Overheat after exhaust install?
So I took in the SHO to have the Midwest Y-Pipe installed, as well as the Dynomax catback. I had them put in two new O2 sensors while they were replacing everything else. It sounds great- problem is, when I got home, the overflow bottle was pouring coolant out the hose, and onto the ground. Looks to me like 3-4 cups came out, not counting what may have come out while in transit. It never really overheated, stayed in the mid-normal range, but the fan was on, and I did notice it to be odd since it is nice today, about 65 degrees, and the fan was coming on just as I would pull up to lights- before I would sit and idle for a long time.
Anyone have anything similar? Anyone have a thought as to why? Is it something to do with the exhaust, or is it to do with incredible timing, which any SHO seems to have in volumes?
