The radiator is one of the most frequently repaired parts in long-term cars. Problems related to the radiator can be caused by a variety of reasons, some of which can be solved by basic automatic repair solutions. However, sometimes the radiator needs to be overhauled or replaced. Replacing the Toyota Prado radiator is an expensive proposal, so it is important to determine whether the Toyota Prado really needs to replace the radiator. You can check by the following operations.
1. Check the radiator for rust
Rust may occur inside and outside the Toyota Prado radiator. Usually, when metal flakes start to appear on the radiator, it indicates extreme rust. However, internal rust is more destructive. The first sign of excessive internal rust is the color of the radiator fluid (coolant).
If the coolant seems to be too watery and there is floating debris, then the radiator is rusty. If the coolant shows a clear sludge-like appearance, it means that fine weathered rust particles and coolant debris will be sucked into the coolant pipeline. This damage to the radiator is irreversible, and replacing the radiator is the only solution.
2. Check the radiator for leaks
Sticky coolant fragments often interrupt the flow of coolant. This creates excessive pressure on the radiator hoses, causing them to leak, which is the most common cause of leaks in Toyota Prado radiators. In order to check the leakage of the radiator, the coolant needs to be flushed, but this check should not be performed on a moving car.
Loosen the lower hose to drain the coolant, and put the loosened hose directly into a dry plastic pot to ensure proper disposal of radiator waste. After draining the coolant, flush the radiator with cold water. Pull out the hose, let all the water drip off, and refill the collected coolant. If it is found that the radiator is still leaking, in this case, it is recommended to replace the radiator.
3. Check the coolant
If your Toyota Prado repeatedly heats up, the radiator may be performing poorly. If this happens even after repeatedly replacing the coolant and water, it is almost guaranteed that the Toyota Prado radiator is malfunctioning. Overheating can cause the coolant to run out quickly. In this case, regular garage repairs do not work. The leaked sealant can only provide temporary relief. This overheated engine requires a radiator replacement.
