Install and Attach the EGT Probe

It is necessary to tap a small hole into your exhaust manifold to insert the EGT sensor. The
EGT probe must be mounted before the turbo for the Juice safety features to operate
properly.
WARNING When installing the EGT Thermocouple, wear eye protection and
protective clothing to protect from getting metal chips in your eyes. Also, since exhaust
manifolds can be very hot, allow the engine to cool before drilling. When working under
the vehicle, make sure the park brake is set. If the vehicle must be raised, carefully follow
the stand and vehicle safety guidelines for placement and use of jacks and stands.
CAUTION: One effective way to avoid metal fragment contamination in your engine
manifold is to apply grease in the tip of the drill bit and threads of your tap tool when
drilling/tapping the hole in your manifold. Reduce pressure on the drill when the drill
breaks through the manifold wall to reduce risk of pushing metal chips into the manifold.
1. Obtain a 1/8" National Pipe Tap (NPT) available from your hardware store. Drill a
21/64" (5/16" optional) hole through the manifold wall, and then use the pipe tap to cut
the threads. Follow the instructions provided with the tap. The pipe tap is tapered, so
you will only want to turn the tap until the bottom threads of the tap are slightly deeper
than flush with the inside of the exhaust manifold wall. Use caution not to tap too deep
since this would cause the thermocouple fitting and probe to seat too deep. (tap deep
enough to allow 3+ full threads of fitting to seat in manifold)
2. After the manifold has been drilled and tapped, remove the fitting from the
Thermocouple and install by tightening the tapered thread end into the manifold with a
9/16" end wrench. (Ideally the tip of the fitting would be less than or flush with the
inside of the exhaust flow path.) Tighten the fitting so that it is securely seated. Then
install the probe into the fitting, and tighten the top nut of the fitting just tight enough to
keep the probe firmly mounted. Make sure that the probe cable is positioned to allow
best path and minimal bending, for cable routing to the top of the engine compartment.
