DESCRIPTION
This document will guide the user through the changes of the dielectric grease/coatings used in certain areas on all International vehicles built after 1/8/2018.
International's Electrical Engineering Team made this change to improve the longevity of the OEM coatings and to improve applications at the factory.

SYMPTOM(s)
On all International vehicles built after 1/8/2018; the color/type of dielectric grease being applied at the factory on all major electrical points has changed
depending on the location of the connection on the truck. (Please see pictures below for reference.) International Service Part Numbers will be added to this
article once available and will be orderable from Kemcrest through PDC. Until that update is available please refer to the service part section of this article to
order the grease/paint coating directly from the manufacturer.

Note: For all field repairs, service shops can continue to use Grafo grease or equivalent where it was originally applied.
Grafo may also be applied over the blue grease or red paint if Nanomech products are not available at the time of service.
Every effort should be made to reapply the same product that was originally applied by the factory.

New Changes for Color and Type of Dielectric Grease Coatings for Electrical Interconnections

EXAMPLES:

Battery box interconnections will use BLUE dielectric grease coating.
Blue TriboTuff Lithium Grease

Engine Trim interconnections will use RED dielectric paint coating.
Red GuardX Enamel Coating

Grease may cause skin & eye irritation. Wear protective clothing, gloves, and glasses.

Wash exposed skin that may have come in contact with grease thoroughly after handling.

REPAIR STEP(s)
Fully remove and clean all old dielectric grease/ paint coating from components during repair/disconnection of electrical joint. Apply the appropriate
grease/paint coating to the electrical connection components as needed after all service work is complete. Follow manufacturer's instructions for application
and clean-up of grease/ paint coating.

Assembly Instructions
Blue Grease in Battery Box
1. Clean battery terminals with a wire brush.
2. Clean battery terminals and battery studs with a liberal amount of electrical contact cleaner.
3. Dry battery terminals and battery studs with compressed air.
4. Apply dielectric grease to battery cable terminals.
5. Connect all battery terminals to proper battery studs.
6. Tighten battery terminal nuts to the proper specification 12 to 15 lb-ft (16.3 to 20.3 Nm)

The blue dielectric grease should be applied prior to assembly and torque.
Battery stud nuts are prevailing torque nuts, and should be replaced whenever they are removed.

Red Enamel on Starter, Frame, Alternator, and more
1. Clean battery terminals with a wire brush.
2. Clean battery terminals and component studs with a liberal amount of electrical contact cleaner.
3. Dry battery terminals and component studs with compressed air.
4. Connect all battery terminals to proper component studs.
5. Tighten battery terminal nuts to the proper specification.
6. Apply red enamel to the terminals as studs / bolts.
