Introducing the Hayden SX-8559 Automatic Transmission Oil Cooler, specifically designed for Oldsmobile 442 and 98 models from the year 1942 to 2004. This high-performance cooler is an essential upgrade for those seeking improved engine efficiency and reliability.

The Hayden SX-8559 is an external oil cooler that bolts onto the front of your vehicle's engine. It utilizes a large, high-capacity aluminum core that increases the cooling surface area, allowing your transmission oil to dissipate heat more effectively. This is particularly important for Oldsmobile 442 and 98 models, which put significant demands on their automatic transmissions due to their high-performance engines.

The cooler comes with a heavy-duty aluminum end tank that features an integrated pressure cap. This design not only provides an airtight seal, ensuring no coolant or oil leaks, but also allows for easy installation and maintenance. The cooler also includes a high-flow, brazed aluminum hose kit, which includes all necessary hoses and fittings for a straightforward installation.

The Hayden SX-8559 is constructed from premium materials to ensure durability and longevity. The aluminum core and end tank are both TIG-welded for maximum strength, while the hose kit is made from reinforced, high-temperature silicone. This cooler is built to withstand the rigors of high-performance driving, making it an excellent choice for Oldsmobile enthusiasts.

Installing the Hayden SX-8559 oil cooler is a straightforward process. It can be installed using the factory mounting points, and no engine modifications are required. The cooler comes with clear, easy-to-follow installation instructions, and Hayden's dedicated technical support team is available to answer any questions or provide guidance.

These include improved engine efficiency, longer transmission life, and reduced operating temperatures. With its high-performance design, durable construction, and easy installation, this cooler is a must-have for any Oldsmobile enthusiast seeking to get the most out of their vehicle.

The Hayden SX-8559 automatic transmission oil cooler is a popular aftermarket upgrade for Oldsmobile 442 models from 1942 to 2004, including the 98 Az. This cooler is designed to improve the performance and longevity of the automatic transmission by keeping the transmission oil at optimal temperatures. Here are some pros and cons of buying this cooler for your Oldsmobile 442:

Pros:

1. Improved Transmission Performance: By keeping the transmission oil cool, the Hayden SX-8559 cooler helps reduce transmission slippage, which results in improved acceleration and overall performance.

1. Size: The Hayden SX-8559 cooler is larger than the stock cooler, which may require some modifications to the cooling system or the use of custom brackets to ensure proper fitment.

2. Additional Maintenance: With an aftermarket cooler comes the added responsibility of maintaining it. Regular checks and fluid changes are necessary to ensure the cooler continues to function properly.

3. Potential for Leaks: As with any modification that involves plumbing, there is a risk of leaks. Proper installation and regular checks can help mitigate this risk.

In conclusion, the Hayden SX-8559 automatic transmission oil cooler offers several advantages for Oldsmobile 442 owners, including improved performance, enhanced durability, and easy installation.
