Perfect!
Perfect fit! Always AC Delco whenever you can on your GM. The quality is great, it functions like it should, it was very easy to replace, it controls the temperature better now.

Mine came with seal.
This is what I got. It's not really AC Delco. It seems to be a GM part. I know AC Delco supplies parts to GM, but I don't know what the deal is with how this thing's packaged. It came with the seal and that's good because picture shows that it comes with a seal and the text says it comes with the seal. It is also stamped made in the USA. All good things. That's why I've given it five stars. I have questions, however, as to whether it's going to fit because the listing says it is 58.7 mm and it is stamped 54 mm. If it doesn't fit I will come back and certainly revise my review. Purchased for a 92 k2500 5.0 l.Edit:. It fit my truck just fine.

Exactly what I needed to repair an overheating 1995 Chevrolet C1500 truck
The thermostat arrived much earlier than expected and allowed me to get my truck back on the road a few days sooner. Even an easy installation can be difficult if you don't have proper tools and replacement parts. The thermostat I received was a perfect fit which made installation extremely easy. If you are experiencing a similar problem on a similar vehicle, I highly recommend ordering this thermostat.

O ring included
The product arrived with an o ring installed on the thermostat in the box. I was thinking I had a bad temp sending unit for the gauge but the problem was the old motorad thermostat that was opening prematurely. The engine was never reaching an operating temp of 195 which helps explain the poor fuel economy lately. Even if I have to replace the AC Delco every few years I think it is a better part than the motorad. I would recommend AC Delco for the thermostat.

careful about fit
the thermostat appears to be well made, however it DOES NOT fit the 95 K2500 diesel suburban as promised. the thermostat is literally too small and falls into the installation site.
