ps2cho...I got my car back yesterday from the shop with the new engine installed and it is running midway between the 80 and next dash mark in 75 degree weather! Has the Zerex in it and runs good but when I sat at the carwash waiting to go through, it started climbing over the dash mark (100 degrees) until I got through it, put it into drive and pulled forward. My previous engine ran a little above the 80 mark and when hot, right under or at the next has mark. What the heck??? I'm scared to death to overheat this thing again!
