if there is coolant already in the lines, block and radiator then you can safely top-up, but if you are replacing fluid, say after a leak then you should mix it 50/50 with water. Good luck Badgirl.
Antifreeze should be a 50/50 mix with water. If you bought pure coolant, mix with water. If you bought premix (already 50/50) pour in straight.
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.
Drain and flush the system. Pour in one gallon of pure antifreeze, and then top it off with distilled water. This will provide protection to around -25 Degrees F. If adding fluid to an engine with low coolant, look for the stem sticking up in the inside of the coolant overflow reservoir and add enough 50/50 mix to reach the top of the stem.
No , it's best to add coolant when the engine is cold
My engine coolant is a 50 / 50 mix of antifreeze and distilled water so adding water will just dilute the mixture more and weaken the antifreeze so the coolant mixture will freeze at a warmer temperature and it will reduce the corrosion protection if there is not at least 40 % antifreeze
Yes. Never add pure antifreeze. Pure antifreeze will actually freeze before a 50/50 mix. Add coolant that is a 50/50 mix of antifreeze and distilled water. You can buy it already pre-mixed.
You dilute your antifreeze. If you buy prediluted 50/50 antifreeze, then you'll dilute it more than you're supposed to. If you buy straight 100% antifreeze, you're actually supposed to dilute it yourself by adding an equal amount of water to the antifreeze you put it. Your vehicle will be fine. Stop freaking out. Get a coolant flush.
Don't mix Dex-Cool with other types of coolant. You will be asking for trouble and paying a premium to get it. See link.
When you add engine coolant to a 2003 Jeep Grand Cherokee because the low coolant indicator has come on, you should add to the reserve tank and the radiator if they are low. Sometimes, just the reserve tank needs filled.
If you're adding coolant to the reservoir often, you have a leak somewhere. Have the cooling system pressure tested. That may force the leak to show up.
sorry, im blondeWell, I'm NOT a blonde.With the engine running, open the hood and you should see an opaque white overflow tank with green (hopefully) antifreeze in it. On the side of the tank are level marks - one for an engine COLD level and the other for the engine WARM or HOT level. Since the engine will be WARM / HOT while you are adding the antifreeze you'll be using this mark as your reference. Open the plastic flap on the top of the overflow tank and slowly add antifreeze until it reaches the lower edge of the WARM/HOT mark on the tank. Close the flap on the tank to preserve system pressure and prevent antifreeze from spraying all over the engine compartment.*** Under no circumstances are you to add coolant directly through the radiator. The system is under pressure and must remain closed. The overflow tank is the only way to safely add antifreeze/coolant to the system.
It lowers the freezing point.
