Key Takeaway Th ere is no overstating how much vehicles can be adversely aff ected by exposure to fl oodwater. Maintenance personnel should be aware of how damage to a vehicle’s interior, engine and other components could negatively impact a vehicle’s safety, its future reliability and its trade-in or resale value. While putting in both time and eff ort to inspect, assess and salvage a fl ooded vehicle is a recommended task, the bottom line is that a vehicle that has sustained extensive damage, the vast majority of the time, ends up being deemed a total loss.

Any that are damaged need to be replaced immediately. Th en, maintenance personnel must ensure all water is removed from the air fi lter and compressor air inlet. If water is present in the compressor, then its oil needs to be drained from the crankcase. In addition, Meritor recommends replacing the air compressor in cases where a fl ood-damaged vehicle’s engine is also being replaced. When it comes to inspecting a vehicle’s air dryer components for flood damage, Meritor officials recommend checking air lines and connections for both water and contaminant damage, as well as the presence of rust and corrosion. Damaged components must be replaced immediately, but, in many cases, replacing the entire air dryer is a more cost-eff ective option. Also, if excessive moisture is found, the air dryer cartridge needs to be replaced as well. Offi cials at Meritor also stress the importance of inspecting all air brake control valves for water and contaminant damage when dealing with a fl ood-damaged vehicle. As with the aforementioned vehicle components, anything damaged must be replaced. In addition, company offi - cials recommend cleaning and lubricating foot valve and quick release valve pins and plates as well. When addressing both pneumatic and hydraulic anti-lock brake system (ABS) wheel end sensing systems that have been exposed to fl oodwater, Meritor suggests inspecting sensors, sensor spring clips and tooth wheels for water and contaminant damage that includes, but is not limited to, rust and corrosion. Also, the company recommends inspecting and cleaning all spring clip mounting blocks, lubricating sensors and spring clips, as well as replacing all damaged components. Electrical connections must be inspected, cleaned and dried. Dielectric grease should be applied to terminals as well. In addition, the installation of the brake system needs to be checked with a diagnostic tool, and any improperly functioning components must be replaced. ©2017 Federal-Mogul Motorparts Corporation.
