Many thanks for the response, but I must beg to differ.
At first, I did exactly what you described and guess what - NO stat! My initial thought was that the previous owner removed it in a lame attempt to cure a cooling/heating issue. No problem, right?
Upon closer inspection I found the curious words "thermostat at water pump" stamped into the fixture attached to the upper hose that I had already unbolted from the block. I then traced the lower hose back under the exhaust manifold to what I assume is the belt-driven water pump.
The thing is, in addition to being difficult to get at (thanks Chevy!), There are two separate fixtures between the lower hose and the water pump.
Which one is the thermostat in, or do I have to remove both of them to complete the repair?
