Manufactured to OE specifications for fit, function and reliability, this 2-pin temperature switch helps maintain correct engine operating temperatures, protects against overheating and ensures efficient cooling system performance. It is an essential replacement item for maintaining the reliability of the vehicle's cooling system.
What This Product Does:
- Monitors coolant temperature within the cooling system.
- Activates the electric radiator cooling fan when required.
- Helps maintain optimum engine operating temperature.
- Prevents excessive heat build-up during low-speed driving or idling.
- Supports efficient cooling system operation.
- Protects the engine from overheating-related damage.
Symptoms Of Wear Or Failure:
- Cooling fan fails to operate when the engine reaches operating temperature.
- Engine temperature rises higher than normal.
- Engine overheating during traffic or idle conditions.
- Cooling fan runs continuously regardless of temperature.
- Inconsistent cooling fan operation.
- Temperature warning light activation.
- Reduced cooling system efficiency.
- Overheating during warm weather or heavy traffic conditions.
Why Replacement Matters:
- The fan temperature switch plays a critical role in controlling cooling fan operation and maintaining stable engine temperatures. Over time, repeated heat cycles, age and electrical wear can affect the switch's ability to accurately detect coolant temperature and activate the fan.
- A failed switch can prevent the cooling fan from operating when needed, significantly increasing the risk of overheating. Excessive engine temperatures can damage gaskets, seals, cooling system components and, in severe cases, major engine components.

• Position on Vehicle: Front engine bay, part of the cooling system; mounted at the front of the engine to exchange engine coolant heat with ambient air.
• Applications: Ideal replacement when the original radiator is corroded, leaking, cracked, clogged, or when upgrading cooling performance for spirited driving, restoration or reliability-focused maintenance.
A properly functioning radiator is vital for managing engine heat, maintaining coolant flow and preventing overheating. A degraded radiator can cause elevated temperatures, coolant loss, reduced performance and potential engine damage. Replacing radiator restores correct cooling capacity, protects your engine and supports long-term performance.
When and why to replace:
• Coolant leaks visible around the radiator or mounting points
• Engine temperature running higher than normal or cooling system unable to maintain stable temp
• Radiator shows corrosion, internal blockage, bent fins or damage
• Upgrading to maintain optimum cooling performance for high-load driving or restoration
• Preventative maintenance on higher-mileage or track-used vehicles

Water Coolant Radiators – Efficient Cooling Performance for Porsche Engines
Water coolant radiators are the heart of your Porsche’s cooling system, responsible for maintaining the perfect balance between performance and engine temperature. These components dissipate heat from the coolant as it passes through the radiator core, ensuring your engine operates at peak efficiency while preventing overheating - whether you’re cruising through city streets or pushing hard on the track.
At Design911, we offer a comprehensive range of genuine and high-quality water coolant radiators for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, Panamera and transaxle cars. Each radiator is precision-engineered to provide efficient heat exchange, corrosion resistance, and a perfect fit, ensuring long-lasting performance and reliability for every driving condition.
What Do Water Coolant Radiators Do?
Radiators are essential to your Porsche’s engine cooling
system. Their primary functions include:
- Transferring
heat from the coolant to the surrounding air.
- Regulating
coolant temperature to prevent engine overheating.
- Supporting
overall thermal balance for performance and emissions efficiency.
- Enhancing reliability by maintaining optimal operating temperatures in all climates.
By efficiently dissipating heat, radiators protect your engine, prevent premature wear, and maintain consistent performance under pressure.
Why Do Radiators Fail?
Despite being built for endurance, radiators experience
constant thermal stress, exposure to pressure, and environmental elements that
can lead to failure. Common causes include:
- Corrosion
or rust due to contaminated or old coolant.
- Leaks
from cracked tanks, damaged cores, or failing seals.
- Blockages
caused by debris or scale build-up inside coolant passages.
- Physical
damage from road debris or stone impacts.
- Coolant contamination from oil or combustion residue.
Symptoms of radiator failure include overheating, coolant loss, visible leaks, or fluctuating temperature readings.
Why Replace a Faulty Radiator?
A damaged or inefficient radiator compromises your Porsche’s cooling system, risking overheating and potential engine damage. Replacing your radiator with a high-quality, manufacturer-standard unit ensures optimal cooling efficiency, reliability, and peace of mind.
Benefits of replacement include:
Restored
cooling efficiency and heat dissipation.
Prevention
of engine overheating and coolant loss.
Enhanced
vehicle performance and fuel economy.
Durable,
corrosion-resistant materials for long service life.
All radiators in our range are designed using premium aluminium cores, precision welds, and reinforced end tanks to ensure excellent cooling capacity, leak prevention, and long-term reliability — perfect for both standard and high-performance Porsche applications.
