ENGINE SUPPORT TOOLS
APPLIED VEHICLES:

2020-2024 Sentra (B18)

SERVICE INFORMATION
A new Engine Support Bracket is now available to allow the CVT to be removed from the
APPLIED VEHICLES without having to remove the engine.
The procedure in this bulletin is different from the procedure currently in the ESM, which
will be updated with this information at a later date.
Please refer to the SERVICE PROCEDURE in this bulletin for information on how to use
these new tools.

Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE
To avoid the risk of death or severe personal injury, do not remove the radiator cap when
the engine is hot. Serious burns could occur from high pressure engine coolant escaping
from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter turn to allow
built-up pressure to escape. Carefully remove the cap by turning it all the way.
To avoid the risk of minor personal injury or property damage:


Perform when the engine is cold.



When replacing the TCM and transaxle assembly as a set, replace the transaxle
assembly first and then replace the TCM. Refer to "Description" in the Transaxle &
Transmission section of the ESM.



When replacing the transaxle assembly, perform "ADDITIONAL SERVICE WHEN
REPLACING TRANSAXLE ASSEMBLY." Refer to "Description" in the Transaxle &
Transmission section of the ESM.

HINT: When removing components such as hoses, tubes/lines, etc., cap or plug openings
to prevent fluid from spilling.
