Hello all, I recently pulled my 4ZE1 out of my 1988 Trooper II (manual transmission) and I sheared this off while hoisting the engine out. I can’t find any sort of diagram or schematic to tell me what it is. I’d venture to guess it’s some sort of vacuum driven coolant temp sensor but I’m not familiar enough with these engines to know. If anyone knows I’d greatly appreciate what the nomenclature is. In the picture is the device with the spring in it which sheared off and was connected to the thermostat housing and the intake manifold via vacuum line.
