Assembly of hose connections with couplings
  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.
  Caution
The coupling seal may be damaged if the safety fastener is locked when carrying out the assembly. This will cause leaking. Observe the assembly instructions.
