Improving Your Car

If your convertible's engine fan stops moving at random intervals, due to rusted blades and debris caked on portions of each one, remove damage and residue by completing the steps below. Once you have finished, the fan will circulate air over the radiator in an even manner, preventing your vehicle's engine from overheating.

Materials

• rust-dissolving spray
• naval jelly
• foam brush
• scouring pad
• water hose
• industrial-strength detergent
• bucket of warm water
• plastic scraper
• lint-free cloth
• shop vacuum cleaner (with hose attachment)
• rust-inhibiting spray

Apply A Rust Dissolving Product And Wipe Surfaces With A Scouring Pad

Apply an even amount of a rust dissolving spray on each portion of the fan that is corroded. If the rust is thick in some sections, coat them with naval jelly. Each product will begin to dissolve rust after several minutes have passed. When this occurs, move a scouring pad back and forth over each corroded area to assist with removing them completely. After all of the rust has been eliminated, use a water hose to rinse the fan and blades off.

Clean The Fan And Vacuum Up Tiny Particles

Apply a small amount of industrial-strength detergent to a damp sponge and wipe it over encrusted dirt. Rinse the sponge with warm water as it becomes covered with dirt. Use the tip of a putty knife to loosen hardened residue. Wipe off each part of the fan with plain water once all of the dirt has been eliminated. Dry each part of the fan with a lint-free cloth. Use a shop vacuum cleaner's hose to suck up tiny particles of dirt that were not removed with the previous cleaning steps.

Protect The Blades From Corrosion With An Inhibitor

In order to protect the fan's blades from becoming rusted again, apply a rust-inhibiting spray to them. When applying the spray, hold the container several inches from each part of the fan so that the product doesn't drip while it is being administered. Leave your convertible's hood open while you wait for the inhibitor to dry.

After the fan's blades have a dry surface, start your vehicle and visually inspect the fan. If the blades are moving in a smooth manner, the rust removal and cleaning steps were performed correctly. The inhibitor will continue to protect the blades from corrosion, and a new application of the product can be applied when it is needed in order to provide continuous protection.
