Bruce,
I had a slow leak which I could by looking at coolant stains on the absorbent pad kept under the engine. It is possible that your leak is slow enough that the coolant evaporates before getting to the bilge. To find mine, I used an ultraviolet flashlight https://smile.amazon.com/gp/product/B00RV8PREI/ref=oh_aui_detailpage_o01_s00?ie=UTF8 <https://smile.amazon.com/gp/product/B00RV8PREI/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1> &psc=1 and Dex-Cool leak detector tracer https://smile.amazon.com/gp/product/B008I2VKNI/ref=oh_aui_detailpage_o02_s00?ie=UTF8 <https://smile.amazon.com/gp/product/B008I2VKNI/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1> &psc=1 This worked well as it was next to impossible to see the coolant leak which in my case came from the coolant pump.
