Want this question answered?
The 1999 Cadillac normal coolant temperature gauge reading should be 180 degrees. A 195 degrees thermostat could be used, causing the temperature gauge to read 195.
get a new sending unit i had the same problem
In most cases the fuel gauge sending unit in the fuel tank has failed.
ONLY if it matches the correct resistance in your pellet in the key. There are 15 different values of resistance the key CAN have. When a BCM is first put in the Corvette it will read this key resistance value. SOOOOO- the BCM is forever embedded with this key value and can NOT be changed (maybe if it rebuilt by a place like Cardone- but I dont know about this and have never read this in any corvette forums). So theoretically 1 out of every 15 BCMs can be put in any corvette assuming that all corvettes have a random distribution of key pellet resistance values. Just another way of saying you have a 1 in 15 chance of success putting a BCM in another Corvette
Hey Mischelle==It is great sat this temp. If you want you can have a manual gauge installed temp to see if the electrical gauge is correct. The vibration is the rotors or possible the rear drums. Either one can be turned to get rid of it. GoodluckJoe

It is necessary to read the density and the quality of the gauge. You should see the lower side.
sounds like your temperature sensor unit if you have already checked the thermostat and the radiator and fans are ok

Around 80 psi cold at startup, and 40 psi at normal operating temperature.
broken fuel gauage sensor or possibly a broken fuel pump indicator
25 gauge is the size of the needle not the syringe. they are measured in cc's
