Hello, Just need to replace my radiator cap but there is no stamp on it as to what pound it is. Wondering if anyone has that number. Went to the local auto parts store and the guy gave me a seven lb cap but then online I was seeing 13 and 18 so want to be sure. Ever since i bought it, there was no coolant recovery tank so looking to get that jnstalled and working again but this caps seals are all disintegrsted. Thanks in advance.
