Where is the thermostat located

Ok thanks a lot!

Oops.....missed that it was a 5.3! I'll go sit in the corner now.....

Sure.... lower passenger side of the water pump..You need to know if the pump has been changed, different t-stat! . . .LOL...cb30..... don't forget the dunce hat!..... I answered wrong at first myself... then changed it! You are right though on most GM'S..... As we know them!

Thanks everyone for your help.

WE glad to help!

I didn't help , but the entertainment factor was there , so , also thanks everyone!!!.........AND I learned something too( I think...).....

I am still wearing the dunce hat in the corner till someone says I can take it off........but I have a couple of cold beers here too so, I'll be okay for awhile!! LOL!
