensor as mentioned above.

It aids in sealing the connector from water/contamination intrusion, it keeps the contacts from corroding, it's non-conductive, and it can help keep connector seals from drying out prematurely.

What's dielectric grease going to do that will resolve this problem?

While some of you run around with all kinds of electrical issues, I have not had one issue in 1,500,000 miles of driving.
With a bad or intermittent ground, the gauge will jump to max reading. If this is happening over and over it will give the appearance of the gauge jumping around.

Water is the enemy of any electrical connection, dielectric grease is added to each and every connection I ever make on my truck...

If the connection is corroded, it needs cleaned, and if that resolves the issue, by all means put some grease on.
