After diagnosing my overheating problem which seemed to have been caused by a busted valve in my radiator cap, I am now needing a new one. I have read a few topics here and there all over the Internet with advantages and disadvantages, but most have been heresay and there aren't many facts to back up what people have posted about in their statements especially when it comes to Subaru's.
In order for me to make a decision, and to benefit others that are in a similar situation, what exactly are the advantages and disadvantages of having the 1.3 bar radiator cap over the 1.1 bar one in my stock Liberty 3.0R SpecB?
Please provide as many facts as possible. I do understand that various people have opinions on STi products especially with regards to their price, but try and keep your posts neutral and without bias.
