Product Information
Product Information

Every car has its weak points one of the items to keep an eye on is the coolant recovery tank. Over time it becomes brittle and has a tendency to crack and leak coolan. A simple preventative measure is to replace your tank with an OE Match coolant expansion tank

Fits

  • Porsche 970 Panamera MKI
  • Porsche 970 Panamera MKII

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The reservoir accommodates changes in coolant volume during engine warm-up and cooling. It forms part of the sealed cooling circuit, working with the pressure cap and connected hoses.

Functions

  • Holds coolant within the cooling circuit.
  • Provides space for thermal expansion.
  • Accommodates coolant as its volume changes with temperature.

Technical Details

  • Part reference: 97010615103.

Symptoms of Fault

  • Unexplained, gradual coolant loss.
  • Repeated coolant-level alerts.
  • A sweet odour around the reservoir.
  • Dried deposits along seams or hose connections.
  • Fine cracks or damp patches on the tank.
  • Coolant traces appearing after parking.
  • Gurgling associated with low coolant or trapped air.
  • An unexpected increase in engine temperature.

Why Replacement Matters

Repeated heating and cooling can leave an ageing reservoir brittle, allowing small fractures or seam leaks to develop. Renewing a confirmed faulty tank addresses that source of coolant loss. Inspect the cap, hoses and clamps at the same time, since nearby faults can produce similar symptoms.

FAQs

Does a coolant warning prove the tank has failed?
No. Check the actual level and investigate leaks, the sender and its connections before deciding which component needs renewal.

How can a small leak be located?
Inspect seams and hose necks for dried deposits. A cooling-system pressure test can help identify seepage that is difficult to see.

Can the cap also cause coolant loss?
Yes. A defective pressure cap may allow coolant to escape, so it should be checked alongside the reservoir.

When should the coolant level be checked?
Allow the engine to cool fully before checking or opening the reservoir. Never remove the cap while the system is hot.
