2019 Tacoma TRD Sport 3.5 L 89,000 miles. Saw a small puddle under the DS front other day and then while driving started to hear a rattle that kept getting louder. Parked the truck, coolant was low, dripping steady on DS front. looked over hoses etc all appear good. Can I assume that the the "weep" hole leak I have seen mentioned? Any good step by step water pump replacement or videos out there? Thanks
