Classification: Reference: EL17-002 Date: NTB17-031 March 16, 2017 2016 – 2017 TITAN XD; COOLANT HEATER (ENGINE BLOCK HEATER) INSTALLATION APPLIED VEHICLES: APPLIED ENGINE: 2016 – 2017 Titan XD (A61) Cummins (5.0L V8) Diesel SERVICE INFORMATION Some customers may want to use a coolant heater (engine block heater) for their vehicle when ambient temperatures are below 32°F (0°C). 2016 Titan XD: Some were not equipped from the factory with a coolant heater or cord. Some were equipped with coolant heater, but not a cord. 2017 Titan XD: Was equipped from the factory with a coolant heater, but some were not equipped with the coolant heater cord. If a customer chooses to purchase the parts and labor for installation of a coolant heater and/or coolant heater cord, use the Service Procedure in this bulletin for installation instructions. NOTE: Refer to Owner’s Manual for coolant heater (engine block heater) operation instructions. Coolant heaters (engine block heaters) will operate continuously when plugged into the correct voltage electrical socket. Operate coolant heater only when the ambient temperature is below 32°F (0°C). When using the coolant heater the vehicle should be parked on a level surface. If a level surface is not available, the vehicle should be parked with the front of the vehicle lower than the rear (nose down). CAUTION: Use of the coolant heater when parked with the front of the vehicle higher than the rear (5 degrees or more) may cause the coolant heater to become damaged and/or inoperative. Nissan 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. 1/8 SERVICE PROCEDURE 1. Record (write down) any customer settings that will be lost when the battery is disconnected. Refer to the Electronic Service Manual (ESM) section PG-Power Supply, Ground, & Circuit Elements, for a listing of systems that may lose settings or memory when disconnecting the 12V battery. Look in the PG section index for ADDITIONAL SERVICE WHEN REMOVING BATTERY NEGATIVE TERMINAL. This list often includes items such as audio, HVAC, power windows, clock, etc. 2. Disconnect the negative battery cable from both batteries. 3. Remove the left side (driver side) battery from the vehicle. If needed, refer to the ESM, Section PG-Power Supply, Ground, & Circuit Elements, for battery removal. 4. Drain the engine coolant (if coolant heater is being installed). Refer to the ESM, Section CO-Engine Cooling System, for coolant draining information. Drain the coolant into a clean drain pan. The drained coolant will be reused/reinstalled back into the cooling system. CAUTION: Do not spill coolant on the drive belt. 5. Unbolt the power steering pump from its mounting bracket. Do not drain the power steering fluid. The pump just needs to be moved to access the coolant heater port. Refer to the Electronic Service Manual (ESM), Section ST-Steering System, for pump removal information. Figure 1 shows the power steering pump positioned out of the way. 2/8 Power steering pump Figure 1 NTB17-031 NOTE: With the power steering pump positioned out of the way, you will have access to the coolant heater port plug shown in Figure 2. Steps 6, 7 and 8 are needed only if a coolant heater is being installed. 6. Remove the coolant heater port plug; use a 12 mm hex tool. Coolant heater port plug Figure 2 7.
