Completion! The strengthening cylinder head bolt which job years 1999 November this time is used (the photograph left) Don't you think? the right side is different genuine products thickness With this in the midst of sale As for genuine volt/bolt to extend installing the metal gasket easily, when you use high revolution with such as circuit, the phenomenon which the gasket comes out with the extension of volt/bolt happens well enough When the gasket comes out, spitting happens to ラジエター With the polo polo and the air bubble increase early condition Coming out completely, the stripe uninformed ドバッ and the ラジエター liquid start blowing with accelerator on ラジエターキャップ is "when being hot, opens also the giving ぐ れ"
