Could be,
sticky thermostat
or
low coolant level.
It is for the Temperature gauge, it feels more balanced than being either side of the middle
no more than 3/4 of the way
It might be. If you put in a barbell that is a smaller gauge than your piercing, then it is a possiblity (depending on how old the piercing is) that it may shrink down to the size of the gauge you have in it.
Your gauge could be bad but more than likely it is the temperature sending unit. It is a fairly inexpensive thing to fix.
22 gauge is thicker than 18 gauge if you live in an upside down and backwards universe. But since we don't, 18 gauge is quite a bit heavier than 22 gauge.
Temperature gauge may drop when heater turned on because additional coolant from heater core is introduced to cooling system - usually this coolant is cooler than what is currently circulating
No. The common, plain old, earring size is almost always 22 Gauge. 16 Gauge is just a bit smaller than the common piercing size of 14 Gauge. The size chart goes down in increments of two from 22 usually down into the negatives of 00 gauge, and then breaks down into diameters.
1988 bronco gas gauge works when full than goes down faster than normal
Because Science.
More than likely the gauge is NOT the problem.Just make a jumper wire and disconnect the sending unit wire from the water temperature sender and place one end in the connector and ground it to the block and the gauge should work or show say hot.If it does show the gauge show the needle in the hot it is the sender is faulty and should be replaced.If the gauge does show the needle move to hot and moves to the cold it will be the gauge is bad(not likely in most cases).Have a helper in the truck to turn the key to the ON position not running when you ground the sending wiring to the block to note wether it moves up to hot or down to cold when you do this to simplify the issue.I will bet the sending unit for the water temperature is just worn out most of the time.
Check the temperature sensor.
Your gauge could very well be bad, many pools that we took care of the gauge on the filter was bad, after backwashing the filter just check any of you lines going back to the pool and your should notice the pressure is a lot higher. A lot of people just check the flow by placing there hand at an outlet to check pressure than by walking over too the filter and reading the pressure, instead of buying a new pressure gauge.
