What are the causes of internal coolant leakage in the Edge?
2 Answers
Edge internal coolant leakage causes are as follows: Radiator damage: Prolonged radiator use leads to internal scale and harmful substance buildup, causing corrosion damage that results in coolant leakage. Poor sealing: Loose connections at the interfaces between the cooling system's coolant reservoir and radiator can cause coolant leakage. Pipe aging: Aged and cracked coolant pipes lead to leakage. Coolant is dyed for easy identification (typically green, blue or pink with viscous texture), making leaks more noticeable.
I've been driving the Edge for several years, and internal coolant leaks are usually caused by issues in the cooling system. The most common problems are aging or loose hoses and connections, as rubber hoses can crack and leak over time. A failed water pump seal is another frequent cause, especially in high-mileage vehicles where the pump shaft seal wears out and leads to leakage. Additionally, if the engine head gasket is burnt out, coolant may seep into the cylinders or oil passages, causing unstable engine temperature or emulsified oil. I've also encountered radiator leaks due to cracks, which worsen on bumpy roads. Another issue is a poorly sealed filler cap, which increases system pressure and forces coolant out. In short, internal leaks are common, so it's essential to regularly inspect cooling system components to prevent engine overheating and failure.
