What is oil cooler replacement?
A leaking oil cooler is replaced to stop oil and coolant mixing or leaking.
Many engines use an oil cooler to control oil temperature. When its seals or core fail, oil can leak out or mix with coolant.
Signs you need it
- Oil in the coolant or coolant in the oil
- Oil leak near the oil filter
- Oil temperature warnings
How it works
- Diagnose the leak
- Replace the oil cooler and seals

- Refill and test
You can choose a workshop visit or have a professional come to your home, work or depot.
