Buy Oldsmobile Cutlass Distributor Cap Covers

A distributor cap cover is a crucial component in the ignition system of older vehicles equipped with a distributor-based ignition. Also known as a distributor cover or ignition distributor cap, it protects the internal parts of the distributor from external contaminants like dust, moisture, and debris. The distributor cap cover ensures that the electrical current is properly directed from the ignition coil to the spark plugs in the correct firing order, which is essential for engine performance and efficiency.

Over time, distributor cap covers can wear out or become damaged due to constant exposure to high voltage and environmental factors. Common issues include:

Cracks or Corrosion: Physical cracks or corrosion inside the cap can lead to misfires or engine hesitation.
Carbon Tracking: This is a buildup of carbon deposits inside the cap, which can create a misfire condition.
Moisture Intrusion: Water or moisture entering the cap can cause poor engine performance or failure to start.
Wear and Tear: The contacts inside the cap can wear down, leading to ineffective voltage transfer to the spark plugs.

Signs that the distributor cap cover may need replacement include:

Engine Misfires: Inconsistent firing of spark plugs causing rough running or stalling.
Difficulty Starting: Hard starting or failure to start due to inadequate spark delivery.
Reduced Engine Performance: Noticeable loss of power or acceleration.
Unusual Noises: Squealing or tapping sounds coming from the distributor area.

Regular inspection and maintenance of the distributor cap cover can prolong its life and ensure optimal engine performance:

Routine Inspections: Check the cap for cracks, burns, or corrosion during regular vehicle maintenance.
Clean Contacts: Keep the internal contacts clean from carbon buildup using appropriate cleaning agents.
Moisture Control: Ensure the cap is properly sealed to prevent moisture entry, especially in wet climates.
Timely Replacement: Replace the cap according to the vehicle manufacturer's recommended intervals or when signs of wear are evident.

When installing a new distributor cap cover, consider the following to ensure proper function:

Label Wires: Before removal, label all spark plug wires to maintain the correct firing order upon reinstallation.
Inspect Rotor: Check the distributor rotor for wear and replace it if necessary when replacing the cap.
Secure Fit: Ensure the cap is seated correctly and secured tightly to prevent vibrations or loosening.
Dielectric Grease: Apply a small amount of dielectric grease to the contacts to improve conductivity and prevent corrosion.
