When to check your coolant or antifreeze level?

Always check your coolant level when the car is cold. If you happen to have an older vehicle without a visible overflow and fill tank, you’ll have to check the antifreeze/coolant level by looking into the radiator. There is no dipstick or another meter to tell you whether you have enough coolant in the radiator on these older vehicles.

What do you need to know about antifreeze poisoning?

Antifreeze Poisoning. Overview. Antifreeze is a liquid that prevents the radiator in cars from freezing or overheating. It’s also known as engine coolant. Although water-based, antifreeze also contains liquid alcohols like ethylene glycol, propylene glycol, and methanol. Propylene glycol is also an ingredient in some foods and cosmetics.

What’s the difference between antifreeze and coolant in a car?

Antifreeze is a concentrated additive which, when mixed with coolant, helps protect your car’s radiator from freezing during the winter. It’s usually orange or green in colour. Orange antifreeze has an extended lifespan thanks to a different corrosion inhibitor used.

What should you do if your car has antifreeze in it?

Yep, do nothing. Well, do nothing for about an hour or so. This is because, as we said above, antifreeze and engine oil do not mix well! So if you leave the car alone for just an hour or so, the antifreeze will sink to the bottom of the oil sump.

What is the correct way to check antifreeze?

How to Check a Vehicle’s Coolant/Antifreeze Rather than open the cap on the radiator, just check to see whether the liquid reaches the “Full” line on the side of the coolant reservoir shown here. Coolant is usually red, green, blue, or yellow. If the coolant has a sludgy, oily surface, immediately take the vehicle to your mechanic to check for internal head gasket leakage.

How do you know when you need antifreeze?

The temperature gauge reads hotter than normal when the engine is running Antifreeze leaks and puddles beneath your vehicle (orange or green fluid) A grinding noise is coming from under the hood of your car Flecks or bits of rust start to show up in the antifreeze/coolant liquid Steam or an odor similar to boiling maple syrup is coming from the engine

How often should you have to put in antifreeze?

For “ordinary” antifreeze, the vehicle manufacturers generally recommend coolant changes every two to three years or 30,000 miles. Others say it’s not a bad idea to change the coolant every year for maximum corrosion protection — especially in vehicles that have aluminum heads, blocks or radiators.

How to tell if your vehicle has an antifreeze leak?

Clues You Have an Antifreeze Leak A sweet aroma that you notice from outside the vehicle, coming from the vehicle after you’ve driven it. Puddles under the car of lime-green, orange, pink, or blue-green after you’ve parked. Antifreeze makers use those dye colors to differentiate coolant from other fluids used in cars. The car starts running hot or overheating.
