I often tip about HF's kit for pressurizing the coolant system. It makes life so much easier in the case of sneaky coolant leaks.

Quick update, the slow coolant leak under the reservoir was fixed after replacing the reservoir. I reused the old clamp. I did notice that there were many "hair lines" under the coolant reservoir nearby the bottom hose area. Bottom of the reservoir was very dark in color.

With the old coolant reservoir out, I also replaced the cracked timing belt top back cover - the one next to the spark plug cover.
