ALTIMA

  1. On models equipped with automatic A/C, turn ignition off. Turn ignition on, then after 5 seconds, press the hot button 3 times the defrost button 2 times. Climate control panel should display "43", indicating that heater valve is open.
  2. On models equipped with manual A/C, turn ignition on. Set temperature control to maximum heat position. Wait 10 seconds, then turn ignition off.
  3. On all models, open air relief plug. (Scheme 8) Fill radiator slowly to allow air to escape. Close air relief valve when coolant starts to flow out of air relief hole. Fill coolant reservoir to MAX mark.
  4. Reinstall radiator cap. Start and warm engine to normal operating temperature. Race engine 2-3 times under no-load. Turn engine off. Add coolant after engine cools down. Check drain plug and air bleed plug for leaks.

MAXIMA

Fill radiator slowly to allow air to escape. Fill coolant reservoir to MAX mark. Install radiator cap and warm engine to normal operating temperature. Race engine 2-3 times under no-load. Turn engine off. Add coolant after engine cools down. Check drain plug for leaks.

PATHFINDER & PICKUP

  1. Before filling cooling system, ensure heater valve is open to allow coolant flow through heater core. When filling cooling system, ensure air relief plug is loose to allow trapped air to exit system. (Scheme 9)or (Scheme 10). Tighten air relief plug after filling cooling system.
  2. Install radiator cap. Warm engine to normal operating temperature. Race engine 2-3 times under no-load. Turn engine off. Add coolant after engine cools down. Check air relief and drain plug for leaks.

QUEST

  1. Loosen engine and radiator air relief plugs. Remove heater pipe air relief cap. (Scheme 11) Connect one end of 40" clear, heat resistant hose to heater pipe relief. Fill coolant reservoir to MAX mark and place hose from heater pipe air relief into coolant reservoir. Ensure hose is below coolant level at all times.
  2. Slowly add coolant through radiator filler neck, allowing several minutes for air to escape. When coolant starts to drip from radiator air relief plug, close plug. Tighten plug to 15-19 ft. lbs. (20-26 N.m).
  3. Continue adding coolant while gently moving upper radiator hose up and down until coolant level no longer drops in filler neck. Place wire under radiator filler cap negative pressure relief valve. (Scheme 13) DO NOT install cap at this time.
  4. Start engine and run at 2000 RPM for 10-15 minutes or until lower radiator hose becomes hot. If coolant comes out of engine air relief plug, close plug. Tighten plug to 15-19 ft. lbs. (20-26 N.m). If coolant in radiator neck lowers, add coolant. If coolant overflows filler neck, install radiator cap (with wire installed).
  5. Close engine air relief plug if not already done. Stop engine and allow to cool down completely. Refill radiator and reservoir as necessary. Ensure radiator cap (with wire) is installed. Start engine and warm to operating temperature. If engine temperature raises above normal, stop engine and repeat this step. NOTE: Ensure coolant level in reservoir tank is maintained at MAX mark for the following steps.
  6. On vehicles without rear heater, ensure temperature control lever is in full HOT position. Select any fan speed and mode except OFF. Run engine at 3000 RPM for 5 minutes or until outlet air is hot. Repeat this step at least 3 times. Ensure no water noise is present in heater core.
  7. On vehicles with rear heater, run engine at 3000 RPM with front temperature control lever in full COLD position. Move rear temperature control lever to full HOT position. Select any fan speed except OFF. Run engine 5 minutes or until rear outlet air is hot.
  8. Move rear temperature control lever to full COLD position. Move front temperature control lever to full HOT position. Select any fan speed and mode except OFF. Run engine 5 minutes or until front outlet air is hot. Repeat steps 7) and 8) at least 3 times. Ensure no water noise is present in front or rear heater core.
  9. On models equipped with automatic A/C, operate engine at 3000 RPM with front climate control set at 60°F and rear A/C control unit temperature switch to full WARM position and fan on for 5 minutes or until rear outlet air is hot. Turn rear control unit to full COOL position and set front climate control to 90°F until front outlet air is hot. Repeat process at least 3 times until no water noise is heard at heater core.
  10. On all models, stop engine. Fill coolant reservoir to MAX mark. Let engine cool down. Remove radiator cap and remove wire from negative pressure valve. Fill radiator as necessary and reinstall radiator cap. Remove hose from heater pipe relief and quickly install cap on pipe. Fill reservoir as necessary and install reservoir cap.

SENTRA & 200SX

  1. Set heater control to HOT position. Open air relief plug. (Scheme 12) Fill radiator slowly to allow air to escape. Close air relief plug when coolant starts to flow out of air relief hole. Fill coolant reservoir to MAX mark.
  2. Reinstall radiator cap with pressure relief valve open. (Scheme 13) Start and warm engine to normal operating temperature. Increase engine speed to 2500 RPM for 10 seconds then return to idle. Repeat 2-3 times. Turn engine off. Add coolant after engine cools down. Repeat procedure 2 or more times.
  3. Check coolant level. Install proper radiator cap. Warm engine to normal engine temperature. Move heater control at several positions between HOT and COLD. Increase engine speed to 4000 RPM. Listen for coolant flow at heater valve. If coolant flow is heard, repeat step 2) until coolant level no longer drops. Check air relief and drain plug for leaks.

240SX

  1. Turn ignition on. Set temperature control to maximum heat position. Turn ignition off after air mix door moves to HOT position.
  2. Open air relief plug. (Scheme 14) Fill radiator slowly to allow air to escape. Close air relief valve when coolant starts to flow out of air relief hole. Fill coolant reservoir to MAX mark.
  3. Reinstall radiator cap. Start and warm engine to normal operating temperature. Race engine 2-3 times under no-load. Turn engine off. Add coolant after engine cools down.
  4. Check coolant level. Warm engine to normal engine temperature. Move heater control to HOT position. Increase engine speed to 4000 RPM. Listen for coolant flow at heater valve. If coolant flow is heard, repeat step 1) until coolant level no longer drops. Check air relief and drain plug for leaks.

300ZX

  1. On models equipped with automatic A/C, turn ignition off. Turn ignition on, then press both AUTO and OFF switches for 5 seconds, then press AUTO switch one time. Climate control panel should display "75". Wait 10 seconds then turn ignition off.
  2. On models equipped with manual A/C, turn ignition on. Set temperature control lever to maximum hot position.
  3. On all models, open air relief plug. (Scheme 15) Slowly fill radiator to allow air to escape. Close air relief valve when coolant starts to flow out of air relief hole. Fill coolant reservoir to MAX mark.
  4. Reinstall radiator cap. Start and warm engine to normal operating temperature. Race engine 2-3 times under no-load. Turn engine off. Add coolant after engine cools down. Check air relief and drain plug for leaks.
