Below is a Real Fix from Mitchell 1′s new SureTrack® expert information source. These documented issues from actual shop repair orders demonstrate how SureTrack can help you correct issues that are not easily diagnosed using OEM information alone. SureTrack is currently available free in our ProDemand product. Hydraulics, Cool? The cooling fan on this Lincoln LS is common because it’s hydraulically powered. Since this fan is hydraulic, oil pressure dictates the speed of the fan. When the solenoid controlling the flow of pressure fails, the fan no longer operates properly and the vehicle is prone to overheating. Don’t let the P1299 trouble code get you heated and use this Real Fix to solve the overheating fault. Auto Repair Manuals Get everything you need to diagnose and repair your car problems today.
