Radiator Top / Bottom Hoses

Engine Water Coolant Hose, Feed.

Maintain reliable coolant circulation and effective engine temperature control with this Porsche Engine Water Coolant Feed Hose, part number 95B122101A. Designed for compatible Porsche applications, this hose forms part of the engine cooling circuit and carries coolant between the relevant cooling-system components.

Fits:

• Porsche 95B.1 Macan Petrol 2.0L (237Bhp) 2014-18
• Porsche 95B.2 Macan Petrol 2.0L (245Bhp) 2019-21

Cooling-system hoses must safely contain hot, pressurised coolant while tolerating constant temperature changes, engine vibration and movement. Over time, rubber and reinforced hose materials can harden, soften, swell or develop cracks, while connections and sealing areas can also deteriorate.

A damaged coolant feed hose can cause anything from a small intermittent leak to rapid coolant loss. Insufficient coolant can quickly result in overheating, making deteriorated cooling hoses important preventative-maintenance items as vehicles age.

Replacing a worn or leaking hose with the correct Porsche Coolant Feed Hose 95B122101A helps restore a secure cooling circuit and dependable coolant flow.

What This Product Does:

• Carries engine coolant through the cooling system.
• Forms part of the coolant feed circuit.
• Provides a sealed connection between
• associated cooling-system components.
• Contains coolant while the system is hot and pressurised.
• Allows coolant to circulate as intended.
• Helps transfer heat away from the engine.
• Supports stable engine operating temperatures.
• Accommodates normal engine movement and vibration.
• Helps prevent coolant loss.
• Supports efficient radiator and cooling-system operation.
• Helps protect the engine against overheating.
• Replaces a cracked, swollen, leaking or deteriorated coolant hose.
• Provides a Porsche replacement component for compatible applications.  

Symptoms Of Wear Or Failure:

• Visible coolant leakage.
• Coolant level repeatedly dropping.
• Low coolant warning.
• Engine temperature higher than normal.
• Engine overheating.
• Temperature fluctuations.
• Coolant smell from the engine compartment.
• Steam from the engine bay.
• Wetness around the hose or connections.
• Dried or crystallised coolant residue.
• Cracks in the hose surface.
• Bulging or swelling.
• Hose becoming unusually soft.
• Hose becoming hard or brittle.
• Splitting around connection points.
• Damaged or deteriorated hose ends.
• Leakage that becomes more noticeable when the engine is hot.
• Coolant collecting beneath the vehicle.  

Why Replacement Matters:

• The engine cooling system relies on maintaining the correct quantity of coolant and circulating it through a sealed system.
• A deteriorated feed hose can gradually lose coolant or fail suddenly. If enough coolant is lost, the cooling system may no longer be able to control engine temperature effectively.
• Replacing a deteriorated Porsche Coolant Hose 95B122101A before complete failure can therefore prevent a relatively straightforward cooling-system repair from developing into a much more expensive engine problem.

Engine Water Coolant Hose, Feed.

Maintain reliable coolant circulation and effective engine temperature control with this OE Match Engine Water Coolant Feed Hose. Designed for compatible Porsche applications, this hose forms part of the engine cooling circuit and carries coolant between the relevant cooling-system components.  

Fits:

• Porsche 95B.1 Macan Petrol 2.0L (237Bhp) 2014-18
• Porsche 95B.2 Macan Petrol 2.0L (245Bhp) 2019-21

The engine cooling system operates under significant heat and pressure. Coolant hoses must remain flexible enough to accommodate engine movement and thermal expansion while also maintaining a secure, leak-free connection.

Over time, repeated heating and cooling cycles can cause coolant hoses to harden, soften, swell or crack. Connection points and sealing surfaces can also deteriorate, potentially allowing coolant to escape.

Even a relatively small coolant leak can eventually reduce the system level enough to compromise engine cooling. Replacing a deteriorated hose with this OE Match Coolant Feed Hose helps restore a secure coolant circuit and dependable engine temperature management.

What This Product Does:

• Carries coolant through the engine cooling system.
• Forms part of the coolant feed circuit.
• Provides a sealed connection between associated cooling components.
• Contains hot, pressurised engine coolant.
• Supports continuous coolant circulation.
• Helps transfer heat away from the engine.
• Supports stable engine operating temperatures.
• Accommodates normal engine movement and vibration.
• Helps prevent coolant loss.
• Supports efficient cooling-system operation.
• Helps protect the engine against overheating.
• Replaces a cracked, swollen, leaking or deteriorated hose.
• Provides an OE Match replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Visible coolant leakage.
• Coolant level repeatedly dropping.
• Low coolant warning.
• Engine running hotter than normal.
• Engine overheating.
• Unusual temperature fluctuations.
• Coolant smell from the engine compartment.
• Steam from the engine bay.
• Wetness around the hose or its connections.
• Dried or crystallised coolant deposits.
• Cracks in the hose surface.
• Splitting around the hose ends.
• Bulging or swelling.
• Hose becoming unusually soft.
• Hose becoming hard or brittle.
• Damaged connection points.
• Leakage appearing primarily when the engine is hot.
• Coolant collecting underneath the vehicle.  

Why Replacement Matters:

• The cooling system must maintain the correct coolant quantity and circulate it efficiently to control engine temperature.
• A deteriorated coolant hose can cause gradual leakage or, in severe cases, fail suddenly and release a substantial amount of coolant.
• Replacing a deteriorated OE Match Coolant Feed Hose before complete failure can help prevent overheating and considerably more expensive engine repairs.
