TECHNICAL SERVICE BULLETIN
Reference Number(s): XT303-13, Date of Issue: June, 2004
JAGUAR:2002 MY-ON X-TYPE
VIN:C00001-ON

Related Ref Number(s): SECTION XT303, NO. 13, XT303-13
ARTICLE BEGINNING
Issue
Some 2002 MY-ON X-TYPE vehicles may exhibit driveability/hesitation concerns. Customers may also complain about a hissing noise from under the hood.
The concern may be caused by a vacuum leak from the O-ring seal on the Intake Manifold Tuning (IMT) valve.
The O-ring is now available separately to avoid the need to replace the entire valve.
Action
In case of a customer complaint of the above condition check whether the Intake Manifold Tuning (IMT) valve O-ring seal has failed. If so, DO NOT replace the IMT valve since the O-ring seal is now a serviceable item. Follow the workshop procedure outlined below.
Workshop Procedure
Installing a new upper IMT valve O-ring seal.
Open hood and install fender protection covers.
Disconnect the IMT valve electrical connector and reposition harness.
Remove the IMT valve securing bolts and displace and remove the IMT valve from the intake manifold. Remove and discard the O-ring seal (Fig. 1 ).
