A Quick Look at OE Match
OE Match information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.
Choosing the Right Fit for Your Porsche
Where OE Match is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.
- Often chosen when owners want OE-equivalent quality with sensible running costs, especially for routine service and wear items.
- Typical reasons to replace include restoring reliability, addressing age-related wear, or refreshing multiple components during larger repair work.
- Common defects from incorrect application include noise, premature wear, leaks, or fitment quirks if the wrong variant is selected or fitted with old seals/hardware.
- Watch for symptoms such as unusual noises, early wear, or repeat failures after recent work, which can indicate mismatched parts or supporting items left worn.
- Always cross-check OEM part numbers, read model-year notes, and verify compatibility before ordering.
- For safety-critical components, confirm specification and fitment carefully and have installation checked by a competent technician.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include vibration under braking, longer stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.
Brake Pad Wear Sensors — Brake pad wear sensors are replaced when pads are renewed or when warning lights indicate a broken or worn sensor. Symptoms include brake wear warnings even with new pads, damaged sensor cables, or broken clips around the caliper area.
Engine Electrical — Engine electrical parts are changed when there are starting, charging, ignition, or sensor-related faults that affect drivability and reliability, such as intermittent no-start, misfires, rough idle, poor charging, warning lights or heat-soak failures.
Service Parts — Service parts are replaced as routine maintenance to keep the engine and systems reliable, efficient, and protected, often resolving hard starting, rough idle, poor fuel economy and warning lights caused by clogged filters or worn ignition components.
Service Kits — Service kits bundle key service components to simplify maintenance and set the car back to a known baseline, especially useful when catching up on overdue servicing or dealing with general sluggish running, inconsistent idle and reduced performance.
- For brake parts, confirm whether items are OE-equivalent replacements or performance upgrades and check if new fitting kits and sensors are required.
- On service items and kits, match the kit to your exact Porsche model, engine and year, and review what is included so you can add any extra “while you are there” parts.

Complete Water Pump Kit – Water Pump, Thermostat,
Serpentine Belt & Gaskets for a Full Cooling System Refresh
This complete water pump kit includes a new water
pump, thermostat, drive (serpentine) belt and the required gaskets for both the
pump and thermostat housing.
Fits:
- Porsche 991.1 Carrera C2S 3.8L (400Bhp) 2012-16
- Porsche 991.1 Carrera C4S 3.8L (400Bhp) 2012-16
Designed as a comprehensive cooling system service package, it ensures correct coolant circulation, accurate temperature regulation, and reliable accessory belt operation. Ideal for preventative maintenance or full cooling system repair, this kit provides everything needed to restore confidence in your Porsche’s engine cooling performance.
The water pump continuously circulates coolant through the engine and radiators, while the thermostat regulates operating temperature and ensures the engine warms up properly. The serpentine belt drives essential accessories—including the water pump—so replacing all these components together ensures long-term reliability and prevents future breakdowns.
What This Complete Water Pump Kit Does
This cooling system service kit:
- Replaces
the water pump to restore proper coolant flow
- Includes
a new thermostat for accurate temperature control
- Supplies
a fresh serpentine belt to ensure reliable accessory drive operation
- Comes
with all required gaskets to prevent leaks during installation
- Improves
cooling efficiency, reducing the risk of overheating
- Ensures long-term reliability with coordinated component replacement
- Perfect for workshop servicing, DIY maintenance or high-mileage cooling system refreshes.
Why Water Pumps, Thermostats & Belts Fail
Common failure points include:
- Bearing
wear inside the water pump, causing leaks or noise
- Impeller
degradation, reducing coolant flow
- Thermostat
sticking, leading to overheating or overcooling
- Serpentine
belt cracking, glazing or stretching
- Coolant
contamination, accelerating component wear
- Heat cycling, which weakens gaskets and housings
Cooling failures can cause warped cylinder heads, engine misfires or complete engine failure if not addressed promptly.
Why These Components Should Be Replaced Together
Replacing the pump, thermostat and serpentine belt as a set
ensures:
- Restored cooling performance across the entire system
- Correct belt tension and accessory drive function
- Reduced labour costs by avoiding repeat disassembly
- Balanced
longevity, as all components age similarly
- Prevention
of leaks, thanks to new gaskets and seals
- Peace of mind for daily driving, long trips or track use

