I was redoing the hoses under the hood and I got a little "WhileI'matis"--I decided to flush and fill the rad,all new hoses anfd a new T-stat--Here's my question--I have two T-stats--1 is a 180 and 1 is a 195 degree--If I put in the 180 it reads very low on the guage and if I put in the 195 it reads almost to the top of the guage--Which is to be expected since they open at different temps--What,if any, is an advantage to running a 195 or 180?--Any danger here?--Does the 351c like to run better on one temp or the other?--TIA don
