  Note
t  The supercharger air system should not leak
t  The flexible hose sleeves and the other turbocharger air system hoses must be free from oil and grease before the assembly.
t  Apply a lubricant for rubbers free from silicone and oil on the leaking surface and on the joint ring. Do not use lubricant products containing silicone or oil.
t  Replace the joint rings where damaged.
t  On replacing the joint ring, place it on the turbocharger hose groove and check that the joint rings cover the entire groove perimeter to prevent damage.
t  Secure all hose connections with the correct hose clips (same as original equipment) → Parts catalogue.
t  To fix the turbocharger hoses to their connection sleeves safely, if already used clamps are used, their bolt threads should be sprayed with an anti-corrosion spray before the assembly.
