What This Product Does:

  • Returns coolant from the PDK gearbox cooling circuit
  • Maintains continuous coolant flow through the transmission cooler
  • Helps regulate gearbox operating temperature
  • Protects internal transmission components from excessive heat
  • Supports smooth shifting and overall transmission performance

Symptoms Of Wear Or Failure:
  • Coolant leaks near the transmission or under the vehicle
  • Low coolant warning light
  • Frequent coolant top-offs
  • Transmission temperature warning message
  • Gearbox running hotter than normal
  • Transmission entering limp mode due to overheating
  • Coolant residue or staining around hose connections
  • Cracked, brittle, swollen, or soft hose material
  • Steam from beneath the vehicle in severe cases

Why Replacement Matters:
  • Replacing a worn PDK gearbox coolant return hose is important because it ensures coolant can properly circulate through the transmission cooling system. Over time, heat and pressure can weaken the hose, leading to cracks, leaks, or restricted coolant flow.
  • If the hose fails, coolant loss and reduced circulation can cause the PDK transmission to overheat. This may lead to reduced performance, warning messages, limp mode activation, or internal transmission damage.
  • Installing a new return hose helps prevent leaks, maintain stable gearbox temperatures, and protect the PDK system for long-term reliability and smooth operation.
