Can you mix coolant?

The short answer is that you can mix different coolant brands and mixtures as long as they are the same type of coolant. The color doesn't matter as much since it's just a dye. via

How long until I can open radiator cap?

Typically though it should be left to cool for 1-2 hours before it's cooled sufficiently to open the rad cap safely. If you're actually trying to check the coolant level then you probably need to wait more like 3-5 hours (as if the coolant is still warm it will show a falsely high reading due to expansion). via

What happens if my radiator cap is broken?

When your radiator cap does not seal properly, air could make its way inside of the cooling system. This will cause air pockets to get inside of the heater core, thermostat, and radiator hoses. As a result, the engine will start to overheat because it cannot sustain a temperature that is consistent. via

Will a bad radiator cap cause a car to overheat?

The radiator cap is often overlooked as being a cause of engine overheating. A radiator cap looks simple but, is critical for a properly operating cooling system. A faulty radiator cap can result in engine overheating, loss of coolant or major engine damage. via

What happens if your coolant reservoir is too full?

When you overfill the coolant reservoir, there won't be much space left for the heated coolant to expand. As a result of which, the pressure inside the reservoir would increase gradually. When this happens, the cap of the tank will open, and the hot coolant would pop out like a puddle of lava. via

How do I know what size radiator cap I need?

Know the Pressure Rating

Each cap is different depending on the model of your car. The owner's manual often has the correct pressure rating listed that is necessary for your car. If the pressure rating is not listed in the owner's manual, it will be under the hood on top of your old radiator cap. via

What kind of radiator cap do I need?

Cars with air conditioning and/or heavy-duty cooling got a 16-pound cap. If you are using a water-based coolant, then you should stick to these ratings. You can use a 16-pound cap on a standard-duty cooling system if you want, and caps are available with pressure ratings of 17, 18, and even 20 pounds. via
