Engine Repair & Tune-Ups in Fullerton

From tune-ups and leaks to major engine work — modern engines and classic V8s.

Quick answer

Cedillo's in Fullerton handles engine repair from tune-ups, ignition and fuel injection work to oil leaks, gaskets and major engine repair, on modern engines and classic V8s. Rafael Cedillo explains the options and the cost before any work begins.

A healthy engine starts with a good tune-up: spark, fuel and air in the right balance. One customer told us Rafael didn't just fix his car's tune — he made it run better than the original setup.

When the problem is bigger — leaks, gaskets, timing components or internal repairs — we explain what we found, what it will take, and what it's worth on your vehicle.

  • Tune-ups, spark plugs & ignition

How do I know my car needs a tune-up?
