    Hey everyone as per the title I have a coolant leak on my 2006 4.7 V8 Tundra and I did a pressure test and believe that this where it leads to, I'm not certain but my guess is that this is the water pump if im not wrong which I had replaced 2 years ago along with a timing belt, could it just be a seal I'm not sure where the wrap hole is on here. All help/advice is appreciated.
    P.s. as you can guess I'm not super experienced with this stuff 20211206_122618~2.jpg 20211206_122815.jpg 20211206_122635_HDR~2.jpg

    thats the crank wheel that your red arrowing is pointing and behind that is a cover that covers the crank seal/oil pump. you could have a combo leak of oil from that bad seal plus coolant mixed coming from higher. your water pump is higher up above the oil pump cover and typically can see that type leak above the crankwheel. sometime the waterpump leaks and trickles over yonder to and around the oil filter region. could be bad hose or o-rings going into throotle body. lots of action there.

    might be timing belt change time where everything can be addressed simultaneously. 2-3 day diy not for weak hearted. 2 day job at mechanics and $..

    I'm at 203000 miles and I had timing belt and water pump replaced around 180000 I'll have a better look at it in the morning

    water pump, or possibly the coolant crossover between the two heads is leaking and running down the block to where you see it
