2ZR Turbo Yaris

Trans thermostat and plumbing done

The circuit is now complete. Looking forward to starting the car - will be a while yet though - and checking for leaks. I just have two mounting points using the rubberized "P" clips left for the hoses which requires pre-drilling and using self tapping screws - the metal is a touch too thick to self tap. There was one spot there the inlet and outlet hoses are touching, so I cut a short section of pipe, wrapped one of them and ziptied the rubber hose piece on. Everywhere else there is no contact and room for movement.

The sensor is installed on the outlet of the factory in-rad cooler running to the inlet of the aftermarket cooler. If anything, this should keep the fluid cooler than putting the sensor after the aftermarket cooler.





I'm going to wrap the sensor with some of the fiberglass reflective tape provided with the turbo kit. The sensor is about an inch away from the lower rad hose, which probably wouldn't be an issue, but I'll play it safe.

Do you by any chance know what the factory optimal trans temp is? The reason I ask is because with the thermostat installed before the aftermarket cooler is potentially could be keeping the fan on constantly if your thermostat is a low temp set point than what the factory rad cooler typically keeps it at.

It might be a wash either way but I just figured less time the fan is running, less electrical load and stress to the fan.
