On top of that, when coolant makes contact with the extremely hot metal components under the hood, you will notice a strong burning coolant smell inside and outside the vehicle. The underhood area is filled with electronic components. Antifreeze blowing around inside the engine compartment could easily damage such electronics. Devices like the alternator, engine sensors and controllers, ignition coils and spark plugs, etc. Correcting the moisture damage to electronic components could be costly as well.
There are many types of coolant. The majority of them are toxic. Consuming this antifreeze off the driveway could result in the death of domestic animals and wild animals as well. Be kind to animals… never overfill your cooling system. Check your auto parts store or hardware store take a different car.
Such stores generally sell small hand-powered suction pumps with lengths of plastic tubing that will work well for sucking extra fluid from the coolant tank. Mityvac is a popular product but the Pennzoil Multi-Use Pump is a good, cheap option as well. A plastic turkey baster available at most grocery or large discount stores can be used as well.
Save the coolant in a sturdy plastic container with a snug lid. Store it well out of the reach of children. Comply with local environmental laws should you decide to discard it. Doing so poses a risk of causing the coolant overflow problems discussed above. While this is not by itself a safety risk, the three problems discussed above could happen.
For these reasons, unless you have an emergency situation, avoid operation of your vehicle until the coolant level has been corrected.
Table of Contents. The same logic applies. You'll want to make sure that the coolant is as the "Low" or "Min" level when the engine is cool. The minimum mark is the lowest amount of coolant your engine will need and going below this may cause overheating problems. If this is the case, any excess will need to be removed from the system and this can happen via an overflow hose, or a hose may become damaged and burst. This is where the real dangers of overfilling your coolant lie. Hot coolant leaking throughout your engine bay can cause serious damage to wiring and electrical components.
If you do end up with a burst hose, your engine could be starved of coolant and cause some pretty big problems. A less serious side effect is the puddle of coloured liquid that will be pooling beneath your car, which in most cases is just an inconvenience. The coolant tank, also known as an anti-freeze tank, is a reservoir designed to accommodate the natural expansion and contraction of coolant.
Coolant expands as it heats and contracts when it cools. The extra space prevents damage to your engine and hoses. The marks are used to gauge the level of coolant in the vehicle when the engine is at different temperatures.
The lower of the two marks used when the engine is cold, while the other mark is used when the engine is hot. Most of the time, excess coolant is expelled from an overflow hose. In worst case scenarios, overfilling your antifreeze tank can lead to electrical damage if overflow comes into contact with engine wiring. Modern cars are equipped with a sensor inside the coolant reservoir. This floating sensor will trigger a warning light on your dashboard if the level of coolant becomes too low.
If your coolant is low, add some more coolant. If your coolant levels appear fine, it may be time to take your car to a mechanic. That way, you can rule out a faulty sensor.
