Aptiv (Delphi) connector for Coolant Temperature Sensor Is this the right connector to plug in to the GM 2134333 Coolant Temperature Sensor?
Our coolant temp sensor cracked, and the harness connector and the part of the sensor that it latches to fell down on the header pipe and melted. Needless to say it isn't running good this way. I've got a new genuine GM sensor on the way. I'd rather just trim the ends of the wires and install a new connector, rather than splicing on a new "pigtail." I have all the correct crimp tools, and I'm pretty sure I even have some of the Delphi/Aptiv 150.2 "pull to seat" terminals already. I really just need the mating connector piece for the sensor. That one looks right to me, but I was hoping for confirmation.
If it matters, this is a LM7 engine, factory heads, from a 2001 pickup truck or suburban. The same sensor was used on a lot of Gen III, Gen IV, and even Gen V engines from the late 1990s up through 2020 at least.

I don't know about the original Metri-Pack 150.2 pull-to-seat connector but you can service replace with GT150 Mini style connector, terminals, and seals. This is the same way many new harnesses are made these days (the MP 150.2 fell out of favor a while ago).

The crimp on the GT150 is just a little smaller than a comparable Metri-Pack. Don't be surprised if you have to crimp once, and then move to the next smaller crimp jaw and give it a little extra love tap to finish the crimp.

I'm pretty sure that metri-pack 150.2 connector is correct for the OEM connector. I did similar research when I was about to replace mine and landed at the same style number. I didn't end up getting it since I discovered I just had to bend one of the internal prongs down to make better constant contact with the male end at the temp sensor and that fixed my temp sensor issue.
Yes, that is correct, but the GT150 Mini is preferred replacement and will plug right in to the sensor. The link I provided below has part numbers for shrouded (hooded) and un-shrouded versions, and all the related bits and bobbles needed to complete it.
