Adding water to your engine coolant is generally not a good idea. Antifreeze is designed to protect your engine from freezing or overheating, and adding water can dilute the solution and make it less effective. Additionally, water can rust and corrode your engine components. If you need to add fluid to your coolant, it’s best to use distilled water.

If you notice one or more of the above symptoms, your radiator may be clogged and in need of repair.

A coolant flush is a process whereby all the old coolant is removed from your system and replaced with new antifreeze. This is important because it ensures that your radiator is working at its optimal level and minimizes the risk of overheating and a high-temperature gauge.

If your heater core is clogged, you can clean it out by flushing water or air through it. By doing so, the grime and dirt that’s causing the clog will come out through the inlet hose. Now, insert a water hose into the outlet hose. If you have access to an air compressor, you can use that to push out the coolant and grime.

How do I know if my radiator has water circulating?

One way to check for proper coolant circulation is to check the upper and lower radiator hoses. The upper radiator hose should be hot, around 190–200 °F. The safest and most accurate way to get this temperature reading is with an infrared thermometer. If the upper radiator hose is not hot, then there may be a problem with the water pump or the thermostat.

After draining the system, your mechanic will wash out the area near the water pump. This is because there are a lot of small seals in this area that can crack and cause leaks. Additionally, washing out this area will remove any debris that may have collected in the cooling system. After another drain, your mechanic will wash out the heater core. This will ensure that the system is free of any contaminants that could cause problems down the line.
