The car overheated,though I didn't allow it to because I monitor the temperature gauge once it was over the half way mark,I switched off the Ac and parked. The reservoir is drained, I am waiting for the engine to cool of better I add water to get me home.Note I top up it up a bit this morning again.I ve had the thermostat removed if that affects in any way.I don't know at this point maybe I need to use a gasket sealant to remove doubts because I ve already changed water pump and even bought a new bigger radiator and am still dealing with this and also it mostly tends to overheat when it rains
