Glad that was all it was

Garner, what exactly are they saying to do? You shouldn't need to drill a hole in the tstat. The 4.7L tstat has a hole w/ a check valve type thing built in to it, but the hemi doesn't use that design. You can drill a hole in the tstat, but this effects how it operates as there will always be some coolant flow. Whether it's good or bad is up to you. I wouldn't do it on my new ram, but I did do it on my old s10 as I wanted a cooler tstat but the 180 tstat in that truck ran too cold so I drilled 3 small 1/8" holes in the stock 195 tstat to allow the tsat to bleed. This was my solution to achieve a operating temp somewhere between stock and the 180.
