PROCEDURE:
1. Check the condition of the vehicle's lower radiator hose. (See Figures 5, 7, 9 and 11 for identification.) If hose is cracked or softened, replace it. If it is in good condition, proceed to Step 2.
2. Working from underneath the vehicle, remove the engine undercover and set it aside.
3. Drain coolant from the engine by opening the drain plug on the bottom of the radiator.
4. Loosen the clamps at both ends of the lower radiator hose. Observe how the hose fits and its shape as installed in the vehicle. Mark the engine end of the hose with tape or chalk. Remove the hose from the vehicle.
(Stanza: remove end of hose connected to radiator only.)
5. 200SX: Refer to Figures 5 and 6 Measure 15 inches from the engine end of the hose and make a mark. From this mark measure 1-1/2" towards the radiator end and mark (Fig. 6). Using these two marks, cut a 1-1/2" section from the hose. Be sure the cut piece is on a straight section of hose and try to keep the hose in its original shape.
STANZA: Refer to Figures 7 and 8 Mark hose in the middle of lower section of hose inclined at a 45 angle (Fig. 8). From this mark measure 3/8" toward the radiator end and toward the engine end and mark both places. Using the last two marks, cut a 3/4" section from the hose. Be sure the cut piece is on a straight section of hose and try to keep the hose in its original shape.
Truck/Pathfinder: Refer to Figures 9 and 10 Mark hose in the middle of straight section of hose connected to the engine (Fig. 10). From this mark measure 3/8" to 1/2" toward the radiator end and toward the engine end and mark both places. Using the last two marks cut a 3/4" to 1" section from the hose. Be sure the cut piece is on a straight section of hose and try to keep the hose in its original shape.
Truck (KA24E): Refer to Figures 11 and 12 Mark hose in the middle of lower half of the straight section (inclined portion of hose) (Fig. 12). From this mark measure 1/2" toward radiator end and toward the engine end and mark both places. Using the last two marks, cut a 1" section from the hose. Be sure the cut piece is on a straight section of hose and try to keep the hose in its original shape.
6. Insert the lower hose heater into the cut ends of the hose (see appropriate drawing). Slide a hose clamp (provided in the kit) over the hose on each end and tighten over the lower hose heater. Again try to keep the hose in its original shape. NOTE: Do not remove electrical cord from heater.
7. Reinstall the lower radiator hose (with lower hose heater) into the vehicle using the original clamps. Tighten all clamps. Make sure that the hose is installed in its original position.
8. Route cord out around the radiator. Use plastic tie wraps to hold the wire away from hot or moving parts.
9. Refill radiator with coolant fluid. Start engine and run to expel any air trapped in the system. Check coolant level and add if required.
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.
10. Check all hose connections for leaks. Tighten clamps if necessary. Reinstall engine undercover.
11. Use cable end protector cap when heater is not plugged into power source.
