well i can officially say that i now have done the 180* thermo mod, i debated on doing it for the longest time for the simple fact that i didnt want to drain the whole radiator. i then found out something from another thread that i had never thought of, i only had to syphon enough out so it didnt spill all over. i decided to do it for a couple of different reasons.
1. i didnt like how hot the car ran before, usually up towards the 220 mark
2. i have low oil pressure when idling, i was a victim of the UIM failure, so i hope this keeps up a little bit higher.
3. I hope that it will help prolong the life of the engine.
i know many have done this mod and this all seems redundant but im excited so i had to say something, by the way very easy to do, the only hard part was scraping the old gasket off and making sure it didnt fall in the engine
