Where's the water going no visible leaks thermostat removed

Hello, if the problem is occurring mostly during stop and go driving, it's likely that not enough air flow is crossing the radiator to cool the coolant. This could be due to cooling fans that may not be working as designed. I would check for possible cooling fan concerns before anything else. I would also highly suggest restoring the thermostat to the proper position in the engine, as you are not helping anything by removing it -- in fact, you are causing more problems in other areas.
