I have run Robert Shaw T-states exclusively for about 10 years now, I used to always change the T-stat when ever I changed Fluids or hoses until about 15 years ago. That's when I got a succession of junk new T-stats from my local auto parts store.
My mothers car had no overheating issues, I changed the hoses coolant, and T-stat, she drove it about 10 miles from my house and it overheated. After geting back home I discovered the "new" T-stat would not open fully. Put the old one back in and she never had another issue with it. Had several customers cars do simalure things. Stopped using Stat and NAPA brand T-stats after that summer.
I am sure that other brand premiem or high flow stats would work also, I have just never used them.

Me too. Went through the same BS with the cheapo t-stats. Best $ you can spend. I also like how they have the coolant holes in the t-stat.

I drove my car to the show we have at a drive-in rest. on sunday. Guess what happened. The new cheapo T-sat stuck shut & by the time I got there it was at about 240* & it was percolating in the overflow. I let it cool down took it home pulled the T-stat out & it was still stuck shut. I went to the speed shop & bought a Robert Shaw stat today & I'm going to get a new upper hose just because, & I hope this will help. The cheapo one did work fine for about 1 week & stayed right about 165-170 when I took it out about 4 times during the past week & now I'm back. But with this new RS stat & new hose I hope it will work better. I'll see when I go out tomorrow with it. I pulled the fan off as the 19.5 inch fan should be here then too. Crossing my fingers for fix to work.
