Information
Engine coolant expansion tank kit.
This kit includes the expansion tank reservoir, pressure cap, and multiple bottles of genuine Porsche coolant/antifreeze - everything needed for a full coolant system refresh
Fits:
Porsche 996 C2 / C4 1997 - 2000
Porsche 996 GT3 MKI 1997 - 2000
Diagram ref no 1, 3, 4, 5, 9, 11, 12.
This kit is suitable for Porsche models that use part 99610614756 as the coolant expansion tank reservoir.
Kit Includes:
• 99610614756 × 1 - Genuine Porsche Coolant Expansion Tank Bottle: Factory-spec reservoir engineered to handle coolant expansion and contraction as engine temperatures fluctuate.
• 99610644704 × 1 - Genuine Porsche Expansion Tank Cap: Provides reliable system pressure control in the cooling system to maintain boiling point and prevent coolant loss.
• 00004330515 × 5 - Genuine Porsche Antifreeze Coolant 1 Litre (Red, Long Life, 5-Year Protection): High-quality coolant concentrate designed to be mixed 50/50 with distilled water for excellent heat transfer, freeze/boil protection, and corrosion resistance.
This kit restores key components of the engine’s coolant reservoir system. The expansion tank collects and stores excess coolant as it expands during heating, the pressure cap maintains proper system pressure to raise the coolant’s boiling point, and the antifreeze delivers long-lasting thermal protection and corrosion control. Using genuine Porsche coolant ensures fluid chemistry is matched to factory specifications.
With age and heat cycling, the original expansion tank and cap can become brittle, cracked, or unable to maintain proper pressure, leading to coolant loss, air ingress, and potential overheating issues. Using genuine Porsche coolant ensures the fluid meets manufacturer chemistry standards for corrosion protection and performance. Replacing these components with genuine parts helps restore the cooling system’s integrity and protects the engine from thermal stress and premature wear.
Replace these components if you notice any of the following:
• Visible cracks, leaks, or discoloration on the expansion tank
• Pressure cap that no longer seals properly
• Coolant that looks contaminated or past its service life
• Unexplained coolant loss or coolant level fluctuations
• Scheduled cooling system maintenance interval reached

Information
Coolant bottle.
The Genuine Porsche coolant expansion tank is the factory-specified reservoir used in the cooling system of Porsche 911 (996) and 997 models. This tank provides the correct fluid volume, pressure stability, and thermal expansion control required to maintain safe and efficient engine cooling. Manufactured to Porsche’s exacting standards, it ensures perfect fitment, correct hose connection points, accurate coolant-level visibility, and long service life even under continuous heat cycling.
Fits:
Porsche 996 3.6L C2 / C4 / C4S 2001 - 2005
Porsche 996 Turbo 2001 - 2005
Porsche 996 GT2 2001 - 2005
Porsche 996 GT3 MKII / GT3 RS 2001 - 2005
Porsche 997.1 2005 - 2008 all models
Porsche 997.2 2009 - 2012 all models
Every car has its weak points, and although the Boxster and 996 has very few, 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 coolant into the rear trunk area in the Boxster. A simple preventative measure is to replace your tank with a genuine Porsche recovery tank.
This product supersedes Porsche's old part numbers:

Diagram ref no 4
As a critical component of the engine cooling system, the coolant level sensor helps prevent overheating and engine damage by providing an early warning before coolant loss becomes a major problem. A faulty sensor can generate false warnings or fail to detect low coolant levels, making replacement an important part of maintaining cooling system reliability.
Manufactured to OE Match specifications, this replacement sensor offers reliable performance, precise fitment and dependable coolant level monitoring.
What Does the Coolant Level Sensor Do?
The coolant level sensor is installed within the coolant expansion tank and monitors the coolant level during vehicle operation.
Its primary functions include:
- Monitoring coolant levels
- Activating low coolant warnings
- Helping prevent engine overheating
- Protecting the engine from coolant loss
- Supporting cooling system diagnostics
- Providing driver alerts
- Improving engine reliability
By detecting coolant loss early, the sensor helps reduce the risk of costly engine damage.
Why Do Coolant Level Sensors Fail?
Coolant level sensors operate continuously in a challenging environment involving heat, pressure and coolant exposure.
Common causes of failure include:
- Age-related electronic wear
- Internal sensor deterioration
- Coolant contamination
- Corrosion of electrical contacts
- Expansion tank deterioration
- Wiring faults
- Heat cycling
- Moisture ingress
Over time, the sensor may lose accuracy or stop functioning altogether.
Symptoms of a Faulty Coolant Level Sensor
Common warning signs include:
- Coolant warning light illuminated
- Intermittent coolant level warnings
- False low coolant alerts
- Warning messages despite correct coolant level
- Cooling system fault codes
- Failure to detect genuine coolant loss
- Dashboard warning messages
In many cases, the sensor may fail before any visible cooling system issues are present.
When Should the Coolant Level Sensor Be Replaced?
Replacement is recommended when:
- False warning messages occur
- Coolant warning lights remain illuminated
- Replacing the coolant expansion tank
- Diagnosing cooling system faults
- Performing preventative maintenance
- Restoring a Porsche 986, 987, 996 or 997
- The original sensor has failed testing
Many specialists replace the sensor during coolant tank replacement as preventative maintenance.
Why Replacement Matters
A properly functioning coolant level sensor provides critical protection for your engine.
Benefits include:
- Accurate coolant level monitoring
- Early warning of coolant loss
- Reduced overheating risk
- Improved engine protection
- Enhanced cooling system reliability
- Prevention of costly repairs
- Improved driver confidence
- Long-term peace of mind
