COOLANT, or as you may know it, antifreeze, is used to help your car engine maintain an even temperature when faced with extreme changes from hot to cold weather.
Coolants come in different colors to indicate their use and the difference in their production formula, for example you will find red or pink coolants.
There are some coolants that you can mix, but you should always check with the antifreeze company beforehand.
Companies tend to use different chemicals and some coolants should not be mixed for this reason.
Red and pink coolants are considered compatible and can be mixed together.
But if you don’t have to, you should refrain from doing it.
The red coolant can shorten the life of the pink coolant, resulting in less effect when using it.
Still, you don’t have to worry about the mixture damaging your cooling system.
The pink coolant is an organic acid OAT technology.
It contains the following substances:
Pink coolant is considered more durable, while red coolant is more “conventional”.
It still lasts a long time but not as long as the pink.
The red is an IAT – Inorganic Acid Technology – and consists of the following substances:
To find out which paint coolant to use, consult your vehicle manual for information on maintaining your vehicle.
You will find other color coolants like green, blue, yellow and orange.
Older cars used blue and green coolants called IAT – Inorganic Additive Technology.
These could last two years or 60,000 miles.
But as automotive manufacturing has evolved so has coolants and you will find that the OATs or a mix of OAT and IAT called hybrids last longer.
Modern cars – probably made after 1998 – use these and they can last five years or 100,000 miles.
Recently, another coolant based solely on OAT has also been developed.
It can last up to 10 years or 300,000 miles.
