Temp gauge not working
Hello HT. Recently, I noticed that my temperature gauge in my Si cluster hasn't been working. I ordered a new Temp Coolant Temperature Sensor thinking that was the issue, but no luck. I noticed that there was some dark liquid (probably oil?) inside the temp gauge unit as well as the wire that connects to it. I don't think it's a fuse because my entire cluster wouldn't be working if a fuse was bad, right? Are there any other suggestions or thinks to look for? I'm going to use a good cluster later on today to see if the cluster is bad

Re: Temp gauge not working
I looked up one of those diagrams for the temp gauge and I used a jumper wire for the sending unit wire and grounded it to the block, the temp gauge rose all the way to "H" so the temp gauge is good.

Re: Temp gauge not working
Is the sending unit supposed to flush with the engine? I tried tightening it and it's pretty stiff already. The last thing I want to do is break it off from over-tightening.

If, after replacing the sending unit and bleeding the cooling system, the temp gauge stays on cold, then chillerice's idea about a stuck open thermostat may be correct.

Will do. I noticed that it takes about 5 to 10 minutes of driving for my temp gauge to "almost" go halfway. Maybe the sending unit is going bad. I'll find out if the thermostat is stuck open.

Re: Temp gauge not working
I found a quick test for a stuck open /partially open Thermostat.
Set the temperature to cold, and keep the heater fan off, and recirculate door closed (no outside air flow through).Drive for a few miles, and see if the temperature rises sooner than before. Change the heat lever to hot, and see if you get some heat.
