ICEWOLF 53 Posted December 3, 2017 Hey guys Was wondering where the best location for my Holley sniper EFI temp sensor would be? Holley instructions say: "Must be installed in a coolant passage in either the intake manifold or cylinder head. Do not install in thermostat housing." I presume that means neither of the 2 previous temp sensor locations will do? One was factory just below the thermostat housing and the other was a speco gauge in the water pump just below the heater hose Share this post Link to post Share on other sites
Crazy2287 1,886 Posted December 3, 2017 Any coolant passage on the engine side of the thermostat will be fine. Cold side of the termostat is no good, as it wont show engine temp until after the car has already reached operating temp (Thermostat opens at 80+ degrees C.) The same place the heater hose comes from is a good option. Share this post Link to post Share on other sites
