Coolant leak front of engine (not water pump)

[ZukesMcGee]

I need help figuring out a coolant leak. It's a 3.4 jdm engine I swapped a few months ago. I changed the water pump and timing belt in the process, the old water pump looked good and dry but I put a new on in anyways. The leak is Above the water pump and wraps around the side of the engine, to above the oil filter. Sometimes it leaks pretty bad and sometimes it doesn't leak at all. Coolant drips down onto the front crossmember and then onto the ground, usually when parked downhill. Thanks for any help!

It is also not coming from the upper coolant hose as far as I can tell.

I strongly suggest you invest in a pressure tester rather than solicit guesses on the internet.

Water inlet on intake...manifold gasket..head gasket..

It ended up being the coolant line that hooks to the throttle body. It would leak onto the intake manifold. Park facing slightly downhill and it drips off the front of the engine. Park facing uphill and it drips down the back. Very deceiving leak but found it pretty quick once I started really looking.

Thanks for posting the cause of your leak.
