SSM 479672019-06-06. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Some 2013-2019 vehicles equipped with a EVDC air conditioning (A/C) compressor may exhibit poor A/C performance/improper climate function and/or a diagnostic trouble code (DTC) P06A0 in the powertrain control module (PCM). To support the proper diagnosis of this compressor, the EVDC control valve tester has been developed and is available from Rotunda (339-EVDC100). A tester has been provided to each U.S. dealership free of charge with shipments completed 19-Apr-2019 (reference EFC07013 on FMCDealer.com). This tester will help reduce the potential for misdiagnosis and unnecessary compressor replacement. Make sure that this tester is used for warranty repairs and document the test results in the Technician Comments field. Refer to the Rotunda catalog for a video and user manual which provide detailed operating instructions.
TSB19-21402019-06-05. Service bulletin. ENGINE AND ENGINE COOLING. Some 2018-2019 F-150 and Mustang vehicles equipped with a 5.0L engine built on or before 30-Apr-2019 may exhibit a chirping type noise from the upper engine front cover area at warm or hot idle. This noise may sound similar to a front engine accessory drive (FEAD) chirp noise. This may be due to the primary timing chain tensioner oil pressure relief valve. To correct the condition, replace the primary timing chain tensioners. Follow the Service Procedure.
TSB19-21442019-06-05. Service bulletin. ENGINE. Some 2018-2019 F-150 and Mustang vehicles equipped with a 5.0L engine may exhibit a light to moderate knocking type noise at idle (600-700 RPM) that is sometimes described as a quiet diesel type sound. The noise is usually more prominent on the passenger side of the vehicle toward the rear of the engine. As the engine comes up to operating temperature, the noise level increases slightly. This noise is not detrimental to engine function and has no short or long term effects on engine durability. This an operating characteristic of the 5.0L engine and no repairs should be attempted. Refer to the Service Procedure
SSM 479112019-05-07. Service bulletin. ENGINE. SSM 47911 - 2018-2019 F-150/Mustang - 5.0L - Chirping Noise From Engine Compartment At Idle Some 2018-2019 F-150 and Mustang vehicles equipped with a 5.0L engine may exhibit a chirping type noise from the upper right side of the engine at a warm or hot idle. This noise may sound similar to a front engine accessory drive (FEAD) chirp noise. If the noise persists with the FEAD belt removed and is isolated to the front cover area, this noise may be due to the primary timing chain tensioner. This noise will not result in any engine durability concerns. Do not attempt any repairs at this time. Engineering is investigating, monitor OASIS for updates.
