Centre radiator water coolant fluid.



Fits:
Porsche 986 Boxster 3.2L 2000-04
Porsche 996 C2 / C4 / C4S / GT3 1998-05

Radiator fluid, or coolant, is the most important part of your car's cooling system, which protects your engine from overheating. Low coolant can lead to a breakdown and expensive repairs.

The centre radiator acts as extra cooling on some Porsche's also acts as the transmission cooling on other's.

Engine radiator.
A high-quality replacement radiator manufactured to closely match Porsche’s original equipment specification. It serves as a coolant heat exchanger that helps maintain proper engine operating temperature by transferring heat from the engine’s coolant to the surrounding air.

Fits:
Porsche 981 Boxster 2012 - 2016
Porsche 981SP Boxster Spyder 2016
Porsche 981C Cayman 2013 - 2016
Porsche 981C Cayman GT4 2016
Porsche 991.1 Carrera 2012 - 2016

Diagram ref no 1

The radiator circulates hot engine coolant through its cooling fins and tubes, allowing excess heat to dissipate into the air as it passes through. This cooling process keeps the engine within its optimal temperature range, preventing overheating and helping sustain performance, efficiency, and long-term reliability - especially under high-load driving conditions.

Function:
• Uses a network of tubes and fins to transfer heat from coolant to ambient air
• Works with the engine cooling fan and shroud to enhance airflow
•  Helps maintain consistent operating temperature for the engine and drivetrain
•  Supports optimal combustion, performance, and durability, particularly during spirited driving or hot weather

A functional radiator is essential to engine health and performance. Over time, radiators can suffer from:
•   Clogging or corrosion
•   Leaks or cracks
•   Reduced cooling efficiency
•   Coolant contamination.
A failing radiator may lead to overheating, reduced performance, and potential engine damage. Replacing a worn unit with a new radiator ensures proper cooling performance and helps maintain your Porsche’s original thermal management efficiency.

Replace the radiator if you notice:
•   Coolant leaks or visible damage
•   Overheating or fluctuating temperature gauge readings
•   Coolant contamination or debris buildup
•   During engine cooling system overhaul or when other related components are replaced

Radiator fluid, or coolant, is the most important part of your car's cooling system, which protects your engine from overheating. Low coolant can lead to a breakdown and expensive repairs.

Fits:
Porsche 981 Boxster 2012 - 2016
Porsche 981SP Boxster Spyder 2016

Porsche 981C Cayman GT4 2016
Porsche 991.1 Carrera 2012 - 2016

Diagram ref no 1

The radiator functions as the primary heat exchanger in the vehicle’s cooling system. Coolant heated by the engine flows through the radiator’s tubes and fins, where it relinquishes heat to the surrounding air as it passes through. This heat transfer process is essential to prevent overheating, maintain ideal combustion conditions, protect internal engine components, and ensure consistent performance.

Function:
• Dissipates thermal energy from engine coolant via a network of tubes and cooling fins
• Works with the cooling fan and shroud assembly to optimise airflow and cooling efficiency
• Maintains stable engine operating temperatures under varying load and ambient conditions
• Ensures long-term reliability and protects the engine from heat-related wear or damage.

 Genuine Porsche radiators are constructed from durable materials designed to withstand constant temperature changes, road vibration, and corrosion, ensuring sustained performance over time.

Diagram Ref No 23  

Although small, this rubber mounting bush plays an important role in stabilising the radiator assembly while absorbing vibration and movement generated by the engine, road surface and cooling fans.

What This Radiator Mounting Bush Does

The lower radiator mounting bush sits between the radiator and the chassis mounting point. It helps secure the radiator in place while isolating vibration.

This component helps:

• Secure the radiator within the cooling system frame
• Absorb vibration and movement from the engine and road
• Prevent stress damage to the radiator housing
• Maintain proper radiator alignment with cooling ducts and fans

Without these bushes functioning correctly, the radiator may move excessively, leading to premature wear or cooling system issues.

Why Radiator Mounting Bushes Fail

Over time, rubber components within the engine bay are exposed to heat, moisture and road debris. This can cause the bush material to deteriorate.

Common causes of failure include:

Heat degradation
Continuous exposure to engine bay temperatures can cause rubber to harden and crack.

Compression fatigue
Years of supporting the radiator weight can flatten or weaken the bush.

Oil and coolant contamination
Exposure to fluids may accelerate rubber deterioration.

General ageing
Rubber components naturally degrade over time and lose elasticity.

Symptoms of a Worn Radiator Mount Bush

• Loose or unstable radiator positioning
• Rattling or vibration from the front cooling system area
• Visible cracking or deterioration of the rubber mount
• Radiator sitting lower or misaligned within the mount

Replacing worn mounting bushes restores proper support and reduces unwanted vibration in the cooling system.

Why You May Need to Replace This Part

Protect the Radiator Assembly
A stable radiator prevents stress on coolant connections, hoses and fittings.

Reduce Vibration and Noise
New bushes absorb vibration and prevent rattling from the radiator frame.

Prevent Cooling System Damage
Loose radiators can lead to cracked plastic tanks, hose strain or coolant leaks.

Affordable Preventative Maintenance
Replacing small rubber mounts during cooling system service or radiator replacement helps extend the life of the entire system.
