Coolant leak I have no idea where it's coming from

[jaysan]

I have a puddle in my 2002 gmc safari with 160879 miles . It's leaking from the transmission and engine like where it mates up ANY help is appreciated

Is this inside the cabin or or under the van?

Under the car . I checked the passenger side carpet and it's dry so I don't think it's the heater core . I have replaced the radiator , thermo stat , water pump , and a hose within the last year .

You may see it from the front but certainly from inside, open the doghouse and look on top of the block.
Intake manifold.

Sounds like woodbutcher hit the nail on the head, intake gasket leak

For jays sake I hope not as they are such a PITA. Considering the alternatives, caught and fixed early, not leaking internally, it ain't terminal so that's a good thing.

Got my fingers crossed for ya!

Yeah my oil is not milky colored so I hope I'm ok lol

When my intake gasket went at first it was a small leak I couldn't locate. I stopped at the plumbing supply to get parts so I could do a pressure test on the system. It was on a busy road so I jumped the gas to get into traffic and that is when the leak turned geyser. I pulled into the other end of the parking lot of the supply house, returned the parts and called AAA.
