Ambient was 73F. Mild grade I drive all the time with no issue, 800-1100 feet over about 4 miles. Turned the heater (including rear) on full-blast, high vents when I hit 204. Air coming out of vents was NOT HOT. I'm baffled by this. After a few minutes, the vent air became hot--too hot to keep my fingers in front of--and the temp dropped 37 degrees in two minutes of more or less level travel.
Parked it, came back 20 minutes later and it was 186 (right where I like it.) Start home and it's back up to 216 in two minutes. Took a steeper downgrade home, foot off the gas for much of it, wound up back at 186 when I reached the driveway.
W.T.F.?
Coolant, oil, tranny fluid levels fine. Radiator does have a slowish leak, but that's been true for a year. Hoses replaced a few years back. Checked coolant prior to trip. Will check fan clutch tomorrow.* Only recent work front brake pad swap.
Could be unrelated, but the day before I noticed a shaky idle on startup, with rpms down around 400. Dunno what that was, but didn't feel right. I'm thinking to check out Joey's famous overheating thread.
In the meantime--any ideas?
* I'm told the process is, have someone kill the engine--and grab the fan a half-second later. If you can stop it, the clutch is gone. Sounds like a finger-breaker to me, but I'm told it's not. Is this the correct procedure?
