Procedure
1. Remove engine undercover on right side only.
2. After the engine coolant and engine components have cooled down, drain engine coolant from radiator and remove threaded freeze plug. (For plug location refer to application chart section "Location".
3. Apply a thin layer of gasket sealant (Nissan P/N 999MP-A7007) on both sides of the gasket. Slide it over the engine block heater threads.
4. Install engine block heater to engine block being careful not to damage the threads. Torque heater to 32 +/- 4 ft.lb. (4.5 +/- 0.5 kg.m.).
5. Connect power cord to engine block heater and route cord as follows:
A. From engine block heater route cord down, between drive shaft and engine block, toward front of the vehicle between exhaust pipe and engine oil pan (Figure 2). Attach cord to engine block ear on left side of compressor with a tie wrap. Continue routing cord along the left side of the compressor and attach it to the compressor high pressure hose (rubber portion) with a tie wrap.
NX: Route cord under radiator core support and out to the front of the vehicle through right side opening of front lower grille. Secure cord to grille with tie wrap (Figure 3).
Sentra: Route cord up and toward the right, through the opening behind right head lamp, between the two legs securing the front grille to the radiator core support. Secure cord to vertical member of front grille with a tie wrap (Figure 4).
CAUTION: Make sure that power cord is not routed close to or touching any of the vehicle's moving parts or hot surfaces.
6. Refill cooling system; pressurize to radiator cap relief pressure and check for leaks. Operate engine to check further for leaks. Refer to manufacturer's Service Manual "Engine Cooling System" section.
NOTE: It is recommended that low phosphate anti-freeze be used and that a maximum anti-freeze/water mixture ratio of 50/50 be used. Refer to Nissan Owner's Manual "Engine Cooling System" section.
7. Reinstall engine undercover.
8. Use cable end protector cap when heater is not plugged into power source.

PROCEDURE
1. Drain coolant and remove specified core plug. (Do not use a screw type freeze plug puller or similar tool to remove the plug as it may cause damage to the engine block.) Remove freeze plug by positioning a flat blade screwdriver against the plug's recessed area and hammering it repeatedly with very short strokes until the freeze plug is loosened and turns. (Do not hammer freeze plug on the edges as this could damage engine block.) Then remove plug with needle nose or combination pliers.
2. Thoroughly clean core plug hole, removing any burrs, compound, paint or rough spots. (If necessary use fine emery paper being careful not to score surface.)
3. Apply a coating of grease to the heater "O" ring and machined surface of the engine block hole to facilitate installation and prevent "O" ring damage.
NOTE: DO NOT USE GASKET GLUE - it hardens, preventing proper seal and eventually causes leaks.
4. Refer to element direction shown in chart. Insert heater with element pointing in proper direction and push flush to block.
5. Tighten screw to 14-19 in.lb.
6. Install the power cord and route it to the front grille, taping it and securing it with plastic tie wraps where necessary, to insure that the cord does not touch any hot pipes, engine components or moving parts.
7. Refill cooling system, pressurize to radiator cap relief pressure and check for leaks. Operate engine to check further for leaks. Refer to manufacturer's Service Manual "Engine Cooling System" section.
NOTE: It is recommended that low phosphate anti-freeze be used, and that a maximum anti-freeze/water mixture ratio of 50/50 be used. Refer to the Nissan Owner's Manual "Engine Cooling System" section.
8. Use cable end protector cap when heater is not plugged into power source.
WARNING: Before connecting heater to power source, make sure that cooling system is filled with recommended coolant (see appropriate Service Manual).
