Some Santa Fe (CM) vehicles may have an engine that potentially leaks oil from the front cylinder bankâs 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. The service procedure contained in TSB 23-01-076H (or latest version) is summarized below:
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.
