hello, my 4ag 1.6 FWD normal driving and the temp meter up to halfway and stay no change. I try take out the thermostat and let the fan running at the time but the needle also going to halfway. I thinks it will too hot for my car cause very hot weather here. Is there any way to do to make it down?? And also the water outlet blocked and have 2 wire plug there. Does it block the water out cause these?
