The kits can be used on just about any make and model car or truck. One way to flush a radiator is described here and requires little more than emptying the coolant, running water and radiator flush solution through it to clear out any gunk that may be clogging the system, and then running water through it repeatedly until clean, allowing the engine to run and cool each time.Īnother method of flushing the cooling system is to purchase a radiator flush kit for about $5 at a nearby auto supply store. The cost to flush a radiator yourself is minimal. Flushing a Radiator with or without a Radiator Flush Kit Any signs of debris, rust or corrosion indicate the need for a flush. If there is no leak, the coolant is failing at its job and needs to be replaced.Ī clogged radiator is a serious issue and should also be addressed with a radiator flush to remove the contaminants preventing it from allowing air to remove heat from the passing coolant. The most common cause of this is loss of fluid due to a leak.
The same holds true for flushing a cooling system: Certain symptoms may indicate a flush is in order despite how much time has elapsed since the last one.Īn overheating radiator is the most obvious sign. Your dentist may tell you to brush your teeth every morning and night, but you know if you’ve just eaten peanut brittle or caramel, you might want to brush your teeth midday too. Why the Cooling System May Require More Frequent Flushing

The two primary actions an automobile owner can take to ensure their cooling system is working is to keep the radiator full of coolant-a 50/50 mix of antifreeze and water-and to flush the radiator periodically, depending on the manufacturer’s recommendation in the owner’s manual. Absent coolant, an engine will overheat and damage could begin to occur in less than a minute. But when maintenance is necessary, it needs to be done quickly. Today’s automobile cooling system works incredibly efficiently with relatively little upkeep as the pump pushes the coolant through the system continuously when the engine is running. Later they discovered that a more effective coolant included ethylene glycol, which raised the boiling point and lowered the freezing point of water, allowing it to remain fluid over 212 degrees Fahrenheit and under 32 degrees Fahrenheit. What these inventors devised was a system that pumped water in a circuit around and through the various heated elements, absorbing the heat and radiating it into the air through a box at the front of the engine compartment.
