How Do I Replace Engine Oil Cooler Lines?
I have a Ford F-Series Super Duty that I’ve noticed has been leaking coolant lately. Is this a problem with the engine cooler lines, and if so, how can I replace them?

You’re right to look to your engine cooler lines as the source of the problem since coolant leaks are a tell-tale sign that an oil line may need replacing.
If you’re not car-savvy, replacing the engine oil cooler lines yourself could prove difficult—there’s a lot of elbow grease involved in the process. If you’re unsure, it’s always best to bring your car to a mechanic for help.
If you feel ready and able to tackle replacing your engine oil cooler lines yourself, here’s a list of what you’ll need:
- Jack stands
- Hydraulic jack
- Drain pan
- Wrench set
- Socket set
- Screwdriver set
- Wheel chocks
- A couple of towels or rags
You’ll start by setting up your jack stands and wheel chocks, then jacking the vehicle up. From there, you’ll want to locate the faulty oil cooler line (make sure to keep your drain pan close at hand when you disconnect the line, to catch any spilled oil).
You’ll want to remove the lines from the engine entirely, which may involve removing support brackets, clamps, nuts, bolts, and other components. Once they’re disconnected, you can drain them and set them aside. Before installing your new lines, make sure the seals are installed (if not, you’ll want to do that yourself).
From there, you can hook up the new lines in the same way you disconnected connected the old ones, reinstall any necessary support brackets, and you’re ready to go!
As a final test, you can check your engine oil levels before and after starting the vehicle.
Whether you’re paying for the labor of a mechanic or the materials you need to fix it yourself, car maintenance can get expensive. That’s why
