DEX COOL COOLANT TASTE MANUAL
MaintenanceĬheck your owner’s manual to find out how often you should get your engine coolant flushed and replaced. If you check your coolant reservoir while the engine is hot, it could explode.
On that note, never put plain water in your coolant reservoir unless it’s an emergency. Many coolant solutions are ready to use, but check the bottle in case it’s a concentrated formula that must be mixed with distilled water first. Carefully open the reservoir cap and add the coolant until it reaches the fill line. Coolant systems are pressurized, which means the reservoir is very dangerous to open while it’s hot. Don’t attempt to handle this right after the vehicle has been driven. Refilling the fluid antifreeze or coolant is something you should only do when the engine is cool. It’s even worse than that time a waiter came and topped off your Coca Cola with iced tea on accident. Mixing different types can damage your engine, so be careful. It’s important to check which kind is currently in your vehicle so that you can refill it with the same formula.

If your engine is starved of coolant it will overheat in a matter of minutes, which usually causes irreversible and expensive damage. If the level is below the minimum line, you will need to add coolant to keep your car and radiator happy. It should be a transparent little tank with minimum and maximum lines shown on the side. Locate the coolant reservoir under the hood of your vehicle. Check out the following tips for checking and refilling your car’s coolant. Just like you need to check and refill your motor oil to prevent corrosion, you'll want to make sure your coolant level is always good to go too. Vehicle coolant is also known as antifreeze because it keeps the liquid in the radiator from freezing once the temperature gets down to a freezing point.
It’s the radiator’s job to regulate the engine’s temperature and act as a cooling system to keep it from overheating, but it can’t do its job without engine coolant.
