Effortless Steps to Revive Your Rusted Swamp Cooler in 5 Easy Ways

Swamp coolers, also known as evaporative coolers, are a popular and cost-effective way to cool homes, especially in dry climates. However, over time, these coolers can become susceptible to rust, which can lead to leaks, reduced efficiency, and even complete failure. In this comprehensive guide, we’ll walk you through the step-by-step process of fixing a rusted swamp cooler, ensuring it operates at its best for years to come.

Prepare the Pan

The first step in repairing a rusted swamp cooler is to thoroughly clean the pan. Begin by removing any silicone sealant used to patch the pan. Use a utility knife or a razor blade to carefully scrape off the sealant, taking care not to damage the underlying metal. Next, use a cordless pressure washer or a high-pressure nozzle on a garden hose to clean the pan thoroughly, removing any dirt, debris, or loose rust. Allow the pan to dry completely before proceeding to the next step.

Scrape Loose Paint and Rust

Once the pan is clean and dry, it’s time to remove any loose paint and rust. Use a hand scraper, a cordless oscillating multitool with a scraper blade, sandpaper, or a wire brush to carefully remove the loose material. Be sure to work in a well-ventilated area and wear appropriate personal protective equipment (PPE), such as safety glasses, gloves, and a mask, to prevent exposure to any harmful particles.

Apply Paint

After removing the loose paint and rust, it’s time to apply a fresh coat of paint to the interior of the cooler. Use a quality interior/exterior spray paint that is specifically designed for metal surfaces. Apply the paint in thin, even coats, allowing each coat to dry completely before applying the next. Typically, two to three coats will provide adequate coverage and protection.

Apply Patch & Seal Tape

Inspect the pan for any holes or cracks, and use Gorilla Waterproof Patch & Seal Tape to cover them. This tape is designed to create a durable, waterproof seal that will prevent further leaks and damage. Carefully measure the size of the holes or cracks, and cut the tape to fit the area, ensuring a tight, secure seal.

Apply Rubberized Coating

To create a long-lasting, waterproof barrier, apply a flexible sealant like Flex Seal Liquid Rubber Sealant Coating to the entire interior of the pan, including the bottom and up the sides. This rubberized coating will help prevent future rust and leaks, ensuring your swamp cooler operates at its best for years to come. Apply the coating in thin, even layers, allowing each layer to dry completely before adding the next.

Optional Tune-Ups

While repairing the rusted pan is the primary focus, it’s also a good idea to consider replacing the motor/fan V-belt and the Aspen Cooler Pads as part of your maintenance routine. These components can wear out over time, reducing the efficiency and performance of your swamp cooler.

To replace the motor/fan V-belt, measure the existing belt and purchase a replacement that matches the size and specifications. Carefully remove the old belt and install the new one, ensuring it is properly aligned and tensioned.

For the Aspen Cooler Pads, measure the dimensions of the existing pads and purchase replacements that fit your cooler model. Follow the manufacturer’s instructions for properly installing the new pads, ensuring a snug, secure fit.

Advanced Hands-On Details

Safety First: Always wear appropriate personal protective equipment (PPE), such as safety glasses, gloves, and a mask, when working with tools and chemicals.

Preparation: Ensure the pan is completely clean and dry before applying paint, patch & seal tape, and rubberized coating. This will help ensure a strong, long-lasting bond.

Patience: Allow sufficient drying time between each step, especially when applying paint and rubberized coating. Rushing the process can lead to poor results.

Measurements: Carefully measure the motor/fan V-belt and Aspen Cooler Pads to ensure a proper fit. Incorrect measurements can lead to improper installation and reduced performance.

By following these detailed steps and using the recommended materials and tools, you can effectively fix a rusted swamp cooler and restore it to its optimal performance. Remember to always prioritize safety and take your time to ensure a successful repair.
