GENERAL MOTORS CAP, DISTRIBUTOR 105074

General Motors Distributor Cap 105074

Category: Ignition, Tune-up, and Routine Maintenance Parts

Product Description

The General Motors distributor cap 105074 is a critical ignition system component designed for GM-powered sweepers and scrubbers. Often referred to as the distributor cap, this part plays a vital role in engine operation. Its primary function is to receive high-voltage electricity from the ignition coil and precisely distribute it to the ignition wires, delivering the current to each spark plug.  

The spark plugs, in turn, generate the electrical sparks that ignite the fuel within the engine's cylinders. The distributor cap ensures that these sparks occur at precisely the correct moment in the engine's firing order, which is essential for optimal combustion, efficient performance, and minimized emissions. This precise timing contributes to your sweeper or scrubber's smooth and reliable operation.

Frequently Asked Questions

What Does a Distributor Cap Do? 

A distributor cap's primary function is to route the high-voltage electricity from the ignition coil to the correct spark plug in the engine's firing order. This precise spark distribution is essential for proper combustion and engine performance.

How Often Should I Replace My Distributor Cap? 

Distributor caps are worn items and should be inspected periodically, typically as part of a tune-up. Replacement intervals vary depending on the vehicle and driving conditions, but it's often recommended every 50,000-100,000 miles or as recommended in your vehicle's maintenance schedule.

How Can I Tell if My Distributor Cap is Bad?

Common signs of a failing distributor cap include engine misfires, rough idle, loss of power, poor fuel economy, hard starting or no start, backfiring, unusual engine noises, and visible damage to the cap itself.

Can I Replace a Distributor Cap Myself? 

While some mechanically inclined individuals may be able to replace a distributor cap themselves, it's generally recommended to have it done by a qualified mechanic. Proper installation and timing are crucial for correct engine operation, and mistakes can lead to further problems.
