Coolant Temp Sensor Pigtail ID - Pirate4x4.Com : 4x4 and Off-Road Forum

First off it's a 95 Chevy K1500 TBI 350 that was rebuilt by the previous owner. I went to buy a coolant temp sensor and all of the parts stores have sensors that are 2 wire pigtails.

The one on my truck is a one wire and looks like this:

The one all the parts stores have looks like this:

I'd just swap the pigtail but it's one wire vs two. Anyone know what year Chevys had a pigtail like that?

The one wire connector goes to the drivers side head for the temp sender for the dash gauge.

The two wire is the temp sensor in the intake manifold next to the thermostat for the ECM.

The one wire sensor in your picture is for the gauge, and there should be a two wire sensor for the computer in the intake manifold next to the t-stat housing.

lumpdog beat me to it.

The Standard number for the sender (ask for a "switch") is TS-253. I don't remember the pigtail number off the top of my head, but I'm pretty sure it's an S-xxx number, not something easy like TX-3A (the pigtail for the TX-3 temp sensor everyone is trying to sell you).

Hopefully having the right sensor in hand will get the parts guys closer to getting you the pigtail...I know we have them on the shelf at work and sometimes that's the easiest way to find them.

Thanks, I ended up replacing both of them because they were both so brittle that the plastic just crumbled. Therefore I didn't have anything to bring in plus parts guys are dumb asses. I saw the one on the side of the head but didn't see the one at the front of the intake. I'm retarded too i guess.

Thanks.

I'll look for you tomorrow and come up with the Standard number for the pigtail on the gauge sensor in the head if you don't come up with one by then.

Look at the PT728, it looks like about the most similar.
