Review FORD Used Distributor 2.3 Grade fits TEMPO 1991

The Ford 515491 distributor is specifically designed for use in 1991 Ford Tempos equipped with the 4-140 2.3-liter engine. This essential automotive component is responsible for supplying spark to the engine's cylinders at the correct time during the combustion process.

This distributor features a robust, durable design with a high-quality, precision-machined housing. It is engineered to meet the stringent specifications of Ford Motor Company and is designed to provide reliable and consistent performance.

The distributor cap, which sits atop the distributor, houses the rotor and the spark plug boots. The cap is designed with a large enough diameter to accommodate the required number of spark plugs and is engineered to provide excellent sealing to prevent the loss of combustion pressure.

The rotor, which is mounted to the distributor shaft, is responsible for distributing the spark to the correct cylinder at the right time. The rotor is designed with a sharp leading edge to ensure a clean spark jump across the spark plug gap.

The distributor also includes a vacuum advance unit, which helps to improve engine performance by advancing the timing of the ignition system under light load conditions. This unit is designed to work seamlessly with the engine's vacuum system to provide optimal performance.

The Ford 515491 distributor is also equipped with a centrifugal advance mechanism, which helps to improve engine performance at higher engine speeds by advancing the ignition timing. This mechanism is designed to work in conjunction with the engine's crankshaft position to provide optimal ignition timing under all operating conditions.

In summary, the Ford 515491 distributor is an essential component for the proper functioning of the ignition system in 1991 Ford Tempos equipped with the 4-140 2.3-liter engine. It is designed with a durable, high-quality housing, a large diameter cap to accommodate the required number of spark plugs, a sharp rotor edge for clean spark jump, a vacuum advance unit to improve performance under light load conditions, and a centrifugal advance mechanism to improve performance at higher engine speeds.

Buying a Ford 515491 distributor for a 1991 Tempo with a 2.3-liter engine can be a viable solution if you're experiencing issues with the ignition system. Here are some potential pros and cons to consider before making a purchase:

1. OEM (Original Equipment Manufacturer) part: This distributor is a factory-original replacement, which means it is designed to fit and function exactly like the one that came with your car originally.

2. Improved performance: A new distributor can lead to improved engine performance as it ensures consistent and reliable spark delivery to the engine.

3. Longer lifespan: A new distributor should last longer than a worn-out or failing one, providing better reliability and reducing the need for future repairs.

1. Cost: Replacing a distributor with an OEM part can be more expensive than using aftermarket alternatives, but the cost may be worth it for the peace of mind and improved performance.

2. Installation time: Installing a new distributor can be a time-consuming process, especially if you're not experienced with car repairs. You may need to remove various components to access the distributor and then reassemble everything once it's been replaced.

3. Potential for other issues: If the distributor is not the root cause of your engine performance issues, replacing it may not solve the problem. Other components, such as spark plugs, ignition coils, or even the engine itself, could be the culprit.

A new Ford 515491 distributor for a 1991 Tempo with a 2.3-liter engine can be a worthwhile investment if you're experiencing ignition system issues. While it comes with a higher cost and installation time compared to aftermarket alternatives, the peace of mind and improved performance that come with an OEM part may be worth the expense. However, it's important to consider that other components could be causing your engine performance issues, so it's a good idea to have a thorough diagnosis performed by a professional mechanic before making a purchase.

If you're confident in your ability to install the distributor yourself or have a trusted mechanic to do it for you, and you're certain that the distributor is the root cause of your engine issues, then purchasing the Ford 515491 distributor for your 1991 Tempo with a 2.3-liter engine is a solid choice. If you're unsure, it's recommended that you have a professional mechanic perform a thorough diagnosis to determine the cause of your engine performance issues before making a purchase.
