Great, now I'm worried it wasn't just an oversight at MAP and seems somewhat prevalent amongst other owners. I'll watch it and hopefully it won't drop again. At least it won't be a hard issue to fix.
Just checked my coolant level, and it was slightly below minimum. I’ve had my bronco for about 8 weeks.
I didn’t check my level before going off-road last week, and engine temps were higher than usual. Temps while driving on road have varied between 195 and 210, but off road temps climbed from 217 to 221. Seemed a little higher than expected, as it was only in the 60s. Perhaps being a little below minimum coolant level caused the increase temp. Has anyone noticed a range of normal engine temps?
Ok, one weird observation to share. I turned on the heater and than didn’t seem to drop the temp. I ran it for about 30 mins and the engine temp didn’t seem to budge. I switched the ac on, the temp dropped 10 degrees almost instantly. My experience has been just the opposite with previous vehicle.
