Engine runs pretty cold
I got the same thing, ive replaced both sensors, 180 thermostat and new water pump, and it still just comes up a little and stays, which is fine, my thermostat is opening at 180 and everything stays cool, even in 100 degree summer driving. im cool with that!
I had the same problem with my 96 v8 It swould overheat going down the ocean so I replaced the t-stat and now the heat barley works and the needle don't really move either found out that my overhearing issue is the fan clutch this summer I'm gjnna revamp the entire cooling system
