when driving on the highway, i hear this noise like lake a muffler going bad, but there is no hole in my muffler. I tried tightening the valv on the hose but it continues to leak if the car idle for atleast 2 minutes
my car leaks all the coolant, I have to replace coolant almost every day. on 2002 Toyota RAV4
DO NOT DRIVE THIS VEHICLE ANYMORE! Or you will be replacing the engine soon. You need to take it to person/shop that can pressurize the cooling system to find the leak. It may be already to be late.
