i have a quick question about my autometer water temp gauge, as soon as i turn on my car the temperature rises up even before the stock gauge reads that the car is fully warmed up. is my gauge working properly or is it the sender thats not working?

oh and one more question i saw that my alternator belt was loose so i tighten it up t when i turned on the car i heard a popping noise i immediately turned off the car and loosen the belt then turned it back on with no problems what was the noise?

 

the stock gauge is slow to read. Normal temps run 180 to 220 once warmed up.
Pop? belt not sitting properly in the pully before you cranked? maybe...

 

I have an autometer pro-comp ultra-lite water temp gauge, if my engine is cold, it doesn't move when I turn on the car.

How/where is your water temperature sender installed?

 

is your sender unit grounded?

 

my sender in in the thermo housing and it is grounded by the sender. should i change the grounding location?

 

its grounded by the housing, so thats not the problem.

 

The stock gauge should read fully warm (or very close to) before your aftermarket gauge shows any change at all.

If your aftermarket gauge starts to show a temperature change before your stock gauge reads fully warm then your thermostat is either missing or it's faulty.

 

using the throttle body coolant line mine will read about 120deg before the stock one moves off the bottom.

 

I have mine mounted to throttle body coolant line too. my aftermarket gauge also reads much faster then stock one. i guess its normal. during normal driving, temperature never goes above 212. even when standing still.

 

the temp on my gauge starts rising to about 150 in a minute! and it just keeps on getting higher and higher. my temp gauge never worked that fast before

 

thats weird. when starting the car cold, open the filler cap and check for bubles . if you have bubles at cold startup, your coolant seal is done. if you dont get bubles, try burping the system

 

thanks im going to try it today. i hope is not a coolant seal
