Help diagnose coolant leak
My 2010 MCS with 65k miles is losing coolant very slowly. There are no drips on the garage floor and the cooling system easily passes a pressure test. A quick review of this forum suggests the usual suspects are water pump and thermostat housing. Can anyone offer tips on telling where the fluid is going?

+1 Its all here. Been there and done all of this myself. We were the first to mention the pooling effect.

At first you can get a small hairline crack at the bottom of the thermostat that leak a couple drips on to the transmission, ( why u cant find it ) , then after a while it pools and then drips down the back.
