It's fun to carry over a big project from last year! 6:40 Main topic: GR/GV/VAB power steering problems The pump hums when driven hard, then crashes if driven continuously, and if driven further, the assist cuts out. The pump has different part numbers for the GR/GV STI and SpecC, while the VAB pump is the same as the SpecC pump for the GR/GV. The difference between these pumps is the fluid capacity and discharge rate. Is the SpecC better? Not really. Hard driving causes it to heat up and foam, resulting in a drop in oil pressure. It can also melt plastic parts, causing breakdowns. The stock oil does not have a high heat resistance. Change it frequently with an ester-based oil with high heat resistance. Avoid continuous driving and allow it to cool. A power steering cooler is only effective if it's installed in front of the radiator (not compatible with BP/BL systems). Avoid continuous driving even with the cooler installed. It's best to change lubricants more frequently than recommended by the manufacturer. 8:00 PM Q&A begins. The power steering of the GR/GV is prone to oil leaks not only from the pump but also from the gearbox. If it breaks, we can rebuild it. 11:30 PM KM1 accepts inquiries via email. Please include your address, name, vehicle identification number, and details. 12:20 AM When oil gets hot, additives deteriorate, oil seals deteriorate, and metal parts wear out. As a guideline, change your power steering oil every year. Adjust the change interval depending on how it feels after a change. Subaru's power steering fluid is, honestly... Choose an ester-based fluid with a high heat resistance. What about electric power steering? Assistance will stop if it gets too hot. Accumulate knowledge and experience to avoid damaging your car. 29:20 PM Mechanic knowledge and skill levels vary. In the past, hydraulic fluid didn't deteriorate and was often left unchangeable. Nowadays, regular oil changes are part of preventative maintenance. Is smoking a defining characteristic of Subaru fans? Should you be careful not to add too much additive to your air conditioner? Actually, maybe not? Let's do an experiment. 36:00 Are Subaru fans characterized by mecha enthusiasts, Gundam fans, and Start Worth fans? Is it okay to have no power steering? Hard driving is extremely difficult! Even city driving is difficult! Oil doesn't compress, so adding too much can cause breakdowns. Air conditioning is a different story. 40:00 Chit-chat & Q&A It's fun to be able to do your own car maintenance. Ogata-san likes mecha works from the era of the first Gundam. New air conditioning gas is good. A back-and-forth exchange of comments between viewers who support Tomino's "Massacre" and viewers who support power steering and ABC. 49:50 What kind of power steering hose is good? Chit-chat 51:25 Next time, we'll dig deeper into O2 sensors. Ogata-san isn't a racer, he just enjoys going to mini circuits with everyone. 54:40 Please subscribe, like, and refer a friend! 55:10 The end. #Subaru #Subaru #Impreza #GRB #GVB #VAB #WRX #STI #PowerSteering #PowerSteeringPump #PowerSteeringGearbox #PowerSteeringOilLeak #PowerSteeringNoise #PowerSteeringNotWorking #Omoste #PowerSteeringPumpNoise #PowerSteeringFluid #PowerSteeringFluidLeak #DexronIII #HeatResistantPowerSteeringFluid #NoContinuousDriving #DestructiveTesting #PowerSteeringOilTemperature #PowerSteeringHighPressureHose #PowerSteeringOilCooler #OilCooler #HeatResistantRepair #PumpNoise #MeowingMoreThanThePump #Kitten? #STIPump #SpecCPump
