How to Replace a Toyota Distributor Cap

How to Replace a Toyota Distributor Cap

The distributor cap on a Toyota is the plastic cap on top of the distributor where the spark plug wires connect. A small plastic rotor spins inside the distributor cap, firing each spark plug as it rotates. A cracked or damaged distributor can cause poor engine performance, so you should replace it immediately. If you are replacing the distributor cap as part of an engine tuneup, you must replace the rotor as well.
