How to Know When Radiator Requires Replacement

automobileglobe.comThe car radiator is one of the most frequently repaired components among cars that have been used over a long period. Radiator-related issues could be due to many reasons and some of them can be resolved through a basic, auto-repair regimen. However, sometimes a complete overhaul or a radiator replacement is required. Changing a radiator is an expensive proposition so it’s vital to identify whether it actually needs replacement. The need for changing a radiator can be confirmed through some small, easy-to-do inspection techniques explained below.

  1. Establishing Radiator Rusting

Rusting can occur along the outside and inside of the radiator. Often, when metal flakes start appearing on the radiator’s body, extreme rusting is indicated. However, interior rusting is more damaging. The first sign of excessive, internal rusting is the color of the radiator fluid — the coolant. The coolant should retain the color of its packaged form. If the coolant seems too watery and there is floating debris, radiator rusting is seen. If the coolant has a distinct, sludge-like appearance, it implies small particles of weathered rust, along with coolant debris, is being sucked into the coolant lines. This form of damage to the radiator is actually irreversible and changing the radiator is the only solution. Reducing rusting to the outside doesn’t . However, if some spots of external rusting have given way to rusting along the core of the radiator, a replacement eventually gets necessary.

  1. How to Establish Radiator Leakage

Sticky coolant debris most times disrupts the coolant flow. This creates excessive pressure along the radiator valves, causing them to leak. This is the most frequent cause of leakage among vehicle radiators. In order to check radiator leakage, the coolant has to be flushed-out. Never do this inspection with a running vehicle. You should approach the coolant section when the engine hasn’t been used for at least three-to-four hours. The basic configuration of most automobile radiators is similar. It comprise of two radiator hoses along with two coolant lines. It is best to drain out the coolant by disengaging the lower coolant line. Channel the disengaged line into a dried plastic jug. Be sure to properly dispose of radiator waste properly. After the coolant has been emptied, flush the radiator with cold water. With the use of  a garden hose to apply pressurized water. This helps to weather away the coolant debris. Ideally, you should put the hose in the radiator cap for at least 15 minutes to allow thorough cleaning. Withdraw the hose and let all the water drip-away. Now, refill the collected coolant. If you discover that the radiator is still leaking, it implies that any type of repair won’t last for very long. Changing the radiator is recommended in this situation.

  1. Establishing an Underperforming Coolant Action

It should be known that the affectivity of the coolant is dictated by the condition of the radiator. If your vehicle heats-up repeatedly, an underperforming radiator could be the reason. If this occurs even after repeated coolant and water replacement, a faulty radiator is almost guaranteed. Overheating results to quick depletion of the coolant. Here, the coolant leaks in the form of steam. Conventional garage repairs don’t work in this scenario. Leak sealers can only offer temporary relief. Such overheated engines need a radiator replacement.
