Something kinda funny is going on, so here'* the story.

The Bonneville was acting normal up until about 1.5 weeks ago. Normal, as in the temperature guage, on the highway, was about 1.7-2 ticks below half. Woke up one morning, drove to work, no problems. Had to go out on a service call, the guage was sitting half tick below half the entire trip.

I figured, alright, t-stat is probably just sticking, so I changed it out, bled the system, same thing.

Skip ahead 1 week (I was out of town on business so my car just sat at the airport), and in the midst of trying to figure out my crappy current mpg, I noticed that my scanware was showing my current temperature to be 176*F, full operating temperature, cruising along at 60 mph. However, the guage was showing 1 tick below half.

So, now I'm wondering if there is still an issue, or even if there was even an issue, and my cluster is finally starting to fail on me a bit.

Anyways, no air in the system. Upper and Lower intake seal is fine. Not loosing coolant. However, I do have a mechanic buddy that is going to do a system pressure check on it Saturday morning for me (which means I get to drive the TGP around for a few days).

Oh, and the temperature guage seems to be more "fluttery" than usual. Meaning, the guage would climb normally, and only move if i'm going in slow traffic, or after I've been on the highway for a while, it would sit right at on spot. Now, it seems to move almost as soon as I speed up or slow down on the highways.

The temperature never gets to be too high to kick on the fans (although they are working properly) or cause any damage, however, it'* not what I consider to be "normal" for my vehicle.

Thanks,

Chris

the Temp gauge is innacurate. its for a reference at best.

No it is not that exact but it gives you an idea of where the car is running hot or cold.

So it'* a circa or thereabouts reading I take it? One more reason for a realtime scanning indash computer for autos.
