# Service bulletin 15\-0073 A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10058059 - Published by NHTSA: 2015\-07\-28 - Manufacturer's number: 15\-0073 - Manufacturer's date: 2015\-05\-08 - NHTSA component: ENGINE AND ENGINE COOLING:COOLING SYSTEM:HOSES/LINES/PIPING/FITTINGS ## NHTSA's summary FORD 2015 F\-150, MUSTANG: BULLETIN INFORMATION INVOLVING CERTAIN FORD VEHICLES EQUIPPED WITH A 5.0L DUAL OVERHEAD CAMSHAFT ENGINE MAY EXPERIENCE HAVING COOLANT LEAK CAUSED BY A HEATER OUTLET HOSE WHICH HAVE BECOME DISCONNECTED AT THE HEATER OUTLET TUBE ON THE COOLANT PUMP. \*LJ ## The document No address for NHTSA's copy can be built for this communication. Ask the dealer for it by the manufacturer's number. ## Components Engine, Cooling system ## Vehicles listed - 2015 FORD F\-150 - 2015 FORD MUSTANG ## Recalls for the same vehicles and component - [16V779000](/recalls/nhtsa/16V779000.md), 2016-10-26: ENGINE AND ENGINE COOLING:COOLING SYSTEM:HOSES/LINES/PIPING/FITTINGS ## Other bulletins for the same vehicles and component - [TSB 22\-2089](/bulletins/10209031.md), 2022-03-15, Service bulletin: ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN; UNKNOWN OR OTHER. Some 2015\-2022 F\-150, 2017\-2022 F\-Super Duty and 2018\-2022 Expedition/Navigator vehicles may exhibit poor air conditioning \(A/C\) performance, loss of airflow and/or engine cooling fans running continuously from high A/C pressures. This concern may be from the evaporator freezing up due to the evaporator temperature sensor being biased. To correct the condition, follow the Service Procedure steps to replace the evaporator temperature sensor. - [TSB 21\-2250](/bulletins/10201612.md), 2021-09-30, Service bulletin: EQUIPMENT:APPLIANCE:AIR CONDITIONER; ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN. Some 2015\-2020 F\-150, 2017\-2020 Super Duty and 2018\-2020 Expedition/Navigator vehicles may exhibit poor air conditioning \(A/C\) performance, loss of airflow and/or engine cooling fans running continuously from high A/C pressures. This concern may be from the evaporator freezing up due to the evaporator temperature sensor being biased. To correct the condition, follow the Service Procedure steps to replace the evaporator temperature sensor. - [SSM 47791](/bulletins/10156875.md), 2019-04-08, Service bulletin: ENGINE AND ENGINE COOLING:COOLING SYSTEM; ELECTRICAL SYSTEM. Some 2015\-2019 F150/Edge, 2016\-2018 MKX, 2019 Nautilus and 2017\-2019 Fusion/Continental vehicles equipped with a 2.7L engine may exhibit a malfunction indicator lamp \(MIL\) and/or wrench lamp with diagnostic trouble codes \(DTCs\) P0116, P0117, P0118, P0119, P0217, P0330, P1026, and/or P130D. This may be due to a engine coolant temperature \(ECT\) sensor connector which is not fully seated or damaged wiring between connectors C1064 and C1047 for F150 and C1016 and C1168 for Edge/MKX/Nautilus/Fusion/Continental vehicles. ECT sensors should not be replaced if damaged wiring is found at or near these connectors. For claiming, use causal part 12A699 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual. - [SSM 46085](/bulletins/10109070.md), 2017-08-01, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE \(EGR VALVE\); ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:COOLING SYSTEM:HOSES/LINES/PIPING/FITTINGS; ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:COOLING SYSTEM:RADIATOR ASSEMBLY; ENGINE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE \(PCV\); ENGINE AND ENGINE COOLING:COOLING SYSTEM; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:ENGINE:DIESEL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:BELTS AND ASSOCIATED PULLEYS; ENGINE AND ENGINE COOLING:ENGINE; ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN. The Powertrain Control/Emissions Diagnosis \(PC/ED\) manual has been revised for diagnosing electronic throttle bodies \(ETBs\). The ETC\_ACT and ETC\_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes \(DTCs\) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.
