Check the sending unit between the left first 2 spark plugs. Ground the wire with key on (gauge should peg full hot). If it does change the sending unit.
Bad temperature sending unit? Bad gauge?
Buy a new Speedometer cluster. The external Temp gauge is extremely rare
195 to 210 is normal
Waht is the answer?
usually on the left of the engine between the first two spark plugs
seriously? it tells you what temperature you engine coolant/antifreeze is. that is how your gauge on the dash knows what your temperature is at.
In my experience with my Chevy it was a ground wire
because the engine in that car does not cool down
Change the thermostat it's sticking and throwing the engine temp sencer to kick in
NO. it has NOTHING to do with the engine starting. It works the fuel gauge in the dash only.
220 is not excessive
were is the fuse for speed gauge
