what is up with all the overheating problems out there? heres my story. car ran great, the autometer was never past 180*. car went in the shop and now she runs at 210* or so all the time. when i sit at idle, she goes down to 190 or so. then on the street she goes right back up. never overheating, but i think that running at 210 only gives you 40 degrees till the danger zone. and thats not a lot of wiggle room. she has new t/stat. 180* (was thinking of putting in a 160*) before she went in the shop i put in new w/pump...rad...and hoses. cant quite figure it out. any ideas? thanks ed
