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

This kit offers the most reliable and cost-effective approach to cooling system maintenance.

Product Information
Product Information
Keep your Porsche Macan 2.0L running at the correct temperature with this OEM-equivalent engine water pump and thermostat housing assembly. Supplied as a complete module with thermostat, it’s designed as a direct replacement for the factory unit used on the 95B Macan 2.0 from 2015–2018.  

Key Features

  • Complete water pump + thermostat + housing assembly
  • Direct fit for Porsche 95B Macan 2.0L (petrol) 2015–2018
  • Mechanical pump design for reliable coolant circulation
  • Integrated thermostat for precise, factory-spec temperature control
  • OEM cross-reference: PAC121111C / Porsche 95812101200, 95812111100, 95812111110, 95812111111, PAC121111A/B, PAC121012B
  • You can drop this unit straight in place of the original without modification, ideal for both dealer-level and independent workshop repairs.

Why this part should be replaced

  • On the 2.0-litre Macan, the water pump and thermostat housing is a known weak point. Owners and specialists frequently report:
  • Coolant leaks from the pump or the plastic housing seams
  • Cracks or warping in the thermostat housing over time
  • Internal seal failure, allowing coolant to escape
  • Sticking thermostat, causing the engine to run too cold or overheat
  • Because the pump, thermostat and housing are integrated, it’s more cost-effective and reliable to replace the complete assembly rather than just the thermostat or pump alone.

Typical reasons to replace:

  • Visible coolant leak at the front/right-hand side of the engine
  • Repeated “Check coolant level” warnings
  • Engine temperature running higher or lower than normal
  • Overheating in traffic or under load
  • Preventive maintenance when doing major cooling or front-engine work

About Water / Coolant Pumps

Water / Coolant Pumps – Reliable Engine Cooling for Porsche Vehicles

Water / coolant pumps are at the heart of your Porsche’s cooling system. Their job is to circulate coolant through the engine, radiator, and heater core, maintaining the correct operating temperature and preventing overheating. A properly functioning water pump ensures efficient heat transfer, optimal performance, and long-term engine reliability.

At Design911, we supply a wide range of genuine and high-quality water pumps for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, Panamera and the transaxle cars. Each pump is precision-engineered to deliver consistent coolant flow, high durability, and dependable performance - ensuring your Porsche’s engine stays cool under all driving conditions.

What Do Water Coolant Pumps Do?

Water pumps are a critical part of your engine’s temperature control system. They:

  • Circulate coolant between the engine block, radiator, and heater system.
  • Regulate temperature by dispersing heat efficiently throughout the system.
  • Maintain coolant pressure for consistent engine operation.
  • Support performance and longevity, preventing damage from excessive heat.

Without a properly working water pump, coolant circulation stops — leading to overheating, loss of performance, and potential engine failure.

Why Do Water Coolant Pumps Fail?

Even the most durable water pumps can fail over time due to heat, age, and coolant contamination. Common causes of failure include:

  • Bearing wear or seal leaks caused by prolonged use or poor coolant quality.
  • Corrosion or pitting from old or incompatible coolant mixtures.
  • Cracked impellers or worn components reducing flow efficiency.
  • Coolant leaks around the housing or pulley.
  • Age-related wear, especially in high-mileage vehicles.

Signs of failure include visible coolant leaks, high engine temperature, whining noises from the pump area, or reduced cabin heating.

Why Replace a Faulty Water Coolant Pump?

A failing water pump can cause severe engine overheating, loss of coolant, or total breakdown. Replacing a worn pump restores reliable cooling and helps protect your engine from costly damage.

Benefits of replacement include:

  • Restored coolant circulation and cooling efficiency.
  • Improved engine reliability and performance.
  • Prevention of leaks, overheating, and corrosion.
  • Long-lasting, high-quality construction for dependable operation.

All water pumps in this range are built using high-strength materials, precision impellers, and sealed bearings designed to deliver durability, quiet operation, and efficient coolant flow over time.