What This Product Does:
- The indicator lens serves as the transparent/amber cover for the front turn-signal / parking-/blinker light. It protects the bulb and reflector inside the indicator housing while providing the correct optical characteristics to meet visibility and regulation requirements.
- The optical lens surface (molded pattern, curvature, amber/clear colouring) ensures the light is diffused and visible to other road users when the indicator flashes — which is crucial for signalling direction changes, lane changes, or turns.
- The chrome rim around the lens provides a correct-period aesthetic finish, preserving the classic look of the early 911 / 912 cars.
- Cracks, chips, or breaks — due to age, stone chips, minor collisions or weathering. A damaged lens can leak water or dust into the housing, damaging the reflector or bulb.
- Fading or discoloration — old lenses often yellow or cloud over time, reducing light output and visibility.
- Loose or missing chrome rim / seal — can lead to poor sealing, moisture ingress, or misalignment.
- Non-compliant appearance or failed inspection — a cracked or broken lens may fail a vehicle inspection or be illegal to drive with, depending on local laws.
- Restoration or authenticity: for classic car restoration, correct lenses maintain vintage originality and value.
- Safety & legality: Working, undamaged indicators are essential for signalling — cracked or faded lenses reduce visibility and may lead to accidents or fail legal inspections.
- Protection of internal components: A proper lens seals out water, dust, and debris — protecting the reflector and bulb, and preventing corrosion or electrical issues.
- Maintaining classic appearance & value: For vintage cars like 911/912 (1965–73), original-style lens and chrome rim contribute heavily to authenticity and market value.
- Performance and visibility: Clear, properly coloured lenses ensure that your signals are bright and visible to other drivers.

Crankcase Breather System (Air/Oil Separator)
The crankcase breather system, also known as the air/oil separator (AOS), is a critical engine component that should be replaced every 30,000 miles—or sooner if signs of failure appear.
When the system fails, it can cause:
- Vacuum leaks due to cracked hoses or a damaged air/oil separator
- Oil consumption and fouled spark plugs, as oil is drawn into the intake
- Increased crankcase pressure, which can lead to gasket leaks and other engine issues
Preventative Maintenance
Preventative maintenance is always the best approach. Our comprehensive Crankcase Breather Hose Kit includes all the components you need to replace the system properly. We also recommend performing an engine oil change at the same time to ensure peak performance and longevity.

The AOS is basically a small diaphragm distillery which distills the minute amounts of oil mist in the crankcase, liquifies it and sends it back to the crankcase. The "clean" air is now sent into the air intake (after the throttle body) to be burned off by the engine.
When the AOS starts to fail it cannot separate all of the oil out of the mist and some liquid oil is sent to the air intake.
A few drops of oil is enough to generate the GREAT SMOKE BOMB for which our cars are famous for.
A big smoke bomb once in a while is completely normal, due to the architecture of the flat-6 engine, which may let a drop of oil flow into one of the combustion chambers sporadically.

This kit is comprised of the following items:
- Porsche 958 Cayenne S V6 3.0L Hybrid 380HP 2010-17
Designed to manage engine temperature under all driving conditions, these components circulate coolant through the engine, radiator, and heat-exchanger system. They help maintain optimal operating temperature, protect the engine from overheating, and prevent corrosion inside the coolant system.

Diagram Ref No 11 And 12
What This Product Does:
- Regulates engine temperature by circulating coolant efficiently
- Transfers heat from the engine to the radiator for cooling
- Maintains correct pressure and flow within the coolant circuit
- Prevents overheating during heavy load, towing, or hot climates
- Prevents coolant boiling or freezing depending on environment
- Protects engine components from corrosion and scale build-up
Symptoms Of Failing Radiator / Coolant Cooler:
- Engine overheating or fluctuating temperature
- Coolant leaks under the front of the vehicle
- Low coolant level requiring frequent top-ups
- Visible cracks, corrosion, or damaged coolant lines
- Radiator fans running excessively
- Poor cabin heating (on some models)
- Strong coolant smell from the engine bay
- Sludge or discolouration in the coolant tank
- Dashboard coolant warnings or overheating messages
Why Replacement Matters:
- Overheating is one of the fastest ways to cause catastrophic engine failure. Proper cooling system components prevent this.
- Fresh components and healthy coolant protect aluminium radiators, water pumps, thermostat housings, and engine passages.
- Engines run best at optimal temperature. A failing cooling system reduces power and efficiency.
- Replacing a coolant cooler/radiator component is far cheaper than repairing warped heads, blown head gaskets, or damaged cylinder banks.
- Hybrid Cayenne models rely heavily on coolant circulation for both engine and electrical system thermal management.
