If you can't get up the hill without loading the engine to the point it overheats, there isn't much you can do about that. The engine becomes extremely hot and heat is transferred from the engine to the coolant and finally to the radiator. My car exhibited no signs of leaking and based off of that I drove it. Use stop leak if the leak is not too great. It also helps the coolant boil at a higher temp. If you do this and the temperature stays within normal range (which is often the case) pull over when you can and check the coolant level. The radiator generates high pressure and the released steam can cause severe burns. The turbulator helps to regulate the amount of coolant flowing through the radiator tubes. Why Coolant is Better for Car Instead of Mineral Water January 30, 2017 December 19, 2018 Rahadian Abdhi 1 Comment Caruser.net â Radiator is an automobile engine cooling device. First thing I'd try to figure out is how quickly it leaks - run it, stick your head underneath it as check if there is any visible leaking. Ethylene glycol is extremely poisonous. Lower loads on the engine means less cooling is required, drive slowly. Obviously, you carry extra water/coolant with you when you go down this path. To make a painfully long story short, I had a lot of car issues the past few days and my car was leaking coolant. Using these techniques you might be able to get a car where you need it to be with a compromised cooling system. If your car is leaking coolant get it fixed and put in the recomended coolant for your car. For it to achieve its necessary thermal range, coolant must be mixed 50/50 with water. Water is often mixed with the coolant in a 50:50 ratio; you can also add antifreeze if you live in areas with extremely cold temperatures. An understanding of how the radiator works is crucial when dealing with water in the radiator. A faulty radiator cap will cause the coolant to flow into the reservoir. When coolant and antifreeze is mixed with the water it changes the temperature at which the water will freeze or boil. Please read this question on driving without coolant! After this I drove the car trying to maintain under 3000 rpm and made it to the mechanic's shop like that. Faulty radiator caps cause unwanted air to flow into the thermostat, radiator core and radiator hoses. In general, water on its own tends to cool better than water + antifreeze, so you're not risking any damage from running water in the engine provided the outside temperature doesn't drop below freezing. @JuannStrauss - It is interesting that you mention that. If there is, don't drive it. It is worthwhile to also check the auto transmission fluid, because if that is low the tranny is running hotter than normal and most radiators have a section that is your transmission fluid cooler which is mounted to the radiator putting additional heat on the cooling system. According to me, cold water won't make a difference, since it will be heated to 160+ in under a few minutes. Coolant has a higher boiling temperature than water, so it stays 'cooler' better than just water alone. but its far better than running empty coolant. If it is out of hand then AAA will pick up the slack. If it's not leaking that badly I'd be tempted to top it up with plain water just to check if that reduces the temperature to something more normal. If you think there is a leak and have 30 miles drive, then you can reserve some pure water with ride and use it. Great answers here, I just wanted to post what I actually ended up doing in the hopes of it helping someone at some point, or maybe to satisfy curiosity. You can also provide a link from the web.

Recently, I was informed that a car I share ('02 Nissan Sentra) was close to overheating. Never had much luck with this, or any other "seal" voodoo. This will increase the cooling system capacity by allowing the heater core to dissipate engine heat -- obviously at the expense of cabin comfort. Mostly I was concerned with whether or not to just use water in the system while testing to see how bad the leak/situation was.
