Review HAYDEN Engine Oil Cooler Plymouth Custom Zo fits BELVEDERE FURY PLAZA 1955–1959

The Hayden SX-20PM Engine Oil Cooler is an essential upgrade for the classic 1955-1959 Plymouth Belvedere, Fury, Plaza, and Zodiac models. This high-performance cooler is designed to improve engine reliability and longevity by effectively reducing engine oil temperatures.

The SX-20PM is a parallel flow, pressure tested, and brazed aluminum cooler. Its compact size, measuring 11 inches long, 7 inches wide, and 3 inches thick, makes it a perfect fit for the limited space available in these classic vehicles. The cooler features a durable powder-coated finish that not only looks great but also provides excellent protection against corrosion and the elements.

This engine oil cooler uses a high-density, pressed-aluminum core with a large surface area for maximum cooling efficiency. The cooler comes with a brass oil inlet and outlet, which are threaded for 1/8 NPT fittings. Additionally, it includes an oil temperature sender that is compatible with most aftermarket oil temperature gauges.

The Hayden SX-20PM cooler utilizes an external fan for efficient cooling. The fan is a 12-volt, thermostatically controlled unit that kicks on when the engine oil temperature reaches a predetermined threshold. This ensures optimal engine oil cooling when it is needed most, maintaining the ideal operating temperature for the engine.

Installing the Hayden SX-20PM Engine Oil Cooler is a straightforward process. It comes with all necessary mounting hardware, including brackets for easy installation on the vehicle's engine. The cooler can be positioned horizontally or vertically, depending on the available space and cooling requirements.

Investing in a Hayden SX-20PM Engine Oil Cooler for your 1955-1959 Plymouth Belvedere, Fury, Plaza, or Zodiac not only enhances its performance but also adds an element of customization to this classic vehicle. With its superior cooling capabilities, durability, and easy installation, this engine oil cooler is an excellent choice for enthusiasts looking to take their classic Plymouth to the next level.

The Hayden SX-20PM engine oil cooler is a popular aftermarket upgrade for older Plymouth Belvedere, Fury, Plaza, and Zodiac models from 1955 to 1959. This cooler aims to improve engine performance and cooling efficiency. Here are some potential advantages and disadvantages of installing this cooler.

Ending Conclusion:

The Hayden SX-20PM engine oil cooler can offer several advantages, including enhanced cooling, increased engine life, improved power output, and potentially better fuel economy. However, it also comes with some disadvantages, such as cost, complexity, potential for leaks, and possible interference with other components. Ultimately, the decision to install an engine oil cooler on a 1955-1959 Plymouth Belvedere, Fury, Plaza, or Zodiac depends on your budget, technical skills, and desired performance improvements.
