Signs you need a new radiator Your temperature gauge is getting hot. If the temperature gauge needle is constantly working on the hotter end, then there could be a problem. A rusted or corroded radiator is a sure sign that it needs to be replaced. Rust can weaken metal and cause holes to form in the radiator, causing coolant to leak.
A rusted radiator is also more likely to leak in other areas, so it's best to replace it before it kills engine machinery. You can also take your car to Natrad and we will not only check the radiator and coolant, but also the entire cooling system. Mike Patton Auto Group, serving Stovall, Georgia, can be your savior when it comes to radiator repair and replacement. However, if detected early, sludge formation on radiators can often be eliminated by flushing the radiator, a relatively quick and cost-effective procedure that can save the engine and your hip pocket.
Refilling the radiator with new coolant will also allow the car's cooling system to operate at maximum efficiency, lubricating the water pump, improving performance and extending the life of the cooling system and the entire engine. In addition, Natrad is Australia's only national network of radiator repair and replacement specialists that can offer a true 3-year national warranty backed by the manufacturer. If any problems are diagnosed, we will determine if your car's radiator needs maintenance, replacement, or repair and discuss it with you before starting work. The most common causes of radiator problems include corrosion, hose deterioration, thermostat or water pump failure, blockages and obstructions, “eddy current”, physical damage (such as stones hitting the radiator grill), and leaks in the radiator core.
