What is radiator top hose replacement?
A cracked or swollen top hose is replaced before it bursts and causes overheating.
The top hose carries hot coolant from the engine to the radiator. Heat makes rubber hard, cracked or soft over time.
Signs you need it
- Coolant leak at the top of the radiator
- Hose feels soft or swollen
- Visible cracks
- Overheating
How it works
- Drain some coolant
- Replace the hose and clamps
- Refill and bleed
- Check for leaks
You can choose a workshop visit or have a professional come to your home, work or depot.
