ok, she's been randomly leaking for a few days. mostly i see coolant on the ground in the morning. so i got it pressure tested and they said its got no pressure in the system. it was cold when they did the test. i orginally thought i overfilled the coolant, its been dripping off and on for 2 or more years, i saw a leak by the coolant bypass hose, but that was awhile back. the radiator is 2 years old at best and looks good. no coolant could be found while it was on the lift, im leaning towards the pump, but she's not overheating, heats works fine, but i can smell coolant when i turn on the heat sometimes. rarely. wtf???? ideas???

 

put some dye in the system and pressurize it, then search for the dye.
