For removal of Spiral Cable and AirBag Module, refer to RS-16.¼ Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. Spiral cable and wiring harnesses (except “SEAT BEAT PRE-TENSIONER”) cov-ered with yellow insulation either just before the harness connectors or on the complete harness,are related to the SRS.SEM164FAEM080LIQUID GASKET APPLICATION PROCEDURENGLC00671. Use a scraper to remove all traces of old liquid gasket frommating surfaces and grooves. Also, completely clean any oilfrom these areas.2. Apply a continuous bead of liquid gasket to mating surfaces.(Use Genuine RTV Silicone Sealant Part No. 999 MP-A7007or equivalent.)¼ For oil pan, be sure liquid gasket diameter is 3.5 to 4.5 mm(0.138 to 0.177 in).¼ For areas except oil pan, be sure liquid gasket diameter is 2.0to 3.0 mm (0.079 to 0.118 in).3. Apply liquid gasket around the inner side of bolt holes (unlessotherwise specified).4. Assembly should be done within 5 minutes after coating.5. Wait at least 30 minutes before refilling engine oil and enginecoolant.GIMAEMECFECLMTATTFPDAXSUBRSTRSBTHASCELIDXENGINE LUBRICATION SYSTEMKA24DEPrecautionsLC-3 PreparationSPECIAL SERVICE TOOLS=NGLC0068The actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here.Tool number(Kent-Moore No.)Tool nameDescription(J34301-C)Oil pressure gauge set1: (J34301-1)Oil pressure gauge2: (J34301-2)Hoses3: (J34298)Adapter4: (J34282-1)Adapter5: (790-301-1230-A)60° adapter6: (J34301-15)Square socketAAT896Measuring oil pressureMaximum measuring range:1,379 kPa (14 kg/cm2, 200 psi)WS39930000( — )Tube presserNT052Pressing the tube of liquid gasketKV10115801(J38956)Oil filter wrenchNT362Removing oil filterENGINE LUBRICATION SYSTEMKA24DEPreparationLC-4 Lubrication CircuitNGLC0069ALC1161.
