2 Handle ENGINE BLOCK HEATER with care to avoid damaging the threads. Do not over-torque ENGINE BLOCK HEATER . Ensure that power cord doesn't contact exhaust pipes, sharp edges or vehicle movingparts. Torque removed vehicle parts to proper specifications Figure 1 PROCEDURE1. Remove ENGINE undercover on right side After the ENGINE coolant and ENGINE components have cooled down, drain enginecoolant from radiator and remove threaded freeze plug. (For plug location refer toapplication chart on page 1.)3. Apply a thin layer of gasket sealant (Nissan P/N 999MP-A7007) on both sides of thegasket.

3 Slide it over the ENGINE BLOCK HEATER Install ENGINE BLOCK HEATER to ENGINE BLOCK being careful not to damage the HEATER to 32 + 4 ( + ).3/105. 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. Continuerouting cord along the left side of the compressor and attach it to the compressorhigh pressure hose (rubber portion) with a tie : Route cord under radiator core support and out to the front of the vehiclethrough right side opening of front lower grille. Secure cord to grille with tie wrap(Figure 3).

4 Sentra: Route cord up and toward the right, through the opening behind right headlamp, between the two legs securing the front grille to the radiator core 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 anyof the vehicle's moving parts or hot surfaces. Figure 24/10 Figure 3 Figure 46. Refill cooling system; pressurize to radiator cap relief pressure and check for ENGINE to check further for leaks. Refer to manufacturer's Service Manual" ENGINE Cooling System" : It is recommended that low phosphate anti-freeze be used and that a maximumanti-freeze/water mixture ratio of 50/50 be used.

Drain coolant and remove specified core plug. (Do not use a screw type freeze plugpuller or similar tool to remove the plug as it may cause damage to the ENGINE BLOCK .)

8 Remove freeze plug by positioning a flat blade screwdriver against the plug's recessedarea and hammering it repeatedly with very short strokes until the freeze plug isloosened and turns. (Do not hammer freeze plug on the edges as this could damageengine BLOCK .) Then remove plug with needle nose or combination 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.)7/103. Apply a coating of grease to the HEATER "O" ring and machined surface of the engineblock hole to facilitate INSTALLATION and prevent "O" ring : DO NOT USE GASKET GLUE - it hardens, preventing proper seal andeventually causes Refer to element direction shown in chart.
