Drain and flush your coolant by opening the petcock on the bottom of the radiator and draining it into a container, then filling the coolant system with water and running the engine for a few minutes again. Repeat this process a few times to clean all of the old coolant out, then refill it with a 50/50 mixture of water and coolant.
What causes a leak in the cooling system?
The internal leak may allow some coolant to drain into the engine oil and are caused by a faulty head gasket, loose cylinder head, cracked or wrapped head or cracked engine block. If the leak is very great, it will raise the lubricating oil level in the oil pan. An internal leak may also produce clouds of white vapour in the exhaust gases. 2.
