H20 GAUGE
 

WHERE IS THE BEST PLACE TO PUT THE SENDING UNIT FOR A MECH.WATER TEMP.GAUGE

There are a few locations. I usually use the intake manifold location ( I have Team G, towards the front) on my mechanical guage. Having said this, I am not sure if it makes a difference if sensor is located somwhere else.

i always put them in the head beacuse your heat is in the heads and you will see your temp sooner and after you shut your motor off you will see your head temp,, good luck
