A faulty cooling fan can put many parts at risk under your hood. If your electric fan isn't blowing cool air onto the engine like it should, the problem could involve the pigtail connectors. These inexpensive replacements are made for use with all Maradyne fans. The connectors have a socket to accept the fan wiring, while the other end is a pigtail—to attach to the on-car wiring. When it's time to update your worn-out wiring, choose genuine Maradyne parts!
