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 be
removed with a magnet. All metal
shavings must be cleaned from the
manifold to avoid turbine damage.
2.
Access the exhaust manifold from
the front passenger fenderwell.
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 37. 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 37.
8.
Route the thermocouple connector
along the factory harness to the
driver’s side and connect it to the
EconoMind’s EGT connector. Use
the supplied cable ties to secure the
harness.
Note: Once the EconoMind 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 EconoMind 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
EconoMind Diesel Tuner operates
properly after removing a previously
installed thermocouple, see the
clearing Learned Information Section.
EGT limiting will not be operational and
excessive EGTs may develop at higher
power levels.
9.
Install the driver’s side and
passenger’s side fenderwells. The
charge air temperature before the CAC
approaches 400°F at full load. So, take
care to route wiring away from the
driver side boost tube and re-install
the factory wire retainers on the
fenderwell cover.
