I see some alternate part#s and manufacturers listed online for the 2 stage 22re thermostat (part 9091603070), examples here:

I checked the diameter (52mm) and temp (190) all is the same, if it looks like a duck is it a duck?

 

I am running Murray dual stage thermo #41492 in my 22RE with good results.

About $9 at an O'Reillys auto near me.

 

Bought mine from LCE performance and
Amazon.com also has them 2 stage 190*F.
2-Stage Thermostat OEM 22R/22RE (190 Degree)
OEM Toyota P/N: 90916-03070

 

Nice. I couldn't find any info about options for the $45 term but you ve done the homework it seems, thanks

 

Also got mine from LCE. It was listed as same PN above for $39.
However, it came in a TAMA packaging. LCE says, it's the OEM; Meaning that if you may be able to buy the TAMA T-Stat elsewhere for less.
There is already a two-stage / Dual-stage Thermostat Thread here.

 

👍 Thanks sorry didn't see it before.

 

N.P.
Yeah, the search Thread or Posts function sucks.
Try using the custom "Google" search on the Search pull-down menu. (like below)...
TAMA part number is in that thread
