I have Suzuki Mehran 2011, few months ago i was travelling from Lahore to Sahiwal and due to radiator leakage problem engine turned off, i called my mechanic and he suggested to remove radiator lid and try to turn on and it worked i managed to go my home town since then i have water reduction problem and mechanic is saying it will be resolved by engine overhauling. Car milage is around 80k and i have to fill water after every 3-4 days. Please suggest can it be resolved without engine overhauling or i continue by filling water and drive.
