Default Where Does Your Temp Gauge Sit?

I'm wondering where everyone else's temp gauge sits when the engine has been warmed up. I have a 1993 2.4L that always sits low. The truck has never gotten anywhere near half gauge. I'm attaching a pic of the gauge after the truck has been run to temp.

My first question is:

What is the outside temperature your driving in?

Ideally, the needle should be at about the “46%” line, if you think about the halfway line in the temperature range, think of that as the “50%” line. The thermostat temperature range, I believe, should open at 170°. My needle generally stays at 46% in summer temps and the needle stays much lower in winter at around the 40% range.

The link shows a photo my temp gauge needle during the hot summer of 2021 with 95* outside temps and the A/C running.

Does the heater work good in the wintertime? If you have AC, does the AC blow ice cold in the summer?

If the answers are yes...then count your blessings and call yourself lucky. Just means your engine is getting superior cooling.

If the heater blows sort-of warm, then look to changing out your thermostat for a genuine OEM Nissan thermo.
Whatever it is...you are better off being a bit low than overheating. That is always bad. It is also possible that someone removed the thermostat and never replaced it. When this is the case, you have a 'free flowing' cooling system. Takes twenty miles before the heater really works.

When you use an aftermarket thermostat in these trucks, half the damn time there are problems. Either they stick shut and the motor overheats, or they never close and your gauge stays low and the heater barely works. I would pull the thermo and replace it with OEM.

What brands of T-stats are giving trouble? I've never had a problem with a Stant replacement, but I think they are a major OE manufacturer. Now in their third century.

I have a 95 with the V6. My thermostat is new/OEM and my gauge reads about the same as yours. I thinks it's either the gauge or the sending unit, I don't think it's your thermostat.

Mine is the same as theirs. Usually rides just a tad above the cold setting.

The AC doesn’t work but the vents blow hot in the winter once the truck has warmed up. It does take awhile to warm up.

Same year and motor. Mine sits a cm before the half and a littler less if I'm moving.
The only time it went to half is when I was offroading uphill a little, but to be honest I think it's because I didn't bleed the coolant well enough. Some air came out of the bleeder screw.

My dad's D21, a 97, also sits before the half.

Also, there are different types of clutch fans out there too that blow harder than others.

That's where all of my KAs have sat. My VG too before I put a 180º in. For stuff like sensors you can always try the stealership parts counter, Nissan Parts Deal, or Coulter Parts Center. They have access to more than you'd think and the prices really could be worse.
