It would be hard for your engine to actually stay at 130 , even with no thermostat. I would think your guage is reading wrong. Does the engine feel very hot? 130 wouldnt feel very hot.

seems to be operating at a normal temp....not too hot or cold..i'v using the mustang gauges and i'm wondering if i've got a bad connection?....

Possble bad thermastat stuck open,but check the sender first. Use a known good thermometer imersed in the coolent and check to see if gauge reads the same.

Stock Radiator or BMFAM unit? If you've got the stock unit I can't imagine that even without a thermostat that you'd run @ 130. With a BMFAM unnit and cold temp's outside it's possible if your thermostat's stuck opend.
Get an infrared heat sensor and check it. Armed with that infor it then its a process of elimination.
Good luck.

Take the sender out and put it in a pot of just-boiled water. It should shoot right up to 200 or more, depending on how fast you are getting the water from your stove to the garage.
That's the easy part. Now you need to know what voltage output to expect from the sender at both ends of the scale. Once you have that you can use a voltmeter to determine if it is the gauge or the sender. Sorry I can't provide this info for you. Maybe someone else can chime in here.

It's not voltage, it's resistance. The system is always at 12 volts.
The sender is at high resistance when the temp is low. Resistance drops as the temp goes up.
There's a Ford Rotunda tool to check it, but, the senders are cheaper than the tool I'm sure.
Change the sender and see if that makes a difference. If it doesn't, you have a spare.
Are any of the other gauges acting like they might not be right?
Make sure ALL your grounds are attached and are GOOD. A bad ground will add it's own resistance to the system and that can cause the gauge to get a false signal.
Mick, I see where you're running the stock gauge. Are you running a stock sender? Are you sure the gauge and the sender are compatible with each other? Are you sure you're not using what had previously been the sensor for the computer?
Stock Mustangs have a sender for the gauge (up front near the distributor) AND a sensor for the computer (in one of the heater hard lines). They're not the same part.

We have basically the same motor. I run at 195F pretty much all the time. If I stop at a light for a bit, it will get up to 212F, then my fan kicks on. I've got a 180F thermostat in my car.
