| Well, OK so this is not the 180deg. t-stat. It’s the OME 195deg t-stat. That one thing that’s makes the OEM different is the copper stem sticking out from the bottom (left). It’s made just for the 4.7L engine. Dodge doesn’t make an 180deg. t-stat for the 4.7L. The stem moves when the t-stat opens when reaching 195deg.s and blocks 50% of the by-pass hole in order to better control the temperature of the coolant. No aftermarket 180deg T-Stat is made to work in this configuration. The 180deg aftermarket one in my truck works OK. I wonder how more even and cooler a 180deg with the stem? |
