1.

The thermocouple monitors

the temperature of the exhaust

gases entering the turbocharger

at the turbine housing. Installation

requires that the exhaust manifold

be drilled near the manifold outlet.

It is recommended that the manifold

be removed from the engine to

thoroughly clean out all metal chips

from drilling. If the manifold is not

removed from the vehicle, all chips

must be removed from the manifold.

This may be accomplished by using

a magnet to extract the chips after

drilling. The tap should be greased

before use and the chips again

removed with a magnet. All metal

shavings must be cleaned from the

manifold to avoid turbine damage.

2.

To access the exhaust manifold,

remove front passenger wheel well by

removal of plastic retainers.

3.

On the passenger side, remove the

hardware retaining the turbine inlet

exhaust pipe to the exhaust manifold.

Then, remove the exhaust manifold

from vehicle. Pay special attention to

the orientation of the manifold outlet

gasket. Retain the hardware and

gaskets for re-assembly.

4.

Center punch and drill through the

passenger side exhaust manifold into

the rear passage at the location shown

in Figure 18. Use an “R” drill bit,

keeping the drill perpendicular to the

manifold surface.

5.

Tap the drilled hole with a

1

8

” NPT

pipe tap. Check the thread depth as

you tap by periodically removing the

tap and screwing the thermocouple

insert into the tapped hole. The

thermocouple insert should be tight

and snug when half it’s threads are

screwed into the manifold.

6.

Install the thermocouple insert

into the manifold using anti-seize

compound on the threads. Install the

probe in the thermocouple insert.

7.

Make sure to remove all shavings

from inside the exhaust manifold.

Reinstall the exhaust manifold. Torque

to 28 lb-ft (38 Nm) in the sequence

shown in Figure 18.

8.

Route the thermocouple connector

along the factory harness to the

driver’s side and connect it to the Six-

Gun’s EGT connector. Use the supplied

cable ties to secure the harness.
Note: once the six-Gun Diesel tuner

is powered up at key-on, it will ‘learn’

that a thermocouple is installed and

automatically enable the eGt limiting

function.
If the thermocouple is removed after

being installed and run on the vehicle,

the Six-Gun Diesel Tuner will assume

that the sensor or connection has

gone bad and will cease adding power

while triggering the [2,3] diagnostic

code (see Troubleshooting Section). To

ensure that the Six-Gun Diesel Tuner

operates properly after removing a

previously installed thermocouple,

see the ‘Clearing Learned Information’

Section 9. EGT limiting will not be

operational and excessive EGTs may

develop at higher power levels.
