Auberins gauge install 1kzte (water temp and EGT)
Posted: Sat Nov 01, 2014 8:49 pm
So I get a lot of useful info from this site so I thought I'd post today's efforts as it may help someone else in the future. When I say "we" I mostly mean Mudbugga as I just stood around fetching spanners and stuff and tidying up 
We ordered the auberins EGT gauge which came as a bundled set with the K type probe and a temp gauge which came with a PT100 sensor. This is on a 1KZTE engine for a Prado 3.0L diesel.
We removed the exhaust manifold, marked and drilled a 7mm hole for cutting a M8x1 thread to match the EGT probe. The heat shield also needs a hole to allow the wire feed out.
For the water sensor probe we found a bung in the head on the intake side. The sensor comes with a 1/8 NPT thread. I took both bung and sensor to a hydraulics shop (Martins) and they sold me an adaptor off the shelf for $5 We were a bit worried the probe didn't stick out far enough into the water flow but it seems to be working ok for now..
Both sensors wires went through the firewall where the heater cable goes.
We installed the gauges into the trinket tray under the stereo. I ordered the enclosure boxes from auberins and they fit real nicely in the trinket tray held in with a piece of double sided tape.
The wiring in was pretty straight forward following the instructions: power,ground,sensor, and a feed from the headlamps which makes the gauges dim when you turn the lights on.
The only bit where we struggled was when we fired them up they were reading crazy numbers. Like 33 Celsius water whilst hot. We scratched our heads a bit until we realised that you needed to program the gauges so they matched the sensor type! Once we worked this out using the "Input Type" setting in the menu we were fine.
Here are some pics...
Mudbugga is a good bugga!
. Cheers

- Adaptor for water sensor
- EGT fitting
- Heat shield drilled
- Exhaust manifold refitted
