CYLINDER HEAD COVER OIL LEAK REPAIR
WITH OIL PROTECTOR INSTALL AND ALTERNATOR VOLTAGE TEST
(SERVICE CAMPAIGN 976)

SUBJECT:

This TSB supersedes TSB 23-01-076H-2 with an updated Op Time for 20DA06R1.

 IMPORTANT
Dealers must perform this service campaign on all affected vehicles prior to customer retail delivery
and whenever an affected vehicle is in the shop for any maintenance or repair.
Access the “Vehicle Information” screen via WebDCS to identify open campaigns.
Description:
Some Santa Fe (CM) vehicles may have an engine that potentially leaks oil from the front cylinder bank’s
valve cover onto the alternator. Oil could damage the alternator resulting in illumination of the charging
system warning lamp and disablement of the charging system. If the vehicle is continually driven without
recharging the battery, the engine will eventually shut off, increasing the risk of a crash. This bulletin
outlines the procedures to inspect for T-joint leakage and install an oil protector to address this issue.
 1. If the alternator voltage is less than 14.0V and there is evidence of oil leak at the T-joint,
replace the alternator, valve cover gasket, and install the oil protector.
 2. If the alternator voltage is greater than 14.0V and there is evidence of oil leak at the T-joint,
replace the valve cover gasket and install the oil protector. Do not replace the alternator.
 3. If the alternator voltage is greater than 14.0V and there is no evidence of oil leak at the T-joint,
install the oil protector. Do not replace the valve cover gasket or the alternator.

ALTERNATOR INSPECTION
Complete a voltage test of the alternator as
described below.
•

•
With the engine running at idle and the
headlamps switched on, with no other
loads switched on, measure the voltage at
B+ terminal of the alternator. In the
condition above, the alternator should
be generating 14 volts or higher.

i

Voltage Test of Alternator
Using a multimeter, connect the positive lead of the
meter to the B+ terminal (A) of the alternator.
Connect the negative lead to a ground, (not the
alternator housing). Use the test method written to
the left to determine alternator replacement.

Information

If the reading is lower than 14 volts, the
alternator may need to be replaced if the
T-joint inspection also does not pass.
