When to top up the overflow tank on a radiator?
Q2 not really – if you have low fluid in the radiator then you need to top it up. The fluid does not change in volume very much between cold and hot – the overflow tank is to deal with fluid escaping when the pressure and temperature cause fluid to get past the radiator cap seal.
What are the signs of a bad coolant overflow tank?
Here are four of the most common signs of a bad radiator overflow tank. If the radiator coolant overflow tank is damaged or cracked, then you can expect coolant fluid to leak out of it. Sometimes cracks will form on the overflow tank if it is too old and worn out.
Is there such a thing as an overflow tank?
