Broken thermostat finger

Hi 2gen club ! The 1gr-fe question is... Where is my broken finger ?

At the end of the summer i notice a little crack that finish in one of the 3 bolt hole so i decided to replace it ( Now i understand why URD sell a Metal housing upgrade) anyone here experience this really bad situation ?

I try to figure out where it most probably stuck but for sure i will need to open water pump to see if the impeller still has good blades and bearing. I have a big thought that the finger isn't stack in the water pump cause it spin really well without any strange sound.

Motor does'nt heat but temperature tends to be a little high when idling (92 celcius or 200 Farheneight )

 

It can be anywhere in the cooling system, I wouldn't be too concerned about it.
It certainly isn't gona hurt the water pump, the impeller is steel and is pretty stout.

 

What URD Metal Tstat
Never heard of it

my plastic lasted a long time and is easy to change.

not sure what you mean by 200F is high. That is probably not high. Gas engines typically run at 190-220F by design.

 

It is kinda elevated for a 2nd gen unless your in 100+ degree weather, 2nd gens run a 180F thermostat. Mine runs around 178-195 depending on how hot it is outside.

Could just be a shitty thermostat if it's not OEM, I've not had very good luck with aftermarket thermostats on alot of stuff lately

 

Mine has hit 190 idling. But typically stays between 180-190.
Never had it hit 200 that I know of.....

 

Mine will exceed 200 on a 100+ degree day if I idle for an extended period with the A/C on but that's the only time I've ever seen it go past 200.

 

It's not been that hot here since I got my program to monitor live data.
And to be honest, I don't even use it much. I just start the truck and drive it.
I figure a light will come on if I "need" to look at something....

 

I imagine if Toyota put down the crack pipe they would’ve put one coolant temp sensor (possibly among multiple) and program it to an upper ceiling limit to trigger a warning if temps too high like other brands have done for a long time.

don’t know if they did this.

or a performance car with gauges which they did not do.
In which case the former among other brands is normally the halfass modern response to the latter.

would not want to be staring at temps. Rather have an idiot light. Ideally would be both. It’s not a space ship.

 

Light or gauge doesn't matter unless there is a warning sound connected to it.
In any case a total loss of coolant often goes un-noticed anyway because coolant temp sensors only work when they have liquid to sense, if they aren't screwed into the block or head they won't tell you your overheating if there's no coolant touching them.

That's one thing Ford got right on many of their engines, they use a cylinder head temperature sensor instead of a coolant temperature sensor although their gauges might as well be idiot lights because they will all sit right in the middle unless something is really far out of operating range.

 

The metal ones are a waste of money,as the factory ones last a LONG time.

 

My temps are 186F most of the time with no noticeable change after a installing a new water pump, fan clutch, thermostat and fresh coolant. In the hot part of the summer here (100~105 ish) it'll creep up to 190. This summer driving across Death Valley in 119F temps with the AC on it creeped up to 209, hottest I've seen on this truck. As long as the mechanicals are good and the radiator isn't clogged these cooling systems work pretty well.
