What This Product Does:

  • Directs coolant flow between the radiator and engine cooling components.
  • Acts as a distribution junction, ensuring coolant is properly routed through the left-side cooling circuit.
  • Helps maintain stable engine operating temperatures by supporting efficient heat transfer.
  • Provides a secure, sealed connection between multiple coolant hoses or pipes under pressure.

Symptoms Of Wear Or Failure:
  • Cracks in the distributor housing or failed seals/O-rings can cause visible coolant seepage.
  • Leaks from the distributor can lead to gradual coolant loss, requiring frequent top-ups.
  • Improper coolant routing or coolant loss can reduce cooling efficiency and cause unstable temperature readings.
  • A noticeable coolant odor near the radiator/front engine area often indicates leakage.
  • Signs may include cracked plastic housing, damaged hose connection ports, degraded O-ring seals, corrosion (if applicable to fittings)
  • Low coolant or temperature warnings may appear if leakage becomes significant.
  • A faulty distributor can cause pressure imbalance in the cooling circuit.

Why Replacement Matters:
  • Prevents coolant leaks that can cause low coolant levels and pressure loss.
  • Maintains proper coolant distribution, ensuring balanced flow through the radiator and engine circuits.
  • Helps prevent engine overheating, which can lead to serious and costly engine damage.
  • Restores system sealing integrity, especially if O-rings or connection ports are worn.
  • Protects surrounding components, as leaking coolant can damage wiring, sensors, belts, and other engine bay parts.
