What These Radiators Kit Do
The Porsche 718 cooling system relies on three front-mounted radiators to dissipate heat from the engine coolant. These radiators maintain stable engine operating temperatures by transferring heat away from the coolant through airflow across the radiator core.
A properly functioning radiator system helps:
• Prevent engine overheating
• Maintain optimal engine performance
• Protect cylinder heads and gaskets
• Improve cooling during heavy traffic or hot weather
• Support track and performance driving conditions
Why Porsche Radiators Fail
Over time, original radiators can suffer from:
- Road debris damage
- Corrosion and coolant contamination
- Plastic end tank fatigue
- Blocked cooling cores
Replacing all three radiators together ensures balanced cooling performance and prevents repeated labour costs.

Diagram Ref No 7
Modern Porsche engines rely on efficient coolant circulation to maintain safe operating temperatures, especially during spirited driving or extended high-load conditions. A properly functioning coolant hose ensures consistent coolant flow and helps protect the engine from overheating.
What This Coolant Hose Does
The cooling system on the Porsche 718 uses multiple radiators positioned at the front of the vehicle to dissipate heat from the engine coolant. The centre radiator improves cooling efficiency under higher loads.
The left hand coolant hose helps:
• Carry coolant between the
centre radiator and the main cooling circuit
• Maintain stable engine operating temperatures
• Ensure efficient heat dissipation through the radiator system
• Support reliable cooling during fast road or track driving
Without proper coolant flow, engine temperatures can rise quickly, increasing the risk of overheating and engine damage.
Why Coolant Hoses Fail
Coolant hoses operate under constant pressure and high temperature conditions. Over time, materials degrade and may begin to fail.
Common causes of hose failure include:
Heat ageing
Continuous heating and cooling cycles can cause rubber hoses to harden or
crack.
Pressure fatigue
The cooling system operates under pressure, which can weaken older hoses and
cause swelling or splits.
Coolant contamination
Old coolant or contaminants may degrade hose materials internally.
Mechanical wear
Movement, vibration or contact with nearby components can damage the hose over
time.
Symptoms of a Failing Coolant Hose
• Visible coolant leaks under
the vehicle
• Sweet coolant smell from the front of the car
• Low coolant warning messages
• Engine temperature rising unexpectedly
• Visible cracking, swelling or soft spots on the hose
Replacing worn hoses prevents sudden coolant loss and protects the engine from overheating.
Why You May Need to Replace This Hose
Prevent Cooling System Leaks
Replacing ageing hoses ensures the cooling system remains properly sealed and
pressurised.
Maintain Engine Cooling
Performance
Reliable coolant flow is essential for maintaining correct operating
temperatures in high performance engines.
Protect Engine Components
Coolant loss can lead to overheating, which may cause severe engine damage if
left unresolved.

Modern Porsche engines rely on efficient coolant circulation to maintain safe operating temperatures, especially during spirited driving or extended high-load conditions. A properly functioning coolant hose ensures consistent coolant flow and helps protect the engine from overheating.
What This Coolant Hose Does
The cooling system on the Porsche 718 uses multiple radiators positioned at the front of the vehicle to dissipate heat from the engine coolant. The centre radiator improves cooling efficiency under higher loads.
The left hand coolant hose helps:
• Carry coolant between the
centre radiator and the main cooling circuit
• Maintain stable engine operating temperatures
• Ensure efficient heat dissipation through the radiator system
• Support reliable cooling during fast road or track driving
Without proper coolant flow, engine temperatures can rise quickly, increasing the risk of overheating and engine damage.
Why Coolant Hoses Fail
Coolant hoses operate under constant pressure and high temperature conditions. Over time, materials degrade and may begin to fail.
Common causes of hose failure include:
Heat ageing
Continuous heating and cooling cycles can cause rubber hoses to harden or
crack.
Pressure fatigue
The cooling system operates under pressure, which can weaken older hoses and
cause swelling or splits.
Coolant contamination
Old coolant or contaminants may degrade hose materials internally.
Mechanical wear
Movement, vibration or contact with nearby components can damage the hose over
time.
Symptoms of a Failing Coolant Hose
• Visible coolant leaks under
the vehicle
• Sweet coolant smell from the front of the car
• Low coolant warning messages
• Engine temperature rising unexpectedly
• Visible cracking, swelling or soft spots on the hose
Replacing worn hoses prevents sudden coolant loss and protects the engine from overheating.
Why You May Need to Replace This Hose
Prevent Cooling System Leaks
Replacing ageing hoses ensures the cooling system remains properly sealed and
pressurised.
Maintain Engine Cooling
Performance
Reliable coolant flow is essential for maintaining correct operating
temperatures in high performance engines.
Protect Engine Components
Coolant loss can lead to overheating, which may cause severe engine damage if
left unresolved.

