Water temp gauge problem

[SBNova]

I just got a 93 Ty, and Ive got a few issues to figure out. My water temp gauge never gets above approx. 130 degrees. It is at the bottom of the scale when cold, so I know it moves with a temp increase. Is the gauge fed directly from the coolant sensor? On older vehicles you could ground the lead going to the sensor and the gauge would read max value. I am basically loking for a way to diagnose if this is the gauge, sensor, or something else.

I have read about loose needles on oil press. gauges- and mine seems to work fine. Just this water temp gauge.

I am also wondering about the intercooler pump. I believe its wired as factory (truck is supposed to be stock)- when is it supposed to turn on, and how do I verify that it works? I know, look at the coolant for circulation- but Ive heard that they dont run all the time, so how do I make it run to check its operation?

That is normal for most of these trucks, the stock gauge is not very accurate. If you have datamaster check the temp with that. But where yoiur gauge is is normal.

Just get some aftermarket gauges for water temp, oil psi & boost, the stock ones suck and are hard to read:2cents:

Yeah I plan to scan it. Ive got tunerpro that I use on my vette, I just need to beak it out and hook it up. We have the '7749 ECM's in the Ty's right??

Mine does the same thing. I just ended up getting the water temp gauge on the pod (which I still need to hook up by the way). Do a search for a thread on the ic pump and how to hotwire it to make it run all the time. A lot of guys do this. Also, you may just want to replace it with the higher flow pump. I just ditched the whole system and went air to air.

I scanned the Ty for a very short period today. My temps are great, despite that factory gauge reading. I could not get the dash of tunerpro to show knock counts or knock retard, it would only show in a data column that was hard to read while driving. I didnt datalog, I was just casual driving through the neighborhood watching (and feeling) for TCC lockup, looking for closed loop, checking BLM's and trying to check for knock under light loads.

I got alot of knock. One light load acceleration I saw 300+ knock counts on a short 10mph acceleration from 30mph.. I guess I need to do some tune up type stuff, verify timing, and start at the beginning.

Im sure I'll have lots of questions soon.....
