Hi everyone, I started hearing a ticking noise coming from my 2016 SLT GMC Sierra, and I wanted to reach out for advice. I’ve attached a video I recorded of the sound to help identify it. Upon inspecting it, I found the Radiator fluid was extremely low and fluid was leaking from one of side hoses! Could it be a Lifter failure? Water pump failure? Exhaust leak? I’d appreciate any guidance on what this sound might be. No CHECK ENGINE light yet! Note: The third clip when I am accelerating, I could hear two forms of ticks, the usual lifters sound, and this new one! finalVideo 4.mov
