Q: Clicking noise

asked by on

When my truck starts, I hear a clicking noise. I tried to put fluids in it, and green liquid started coming out of the bottom.

Depending on how the click noise sounds, it may be a normal engine noise, or it could signify a problem. The green fluid you are seeing is most likely coolant. The leak will need to be found and repaired. I would ask for assistance from one of the mechanics at YourMechanic so they can come to your location, and diagnose your leak and clicking noise.
