Tell me about my Radiator Top Hose Replacement
The radiator top hose (also called the upper radiator hose) carries hot coolant from the engine into the radiator for cooling. Over time, the hose can crack, split, or swell due to heat and pressure, leading to leaks and overheating. Replacing a damaged top hose ensures proper coolant flow and protects the engine from overheating damage.
What is a radiator top hose replacement?
This service involves removing the old or leaking upper radiator hose and fitting a new one. The cooling system is then refilled with coolant and bled to remove any trapped air, ensuring efficient cooling performance.
Why do you need a radiator top hose replacement?
A damaged or leaking top hose can cause coolant loss, overheating, and serious engine problems such as a blown head gasket. Replacing the hose restores the correct flow of coolant and keeps your engine operating safely.
Common signs you need a radiator top hose replacement
- Coolant leaking near the top of the radiator or engine
- Engine overheating or running hotter than usual
- Low coolant levels despite topping up
- Visible cracks, bulges, or soft spots on the hose
- Steam from under the bonnet
What happens during a radiator top hose replacement?
A mechanic will:
- Inspect the radiator hoses and cooling system
- Drain some or all of the coolant from the system
- Remove the faulty top hose and clamps
- Install a new, manufacturer-approved hose
- Reconnect clamps securely
- Refill with fresh coolant
- Bleed air from the cooling system
- Run the engine to confirm proper cooling and no leaks
How much does a radiator top hose replacement cost?
Replacement typically costs $180–$350, depending on the vehicle. Costs may be higher if additional cooling system components or coolant need replacement.
Is it unsafe to drive with a damaged radiator top hose?
Yes. A cracked or leaking top hose can quickly lead to coolant loss and overheating, which may cause severe engine damage. The vehicle should not be driven until the hose is replaced.
