I count 1 coolant drip off the oil pan every 18-22 seconds. If I let the level run down so the light comes on, it doesnt leak until I fill the reservoir up again, and then it drips. It drips running or not. The highest place I can see green coolant is at the rearmost lower bolt that secures the A/C Compressor mounting bracket to the engine. Not sure if there is a water jacket behind the bolt, I removed both rearmost bolts that hold that aluminum bracket to the block and sealed with RTV, the leak did not change frequency. I notice that the water pump is right above the A/C Comp. But to the best of my ability I cannot see any leak directly from the water pump.

Thanks in advance.
