What should coolant look like

One is a visual check. If it looks milky or cloudy, or has particulates floating in it, flush the system, Hagerty reports. But the best way is to measure its acidity, using either litmus paper or a voltage meter, Family Handyman reports.

If the meter reads above 0. Replacing your coolant is fairly straightforward, Advanced Auto Parts reports. First, open the radiator and coolant reservoir caps. After letting it cool, drain the flush compound, replace it with water, and run the same steps again.

If you realize you have a coolant leak, always clean it up quickly, as it is extremely toxic to both people and pets. Another way you might notice that you have a coolant leak is by watching your temperature gauge.

All of your car engine parts have to endure a lot of wear and extreme temperatures, and it takes a toll in different ways. Corrosion within the radiator is one of the leading reasons that coolant leaks. As the tubes get older and weaker, you may get sediment or debris inside that causes a leak.

The sealing gasket between the tank and the radiator can also wear out, and that could lead to a leak. The places where they connect to the radiator, water pump and heater core all become vulnerable to leaks as a result. The radiator cap may be small, but it has a big job. The radiator is extremely pressurized, and the cap is responsible for creating a tight seal that keeps the cooling system at the right pressure. However, with time, its seal can deteriorate or the spring might start to wear out, which can allow coolant to escape.
