Coolant Line/Hose: All Technical Service Bulletins
Cooling System - Underhood Gurgling Noises

NO: 25-24
DATE: 04-25-2006
MODEL/ YEAR: S80 2003
XC90 2003
SUBJECT Gurgling or Groaning Noise from the Hose under the Intake Manifold
REFERENCE: VIDA SB 25-0038

DESCRIPTION:
A gurgling or groaning type of sound from the front of the engine could be caused by the hose under the intake manifold or the hollow screw that
attaches the banjo fitting to the manifold. To prevent having to replace the entire hose assembly, a new hose kit is available as a replacement part. There
is also an improved hollow screw. This TNN describes how to replace the hose.

SERVICE:
Replace the hose and hollow screw under the intake manifold to correct the noise concern.

Information:

The illustration displays the new replacement part with hollow screw and copper washers.
