Custom Search


In this and the next page we will illustrate how to replace the timing belt on 1993-1997 Geo Prizm. The vehicle we are working on is a 1995 Geo Prizm equipped with a 1.6L engine, the engine code is 4A-FE, this is a Toyota engine, it can also be found on 1993-1997 Toyota Corolla.

Even though this engine is a DOHC design, when we went to buy the timing belt component kit at the parts store they showed it as SOHC because it only has one camshaft sprocket, the second camshaft is gear driven by the first camshaft.  Pay attention when buying the timing belt for your car, if your vehicle has 2 camshaft sprockets the steps on this page won't apply.
