I've searched for a while and can't seem to find anything.

I'm looking to put water temperature probes in two spots on my S4 - one in the thermostat housing coming out of the engine block, and one at the outlet from the radiator. I'd prefer to not have two gauges. A double needle gauge would be perfect - one needle for the block coolant, one for the radiator coolant.

Does anyone have an idea of where I could find this, or if it's even worth it? I'm working on building my car up for autocross/track/hard highway runs, so coolant temperature information is fairly important to me.

huh!

 

If you take a reading at the thermostat that is the hotest the coolant will be, if you are O'k there, you are O'k everywhere else. If you are wondering what the post radiator temp is, weld a bung on, and move your sensor temporarily. IMHO there is no reason to constantly monitor both. Carl

OR... you COULD get one gauge and install two sending units, make the grounds common and put a switch on the input leads to switch the gauge between either sending unit.

 

there's a good idea!!
