Question Help Identifying a Sensor

Hi there, I have an '87 S10 2.8 v6, and am struggling to identify a sensor/sending unit that has deteriorated. Any help would be greatly appreciated.

Re: Help Identifying a Sensor

That should be your coolant temp sensor for your temperature guage.

1992 S10 Extended Cab, 2.8, 5 speed - paid $50 for it 11 years ago - still running strong (as strong as a 2.8 can)

Re: Help Identifying a Sensor

I thought that was the sensor next to the water neck on the intake. I just replaced that one.

Re: Help Identifying a Sensor

K so are they both identical sensors and one is temperature for the ecm and one is for the temperature gauge?

Re: Help Identifying a Sensor

My Haynes manual refers to the thermostat location as the "engine coolant temperature sensor" and the cyclinder head location "coolant temperature sensor". Theres only a coolant temperature sensor available online so I'm assuming they're the same piece in both locations?

Re: Help Identifying a Sensor

No, not the same part. That should be blatantly obvious, just by looking at them.

Re: Help Identifying a Sensor

The connectors are different. You could probably cut and splice the new connect on and use the same style for both.

Re: Help Identifying a Sensor

Yeah you're right, the connector tops are just different. The one on the intake seems to be called coolant temperature sensor, and the one on the head a coolant temperature sender. Rockauto has both. Mystery solved thanks guys.

Re: Help Identifying a Sensor

RAVEN is correct - they are NOT the same...not just the connection is different but internally the way the pass/alter the signal is different

Pay close attention...one is WITH GAUGE and one is WITHOUT (light)