Diagram Ref No 23
Although small, this rubber mounting bush plays an important role in stabilising the radiator assembly while absorbing vibration and movement generated by the engine, road surface and cooling fans.
What This Radiator Mounting Bush Does
The lower radiator mounting bush sits between the radiator and the chassis mounting point. It helps secure the radiator in place while isolating vibration.
This component helps:
• Secure the radiator within the cooling system frame
• Absorb vibration and movement from the engine and road
• Prevent stress damage to the radiator housing
• Maintain proper radiator alignment with cooling ducts and fans
Without these bushes functioning correctly, the radiator may move excessively, leading to premature wear or cooling system issues.
Why Radiator Mounting Bushes Fail
Over time, rubber components within the engine bay are exposed to heat, moisture and road debris. This can cause the bush material to deteriorate.
Common causes of failure include:
Heat degradation
Continuous exposure to engine bay temperatures can cause rubber to harden and
crack.
Compression fatigue
Years of supporting the radiator weight can flatten or weaken the bush.
Oil and coolant contamination
Exposure to fluids may accelerate rubber deterioration.
General ageing
Rubber components naturally degrade over time and lose elasticity.
Symptoms of a Worn Radiator Mount Bush
• Loose or unstable radiator positioning
• Rattling or vibration from the front cooling system area
• Visible cracking or deterioration of the rubber mount
• Radiator sitting lower or misaligned within the mount
Replacing worn mounting bushes restores proper support and reduces unwanted vibration in the cooling system.
Why You May Need to Replace This Part
Protect the Radiator Assembly
A stable radiator prevents stress on coolant connections, hoses and fittings.
Reduce Vibration and Noise
New bushes absorb vibration and prevent rattling from the radiator frame.
Prevent Cooling System Damage
Loose radiators can lead to cracked plastic tanks, hose strain or coolant
leaks.
Affordable Preventative Maintenance
Replacing small rubber mounts during cooling system service or radiator
replacement helps extend the life of the entire system.

Although small, this rubber mounting bush plays an important role in stabilising the radiator assembly while absorbing vibration and movement generated by the engine, road surface and cooling fans.
What This Radiator Mounting Bush Does
The upper radiator mounting bush sits between the radiator and the chassis mounting point. It helps secure the radiator in place while isolating vibration.
This component helps:
• Secure the radiator within the cooling system frame
• Absorb vibration and movement from the engine and road
• Prevent stress damage to the radiator housing
• Maintain proper radiator alignment with cooling ducts and fans
Without these bushes functioning correctly, the radiator may move excessively, leading to premature wear or cooling system issues.
Why Radiator Mounting Bushes Fail
Over time, rubber components within the engine bay are exposed to heat, moisture and road debris. This can cause the bush material to deteriorate.
Common causes of failure include:
Heat degradation
Continuous exposure to engine bay temperatures can cause rubber to harden and
crack.
Compression fatigue
Years of supporting the radiator weight can flatten or weaken the bush.
Oil and coolant contamination
Exposure to fluids may accelerate rubber deterioration.
General ageing
Rubber components naturally degrade over time and lose elasticity.
Symptoms of a Worn Radiator Mount Bush
• Loose or unstable radiator positioning
• Rattling or vibration from the front cooling system area
• Visible cracking or deterioration of the rubber mount
• Radiator sitting lower or misaligned within the mount
Replacing worn mounting bushes restores proper support and reduces unwanted vibration in the cooling system.
Why You May Need to Replace This Part
Protect the Radiator Assembly
A stable radiator prevents stress on coolant connections, hoses and fittings.
Reduce Vibration and Noise
New bushes absorb vibration and prevent rattling from the radiator frame.
Prevent Cooling System Damage
Loose radiators can lead to cracked plastic tanks, hose strain or coolant
leaks.
Affordable Preventative Maintenance
Replacing small rubber mounts during cooling system service or radiator
replacement helps extend the life of the entire system.
