Radiator Top / Bottom Hoses
By OE Match
- Porsche 95B.1 Macan Petrol 2.0L (237Bhp) 2014-18
This Water Coolant Bottom Hose (Return) is a precision-engineered OE Match coolant hose designed to replace the factory lower radiator return hose on the Porsche 95B Macan 2.0 L petrol SUV. This hose carries coolant back to the engine after it exits the radiator, completing the primary coolant circulation loop.
Fits:
Porsche 95B.1 Macan 2.0L 2014 - 2018
* Engine codes: CNC,CNCC, CYN,CYNA, CYNB,CYP, CYPA
Porsche 95B.2 Macan 2.0L 2019 - 2021
* PR: T2G / T2G
Porsche 95B.23 Macan 2.0L 2022 >>
* PR: T2G / T2G

The Macan’s 2.0 L turbocharged engine relies on a closed-loop liquid cooling system to maintain stable operating temperatures. While the top coolant hose (feed) delivers hot coolant from the engine to the radiator for heat rejection, the bottom hose (return) completes the cycle by returning cooled fluid back to the engine. Both pathways must be free of restrictions, leaks, and surface deterioration to ensure consistent thermal control.
The bottom coolant return hose:
• Carries cooled coolant back to the engine from the radiator
• Maintains consistent coolant flow and pressure
• Supports stable engine temperature regulation
• Helps prevent overheating and engine stress
Maintaining a healthy return hose is essential for balanced cooling system performance and long-term engine reliability.
Hoses in the cooling system are subject to constant heat cycling, coolant pressure, and mechanical movement. Over time they can:
• Harden or crack
• Soften and swell
• Leak at hose connections
• Restrict coolant flow
A failing return hose can reduce coolant circulation, cause hot spots within the engine, and lead to overheating, coolant loss, or pressure imbalance in the system. Replacing with a new OE Match hose helps restore proper coolant routing and preserves engine health.
Replace this hose if you notice:
• Coolant leaks at the hose ends
• Visible cracks, soft spots, or bulges
• Overheating during normal driving
• Coolant smell from under the vehicle
• During water pump, thermostat, or radiator service
• As preventative maintenance on high-mile vehicles

- Porsche 95B.1 Macan Petrol 2.0L (237Bhp) 2014-18
This Water Coolant Top Hose (Feed) is an OE Match radiator feed hose designed to replace the original upper coolant hose on the Porsche 95B Macan 2.0L. This hose is part of the top-end cooling circuit, directing hot coolant from the engine towards the radiator for heat dissipation.

The top coolant hose plays a vital role in the engine’s thermal management system, carrying coolant between the thermostat outlet and the top connection of the radiator. On turbocharged engines like the 2.0L Macan’s, coolant temperatures and pressure fluctuations can be more extreme, so this hose must meet high standards for durability, temperature resistance, and fluid compatibility.
The water coolant top (feed) hose:
• Transports hot coolant from the engine to the radiator
• Supports stable engine temperature regulation
• Helps prevent overheating during load or high ambient conditions
• Maintains correct coolant pressure and flow
A properly functioning top coolant hose ensures your engine operates within its designed temperature range, protecting internal components from thermal stress and wear.
Coolant hoses degrade over time due to heat cycles, pressure variations, and chemical exposure. A compromised top coolant hose can lead to:
• Coolant leaks at connections or along the hose body
• Reduced coolant flow and elevated engine temperature
• Overheating under load or in high ambient conditions
• Hose swelling, cracking, or collapse.
Replacing aged or damaged hoses with an OE Match part restores proper coolant circulation and helps protect your engine from heat-related failures.
Replace the top coolant hose if you notice:
• Coolant stains or drips around hose ends
• Swollen, soft, cracked, or brittle hose material
• Coolant smell from the engine bay
• Rising temperature gauge under load
• During water pump, thermostat, or radiator service
• Preventative maintenance on ageing vehicles

Radiator top and bottom hoses carry coolant between the engine and the radiator on Porsche models, helping to regulate operating temperature and support reliable running across everyday use and more demanding driving. OEMatch radiator top and bottom hoses are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable.
Available Types- Moulded top hose and shaped bottom hose to match common Porsche coolant routing
- Reinforced rubber and fabric-wrapped constructions for higher temperature or pressure applications
- Complete hose assemblies including integrated fittings where applicable
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original radiator top and bottom hoses. OE (Original Equipment) refers to parts matching original specifications for the radiator top and bottom hoses and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM radiator top and bottom hoses engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Radiator hoses route hot coolant to the radiator and return cooled fluid to the engine; they are formed to fit around intake and accessory components and use clamps or quick-fit fittings to secure connections. OEMatch focuses on radiator top and bottom hose items selected for Porsche applications.
Benefits Include- Restored coolant flow and improved temperature stability
- Reduced risk of leaks and loss of coolant
- Materials chosen for heat resistance and flexibility to cope with engine movement
- Thermal ageing and repeated heat cycles cause rubber to harden and crack
- Chemical degradation from coolant additives can produce soft spots or swelling
- Abrasion, clamp wear or routing contact can lead to local damage and leaks
A failing hose can allow coolant loss and lead to overheating with risk to the engine. Replacing worn hoses maintains cooling circuit pressure and flow, supports stable engine temperature on Porsche models and reduces the chance of roadside breakdown. Fit the correct hose profile and use appropriate clamps or fittings to avoid leaks and ensure a reliable connection.
Advantages- Made to original-spec dimensions where applicable to aid fitment and routing
- Fits original mounting points and clearances to minimise refit work
- Available in multiple constructions to match repair needs and operating conditions
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
