I wanted a low temp thermostat. Nengun and greenline would take too long and cost too much so I had a flick through the TRIDON catalogue.

After searching for about an hour, i found a thermostat with almost perfect dimensions. Part Number: TT228-170P Its 2mm smaller in outside diametre than the Toyota part (90916-03093) but the rest is exactly the same as stock. Whats a bonus is you can get the thermostat in several operating temps. 68 degrees, 77 degrees, etc...


I installed the 170F degrees (77° celcius). Works a treat and only cost me $35!

Here she is on the left compared to the old stocka on the right:





Yes the water opening diametre is a little smaller and the spring assembly looks different, but it all works perfect.

Hope this helps some of you guys out.
