I have a 2006 lbz now has 422,000 miles but have a coolant leak in that same area 🤔. I will check it out.

Good job. How many miles are on your dad’s truck.

Just under 300k at this point he’s the one owner since factory had the truck since 07 drives it every day

So you got all them gaskets and o rings, loosened up the bolts that hold it to the block then half assed and just replaced 2 of the gaskets 😂.
