i know 200 is not high...im trying to stabilize it. when i put this motor in and the 5.0 stang motor...i used a 195* both times. i wanted to see how bad things would get running the right tstat. well, with the mustang serp/fix fan...it was stable. switched to explorer serp and it stay at 200-then went to 205-210* on highway. so a couple weeks ago while trying the explorer radiator...i swapped in a 180*fail-safe stat. now like i said the temp holds 180-185* in any traffic jam at any temp outside(thats great!) but i dont like how i cant seem to control it going to 200* on the highway(once in a while at hi speeds...205*) once i come back to normal traffic...it takes a long time to come down to normal temps. also this motor was treated to a new explorer water pump. i sure the radiator needs a good flushing(not like i do...but i service place)
