Overall assembly performanceEach unit run with warm coolant (90°C) for 15 min — flow, noise, and seal integrity recorded
Installation & Maintenance Recommendations

Before installation:

  • Drain coolant completely and inspect for rust or debris. Flush the system if old coolant is contaminated.
  • Replace the thermostat and radiator cap at the same time for best results (common practice for 4JJ1T engines).

Installation steps (abbreviated):

  1. Remove drive belt, fan, and old pump. Clean mating surface thoroughly.
  2. Compare new pump's impeller depth and flange alignment with old unit.
  3. Apply the included paper gasket (no extra sealant required).
  4. Torque mounting bolts to 12 Nm in a cross pattern.
  5. Reinstall fan and belt. Tension belt to 6-8 mm deflection at mid-span.
  6. Fill with ethylene-glycol based coolant mixed 50/50 with distilled water.
  7. Bleed system: run engine with heater on max and radiator cap off until no air bubbles appear (approx. 10-15 min).

Maintenance:

  • Replace coolant every 2 years or 60,000 km.
  • Inspect pump weep hole for any sign of coolant leakage every oil change.
  • Listen for grinding noise — indicates bearing failure.
Packaging & Supply
  • Sturdy carton with foam insert and moisture-barrier bag (prevents corrosion during sea freight)
  • Each pump individually packed with gasket and O-ring in a separate labeled bag
  • Bulk wholesale packing: 10 units per master carton, layer pads for pallet
