Hi I'm new to the Blazer Forum. I'm looking for the location of the temp sending unit on my 2.8 V-6

 

there are 2. One reports to the ecm and it will be located on the top of i take very close to your top radiator hose. It's very easy to locate. The other is for the temp gage and it runs into the side of the block. Not 100% which side. Hope it helps.

 

Thanks for the reply, I think you may have helped me. the problem is the gauge does not respond.

 

that one should be on the block. Good luck.
