I may simply need to gather more data, but mine seems to be around 230, plus or minus a couple degrees (measured via bluetooth obdII) after an hour long ride. Is this "coolant temp" in the torque app using the cylinder head temp sensor, or something else?
Anyway, it seems on the hot side from what's been described here. Not sure what it could be. It was a 90 degree humid day and the intake temp was well over 100, but this shouldn't matter. The fan did come on high for about a minute, but it was with the A/C on, and after running wot through first gear and then pulling into my office, essentially stopping (making space behind me so I don't get rear ended during the sharp turn). All other times wth a/c on, the fan is audible, but you have to listen closely to hear it. The fan is either off completely or on very slow in more mild conditions. I've air bled properly, and pressure tested to 15 psi with no drop over 30 minutes.
I only checked the temp because of the fan screaming. There was no other indication of anything wrong, and I wouldn't necessarily say the fan screaming was a bad thing or indicative of something wrong. The needle on the dash was exactly in the middle, maybe its ever so slightly lower than middle under more normal conditions?
I checked the wife's 06 Taurus for comparison and it got to a max of 220 on a much drier and cooler day, without A/C running. On average it was 200 to 210. 230 in the LS seems slightly hot, but also plausible. I have fairly high miles so maybe the water pump can't move the coolant as good as it used to, or extra stubborn air pocket stuck somewhere. Just guesses though. I have a ford degas tank waiting to go in when the current hasty dorman repair gives up, as well as a new aux pump and dccv. Sorry for the long stream of conscience.
