Common Problems and How to Fix Them
No engine is perfect, and the 7.3 Powerstroke has a few common problems. But don’t worry — most of these problems are easy to fix and don’t cost much. One common issue is the fuel injector pump.
Sometimes, it can wear out after many miles. When this happens, you might notice the engine running rough or not starting well. Replacing the fuel injector pump usually fixes this problem.
Another issue is the turbocharger. Since the turbo helps the engine get more power, if it fails, the engine can lose power or smoke. Many people replace or rebuild the turbocharger when this happens. Luckily, turbo parts are easy to find.
The 7.3 Powerstroke also has a known problem with the head gaskets. These gaskets help keep the engine sealed and stop coolant and oil from mixing. Over time, they might fail, causing leaks or overheating. Fixing this is more serious but still manageable for good mechanics.
Lastly, the glow plugs, which help start the engine in cold weather, sometimes fail. This is normal for diesel engines but can be fixed by changing the glow plugs. Overall, these issues don’t stop the 7.3 Powerstroke from being a good engine, but knowing about them helps you be ready.
- Fuel injector pump may wear out and cause rough running.
- Turbocharger failure can lead to loss of power or smoke.
- Head gasket leaks can cause overheating and need repair.
