Frequently Asked Questions

What does a failed injector cup cause?

A failed injector cup lets fuel into the coolant or coolant into the cylinder, depending on the engine. Either way it needs prompt attention to avoid bigger damage.

How do I know if my injector cup is failing?

Fuel in the coolant, coolant loss, a rough-running cylinder, or a fuel smell in the cooling system are common signs. We test to confirm before opening anything up.

Is this a common diesel problem?

Injector cup or sleeve failures are a known issue on several diesel engines. We have the experience and tooling to do the repair correctly.
