FORD:
1998 CONTOUR
ISSUE:
Some SVT Contours may exhibit a "hooting" or "moaning" noise when the A/C is on and the engine is operating between 2200-3200 rpms. This may be due to resonance in the air by-pass valve and Idle Air Control (IAC) tube assembly.
ACTION:
Replace the air by-pass valve, hose assembly and gasket. The new valve and hose should reduce the possibility of a resonance noise in the air by-pass system. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1. Remove and discard the air by-pass valve and retain the bolts.
2. Loosen the hose clamp. Remove and discard the hose and tube assembly.
3. Install the new hose and tighten the hose clamp.
4. Install the new Air By-pass Valve (XS2Z-9F715-BA) and Air By-pass Inlet Hose (F8RZ-9H308-AA). Be sure to install a new Gasket (E83Z.9F670-A) between the new air by-pass valve and intake manifold.
