What This Product Does
The housing accommodates the thermostat insert within the engine cooling circuit. As coolant temperature changes, the thermostat regulates flow between the engine and radiator, helping the engine warm up and maintain its operating temperature. This is a coolant-flow control assembly rather than a temperature sensor.

Functions

• Houses the thermostat insert.
• Controls coolant passage through the radiator circuit.
• Supports temperature regulation during warm-up and normal running.

Technical Details

• Part reference: 95810603202.
• Supplied configuration: thermostat housing with thermostat insert.
• Cayenne diagram application: 92A (958), 3.0L HYBRID, 2011–18; identifiers 06EC, CGEA, CGE, CGFA and CJT.
• Panamera diagram application: 970 (G1), 3.0L HYBRID, 2012–16; identifiers CGEA, CGE and CGFA.
• The coolant pump, pulley, cover, seal and fasteners are identified separately in the assembly diagrams.

Symptoms of Fault

• Coolant seepage or dried deposits around the housing.
• Repeated coolant-level warnings.
• Higher-than-usual or unstable engine temperature.
• Extended warm-up time.
• Reduced cabin heating when the engine remains too cool.
• A sweet coolant odour or visible fluid beneath the vehicle.

Why Replacement Matters
A leaking housing can allow coolant loss, while a sticking thermostat may restrict circulation or keep the engine running too cool. Renewing a confirmed faulty assembly addresses these faults. Inspect adjoining connections and sealing surfaces during the repair, and follow the vehicle-specific coolant filling and bleeding procedure. OE Match's Porsche-focused replacement programme uses original references and application details to guide component selection.

FAQs

Is the thermostat insert included?
Yes. The supplied configuration includes the housing and thermostat insert.

Do these symptoms confirm thermostat failure?
No. Leaks elsewhere, low coolant and temperature-sensor faults can produce overlapping symptoms. Establish the cause before replacing parts.

How can a suspected housing leak be checked?
Inspect for dampness and coolant deposits around the assembly. A cooling-system pressure test can help locate the source.
