Unable to locate coolant leak coming from under air chamber housing right close to bypass hose in the front, any help out there? And what is the best coolant to use

Maybe a pic of the area in question will help us help you.

I had a small dribble leak just under the thermostat inlet. I replaced the hose and both spring clamps. No more leak. The hose was original and looked fine so my guess was the clamp was getting loose. But either way the leak stopped.

From the plastic water outlet that covers the thermostat is one possibility. It may need a new gasket.

You can get Toyota red coolant at a Toyota dealer. I bought 100% coolant there and mixed with water to get it 50/50.
