Fresh antifreeze is a clear brightly coloured liquid, usually blue, red, green, violet, yellow or orange but this will vary depending on the manufacturer’s formulation. Over time, your coolant will become dirty losing its colour and becoming darker, often an oxidized shade of brown.Jun 7, 2016
The truth is, color is not a reliable predictor for what type of coolant you have. For example, OAT coolants are usually orange, yellow, red or purple. … Then the older IAT coolant is green. Coolants that manufacturers sell can confuse matters even more, like Honda’s blue coolant.
Black coolant can be caused by deterating radiator hoses, crud in the cooling system, and oil getting into the coolant. Not only engine oil from a blown head gasket, or an intake manifold leak, but transmission fluid from a leak in the cooler in the radiator.
It’s perfectly backwards compatible if you want to do that. But you really don’t want to mix them, it’s not that good of an idea to mix them. If you want to have the correct coolant added for you, consider YourMechanic. They will be able to come to your home or office to perform this service.

There is green antifreeze and orange antifreeze. … These days you can actually get yellow antifreeze, blue antifreeze, pink antifreeze and more. The fact is, mixing these liquids is not safe.
While the manufacturers of these coolants recommend only using them in an aluminum radiator, as opposed to the copper/brass radiators, we still don’t recommend them in our all-aluminum radiators. … We recommend the traditional yellow/green coolant because it has always worked for us.
Don’t open the caps on either of these systems when the engine is hot; if you do, hot coolant may be ejected. Coolant is usually red, green, blue, or yellow. If it looks colorless, looks rusty, or has things floating around in it, flush your cooling system and add new coolant.
Vehicle Overheating and High Temperature Gauge
The primary role that coolant plays in your vehicle’s functioning is keeping your engine temperatures low. If you find that your temperature gauge is always high and your engine is frequently overheating, chances are that you need a coolant flush.
Watch for signs of oil or rust.
The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.
A strange dark or gray, milky color in your coolant, or white antifreeze, is caused by a significant problem with your head gasket. … When you notice milky oil in the car, it’s because the coolant has leaked into the combustion chambers and mixed with the motor oil, so the color is from the diluted oil.
Other potential leak culprits include a bad radiator cap, blocked radiator or damaged sensor. Discolored coolant: Coolant color should never change, but it can when coolant gets contaminated with debris or it’s been in your car so long that the additives in it deplete.
Yes, it’s possible. Also, the bit you lost that you think may be a leaking pipe is actually being turned to steam and blown out your exhaust. The car runs fine until the engine gets hot enough for the thermostat to open up, at which point exhaust gases are let into the radiator.
You may have a blown head gasket but not realize it as there is no coolant mixing with oil or leaking oil. … When you have a blown head gasket, you may have no heat, no white smoke, no start, no check engine light, or even no overheating in some cases.
There are standard anti-freezes that are red and cars that have Dexcool® will be labeled as such. Another myth is that Dexcool® is not glycol based. … Both ethylene glycol (EG) and propylene glycol (PG) are used as the antifreeze base. From here the additional additives and inhibitors are added.
As a quick guide, if your topping up the coolant levels, use the same color as is in the vehicle already. However just because it’s the same color doesn’t necessarily mean it’s the same type. … For example, Toyota has green and red, but it depends on the year and model of the vehicle as to which kind is needed.
The key difference between red and green antifreeze is that red antifreeze lasts longer than green antifreeze. An antifreeze contains ethylene glycol and propylene glycol as the bases. So it’s a better antifreeze to use. …
You may have a coolant leak, a power steering leak or a transmission fluid leak. If the liquid is a water like substance and consistency with a pink color, this suggests you may have a coolant leak. There is a hose that goes from your car’s engine to the radiator that can sometimes leak.
The pink coolant is an OAT (organic acid technology) that typically has a longer service life. The red coolant on the other hand is an IAT (inorganic acid technology) that is considered to be more “conventional” but still longer lasting than some other coolants on the market.
And if you mix the two types of coolant, nothing terrible is going to happen — nothing is going to blow up or melt — but a mixture of the two types of coolants won’t have as much rust protection as either one individually.
And you do need at least a 70/30 antifreeze/water mix for the best results. Typically, Valvoline says, coolant comes in green. … These different types of antifreeze all do broadly the same things. They prevent water from freezing and boiling off and inhibit corrosion and mineral deposits in the radiator.
There are two fluids used by your vehicle that are red. These are the automatic transmission fluid and the power steering. Both of these are hydraulic fluids. You’ll want to check your owner’s manual to see if your vehicle, like some others, actually uses automatic transmission fluid in the power steering system.
While green coolant is often thought of as traditional or conventional and the color orange is associated with the newer long-life products, there are no hard-and-fast color rules when it comes to engine coolants. All will help keep the cooling system from both overheating and freezing.
Green coolant is your conventional coolant (Ethylene Glycol base) and is the most common type of coolant found. Red coolant is typically has a base of Organic Acid Technology which has a different chemical makeup of green coolant and is designed to be suitable for aluminium radiators.
Antifreeze mixes with water to form a covalent bond to prevent the water from freezing. … Antifreeze Blue is a full concentrate which meets BS6580 and contains the same pure ethylene glycol and anti-corrosive additives as the Red. Its application is for protection for up to a maximum of 2 years.
