It will overheat, unless you can successfully air cool it.
( NO ) with the engine cool
antifreeze keeps your car from overheating, it flows thru your radiator hose, without it your motor would blow
No , it's best to add coolant when the engine is cold
i believe your heater core has died
Your engine should be cold ( to be on the safe side) when adding antifreeze/coolant. i let the car sit overnight and then add it.
Antifreeze/Coolant is a fluid that prevents the car from overheating or becoming so cold that it won't start. Without it, in the summer, your car would run too hot, and in the winter, your car wouldn't run at all.
No Hydrogen is a very flammable gas, there for it would react.
You can run up to 75 percent antifreeze without any trouble. -------------------------------------------------------------------------------------------------- Actually , Ford states not to exceed ( 60 % antifreeze )
=To properly flush the antifreeze on a 2002 Yukon you will need a antifreeze vacume system you will need to start the car and have it running turn on all the heating modules to high and have the car reved at about 1.5 r.p.m, or a little higher to activate the vaccume this will start sucking the old antifreeze out. When the radiator is empty{you will know when it is empty because there will be no more antifreeze coming out}you can then fill it up with half and half antifreeze[half water half antifreeze].=
So that the water used as coolant in most car radiators does not freeze overnight. If it does then, because ice expands as it freezes and melts, it can crack the engine block. The antifreeze lowers the freezing point of the coolant and reduces the risk. The more antifreeze, the less risk of freezing. But too much and it will boil when the car is running. Additives in antifreeze also reduces corrosion and raises the boiling point.
You normally smell the antifreeze so open the hood and look for a leak before you see it big time running out from under your car.
if you run your engine without antifreeze your car will overheat and ruin the engine.
