Okay, so Im driving and i see smoke coming out the hood. i parked to check wat was it and it was the fat hose connected to the radiator came off. antifreez everywhere. so i put the back on. idk why the enginge overheated since the fan is working well. then at nite the same thing happend but worse, the fat hose blew off again this time spilled alllll anitfreez. my engine is overhearting but idk why. the fan is working good. there was coolant in here. and get this, the little meter that tells you the temp of the cengine stoped working... any suggestions??? pllzz help

replace the hose, and the clamps. fill it with more antifreeze/water, get the air out of the system. Your gauge is doing what its supposed to, so is the fan.

How do i take the air out?
and the needdle to tell me if its cool or not does not work at all
so idk if the engine is heating or not...
i put water in the radiator and today it didnt heat up ..but still that needle .

I made the mistake when I replaced the radiator hoses to only use a screwdriver to tighten the clamps. One of the hoses came off the next day. You need to get a socket on there and tighten it. It's surprising how much more tight it will go with the socket compared to a screwdriver.

Coolant gauge not working? Hmmm Maybe the coolant temp sensor in the front of the block got splashed with boiling coolant? Don't know how to solve that one.

Any car will overheat with a hose off. Doesn't matter how good the cooling system is.

To get the bubbles out. Start the car cold and leave the radiator cap off. Let it warm up to around 100°F (2 minutes or so?) As the fluid in the radiator drops, add more coolant. May help to have somebody gently raise the throttle a bit while you're pouring into the radiator. After that it will be very full. Bubbles should be a thing of the past.

replace ur coolant temp sensor as well
