Turbocharger Coolant Supply Tube: Removal
NOTE:
Whenever the turbocharger air intake system components are removed, always cover the open ports to protect them from debris. It is important that no foreign material enter the system. The turbocharger compressor vanes are susceptible to damage from even small particles. All of the components should be inspected and cleaned, if needed, prior to installation or reassembly.
NOTE:
Special attention needs to be given to the sealing ports for the oil feed, the oil drain, and the coolant lines, on turbocharged engines. The sealing ports must be totally clean and free from O-ring residue, have no damage to the sealing surface and the lines to ensure that there are no leaks or repeat repairs.
