To keep the water in the cooling system from boiling or freezing, the water is mixed with coolant or antifreeze. Car Smarts: Most coolants contain about 95 percent ethylene glycol, a chemical that ...

Under normal conditions, a 50/50 mix of water and coolant is preferred for most vehicles. If the day is extremely hot or cold, a higher proportion of coolant/antifreeze may be necessary.

How To Check And Top Up Your Radiator Coolant First, get the right radiator fluid, meaning you have to find the right antifreeze and mix it with water in the right ratio - usually 50/50 - before ...

5. Protect Against Freezing: In cold climates, the antifreeze component of the coolant prevents the liquid from freezing, which can cause significant damage to the engine and cooling system.

Thus, antifreeze is an element of coolant, with it typically comprising around 50% of the mixture . Coolant meant for lower-temperature climates tends to include higher percentages of antifreeze.

Top Tech Antifreeze & Coolant Tester The Top Tech is part of the Euro Car Parts range, and uses a similar floating glass tube to the Draper 61794.

Too high a concentrate of antifreeze can lower the boiling point of the coolant. Aluminum was a tad high at 6 ppm (parts per million), but well below the maximum of 10 ppm.

In fact, if pure antifreeze-coolant is used in a car’s cooling system, the system loses about 35 percent of the heat-transfer capabilities it otherwise would have when antifreeze is mixed with ...

Armed with a coolant tester, which cost around £10-15, you’ll be able to test your car’s antifreeze throughout the year, reducing the likelihood of a costly breakdown.

As the coolant is directly responsible for keeping the engine at a reasonable temperature, it becomes crucial to monitor things. After all, knowing how much coolant your car can hold and what type of ...

Coolant leaks aren’t always easy to find, as air blowing through the front of the car can spread coolant all over, and that means the puddle you see on the ground may not be directly under the leak.

There is no engine built to run water as coolant, except the ones built before coolant was invented in 1926/28. To avoid unnecessary costs and disruptions, it would be best that you use what the ...
