2004 2.5L - Coolant leak

Have a slow coolant leak toward the front of the vehicle

Seems to be draining down on either side of the radiator

Cant seem to locate the leak

Anyone had this issue?

Probably expansion tank. I couldn’t get mine to open until I applied 18 psi of pressure.

If BOTH sides of radiator, it would be the end tanks of the rad, but with the same pressure game as above.

Likely way-past time to have all the hoses replaced, as well as the expansion tank. And probably the water pump too.

Agreed those parts are past their prime.

I pumped my system up with a pressure tester until the crack opened up, which wasn’t visible otherwise. Even with the expansion tank out of the car, it was barely visible even knowing exactly where it was.
