Well, got in the truck today and noticed right away that the temp gauge was AGAIN in the red. This after I paid for replacing the thermostat and a coolant change, to correct this very problem!
The shop will have to fix it, but I don't want to spend any more money there... After searching around TW and elsewhere I think maybe the problem is the ECT sensor... Has anyone else dealt with a similar problem?

Bumping for this phenomenon.

The temp on my SGII has ready 186-190 for the last couple of years. This weekend I did a timing belt / water pump / t-stat / etc.......all Toyota parts. I installed the t-stat with the jiggle valve at 12 o'clock as per the Hayne's manual, Safetydang's video, etc. Wouldn't you know....my temp is running at 198-202 now.

Tomorrow I will flip the t-stat to have the jiggle valve at 6 o'clock and report back.

its still hard to say, now they could have put the thermostat in backwards, I have seen that more than once.
Now, one thing, do not let the motor overheat. one tip if she starts to run warm, throw your heater on high, its not much but it might help.

Jiggle valve goes down. Search jiggle valve. There is a thread with links to the fsm that will tell you he same. As for the thermostat it is sooooooo easy. Did it and hoses in 30 minutes. I installed jiggle valve at 6 o'clock. When I removed the original it was at 7 o'clock. It's a one owner truck so I thought that was wierd. I did research and it goes down.

Rehashing and thread...

Just did my t-bone the weekend.

New water pump and tstat. Old one ran at 195-204.

New one runs at 204.8 - 208.4. It even hit 210 once. I installed my jiggle at the 12 o'clock like the one that was in there previously.

I want to flip it to the 6 o'clock. But i had a couple questions.

1) Do I have to drain the cool to flip the tstat?

This pink premixed stuff is expensive. Is there a way to clamp the hoses and pull the housing real fast and flip the tstat?

2) Since the current tstat is a week old, do I have to replace rubber gasket? Or is it still good since it's not very old?

I appreciate the help!

You may want to drain a little out to get the fluid level below the t stat. Just put it in a clean container. Switch it to the 6 O'clock, and replace. Shouldn't take but 20 minutes start to finish.

If you don't drain it out it will flow out the opening and you will lose the fluid anyway. Best to keep it.
