Ok so heres the deal, i recently replaced my temp sensor which was recommended by the techs at this site which fixed the previous problem. now ever since i had that replaced i am frequently going low on coolant. im not sure if there is air in the system or whats going on but it started as to having to fill it every 2 weeks, then once every week now every few days. there are no signs of leaking under the car and no white fumes from the engine
