i figured as such. Thanks for the info though. A little reference is better than nothing i guess.
Flushing any part of the system whether it's oil, tranny, coolant, etc... always makes me nervous. I think the FSM just recommends a drain and fill. I would stick to the Mr. T service methods.
It recommends a flush.
Monday I drove from Boise to the SFO area...temps in the NV desert were in the 80's-90's when I drove though...
At 80mph on level highway, temp gage needle was halfway up (pointing at the little logo thingy), Torque via bluetooth to phone indicated 185.9 (it's a 185* stat). The hottest it got was through a few uphill's approaching Reno...192.1* on Torque, temp gage was up a minor graduation or two.
13 quarts is capacity if you have rear heat...you'll have a bit left over. As far as removing as much coolant as possible during draining, remove the elbow on the oil cooler just aft of the oil filter.

So I just had the flush done, I hit 208 on the way home from the dealership. That's pretty much the same as before the service I think... I was lazy and had a shop do my last oil change, I think they used 15w30, could that cause higher operating temps?
189* is the hottest I've seen mine go
I use Toyota Pink in my 2000. Don't think/know if it matters.

Just stumbled across this and thought I'd chime in....
1999 LX470 with 247k. New radiator/hoses/Ts/T hoses/coolant flush with new Toyota red....
Driving from Seattle to Bend, OR outside temps hit 99F and driving over mountain passes at 70mph it would occasionally hit 203 on torque pro app, as well as hit 203 idling in traffic.
I was worried about it but after reading this post maybe I shouldn't worry. For the majority of the 300 mile trip I was running at 195ish.
My new radiator didn't come with the foam either which probably helps a lot.

How is your radiator cap, thermostat, and fan clutch? Those can all contribute to running slightly warmer than normal.

New radiator cap as well. Fan clutch was replaced by prior owner within last 50k. Only thing I didn't replace was thermostat because I couldn't find it when I had the radiator done. I had the part just couldn't find it. It was also replaced at the dealer in the last 75k miles.
Do thermostats go bad that often? Or is it just something people do because it's easy?
I forget the service life on a thermostat, but they can fail. Do you know if they used a OEM or aftermarket? Personally, I have compared OEM versus aftermarket thermostats and the aftermarket units ran several degrees warmer than OEM. If you are unsure of the status of the thermostat, I'd pick up a OEM unit and install.

I have an OEM thermostat in my glovebox. I'll put it in when I get back home. But pretty sure all parts were OEM since they were done at the dealer. The only non-oem part is the radiator (koyorad) which I just installed a few weeks ago because the OEM radiator was leaking.
Well, I hope they used OEM, but I have read plenty of stories here about folks having work done at the dealer only to later find out they did not use OEM parts.
Also, I'd get some foam to install around the radiator to help seal it up.

You're probably right. And even if they used OEM I wouldn't put it past them to not install it correctly. There are some other things the dealership did that make me question if they know what they are doing half the time.
