    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 one 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

    I actually found it today. It was the coolant line that connects to the throttle body. It would leak onto the intake manifold and down the front of the engine, making it difficult to find.
