Would a NA thermostat housing work correctly with a TII water pump? And how do you tell them apart? When replacing the water pump I was kinda curious just in case (I wish previous owners would do it right .)

 

They're basically they same. Turbos and auto NA's had a temp switch for the auxiliary e-fan in them, but the manual NA's (which didn't have the fan) didn't have the switch. One should get one to match what you have.

 

Kk Thanks.
