Question about Cars & Trucks
Issue? 140 is low, could be problem if you need heat. but otherwise? Mileage may suffer if temp is too low. Sounds like the engine thermostat is missing or not functioning properly.

as long as it stays in the the nomal area ,its ok . just means @ an idle the pressure is lower . is normal for it to go up and down . if your oil pressure gets to low the check gauge, or engine light will come on .

The fans come on only when hot or the AC is on. There are many fuses that have to be good for it to work. The fan relay should have 2 pins hot with the key on, The other 2 should be ground. with the key off one should be hot and the other can then be ground the other pins that are ground one of them is the fan. the other becomes ground when the computer turns the fans on. If you don't have a pin thats hot at the relay all the time then theres a blown fuse or even the power wire from the battery at the battery

Temperature sensor is in intake manifold.
Water is not flowing smoothly through the manifold.
2 immediate things to try........
1. Replace the thermostate (about 6 dollars). If you drive the car to an Autozone for the thermostate purchase, they will show you where it is located and how to replace it.
2. Flush (thoroughly) the cooling system. No shortcuts here, buy the flush and follow directions. Have the heater turned on HI.
After the flush, fill with 50-50 antifreeze-water.
Problem within engine are done. Other issue MAY be the sending unit (as your Autozone guy about that... it looks like a spark plug and takes about 3 minutes to replace.
