Part 1: Preparing for Installation
This manual contains installation instructions for the
VR70 system (V900085) and the VR140 system
(V910005). There are differences in the installation.
Make sure that you read these instructions before
beginning the installation to identify the specific steps
that apply to your system.
□ Clean around the fuel filter, injection pump, turbocharger and air
intake. Also clean the front of the engine to ensure that the
bracket mounts properly.
□ Disconnect the vehicle batteries and drain the cooling system.
□ Cut off the plastic locking rings from the radiator hoses and
remove the hoses, the steel tube that is part of the upper hose
assembly and the hoses from the expansion bottle.
Be careful that you do not cut through the hose when
you are cutting the rings, as the hoses will be reused.
□ Remove the six bolts holding the expansion bottle in place,
remove the expansion bottle, then replace and tighten the two
OEM bolts in the front of the mounting bracket.
□ Remove the air cleaner and all ducting, including between the
turbocharger and the intake.
□ Remove the driver side intercooler tube.
Cover the opening on the engine and the opening on
the turbocharger with plastic covers or tape to protect
them from contaminants.
□ Remove the left air cleaner mounting bracket and the two front
bolts on the right air cleaner mounting bracket.
