APPLICATION:

INLINE ENGINE INSTALLATION:

TRANSVERSE ENGINE INSTALLATION:

1. Drain coolant and remove specified core plug (Do not use a screw type freeze plug puller or similar tool to remove the plug. It might cause damage to the engine block).

2 Thoroughly clean core plughole removing any burrs, compound, paint or rough spots (if necessary, use

fine emery paper - be 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).

DO NOT USE GASKET GLUE - Gasket glue hardens preventing proper seal and eventually cause 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 inch pounds torque maximum.

6. Install the power cord and route it to the 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 pans.

7. Refill cooling system, pressurize to radiator cap relief pressure and check for leaks. Operate engine to check further for leaks. Refer to manufacture's recommended procedures.

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 full with recommended coolant
