Engine radiator. Porsche 981 Boxster / 981C Cayman / 991.1  ❭  99110613

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

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
