Apparently my husband hit a rock when driving our car up the mountain to put it in the garage to get it out of the hail. Car seemed fine, drove it into town and back no problems. On the 4th we drove up the canyon to meet our son. On the way the car overheated badly. On arrival there was a deluge of water and antifreeze coming by the hose. After that the gauge said we did not need to add water but you would have to be an idiot to believe that. We added cool water from the river slowly, let the car cool and then started home. Long story short we got home, the radiator problem seems to be handled, but if we turn the wheel to take a curve or turn around the car dies. Power steering problem perhaps? Or????
the hose was NEVER repaired?...of course it was. Think that if "the car dies" must probably be an electrical concern...seeing as you went through some water or ice do suspect that you've got a weak chassis/ground connection...take that other end of the black cable (Not the clampy side) but the 1/0 cable end and wirebrush the lug with a coarse brush and the chassis as well...if it starts okay we won't worry about the ground connection near the alternator but this one has to be a 300 cold cranking amp connection. With a NEW battery and solid connection to the chassis, you will be okay electrically (the ECU will be happy and not issue poor instructions)~
Also, in the rustle-tussle of the coolant hose the main coil wire or coil packs are not connected all the way, high tension wires are weak or one of your motor mounts is loose or rubber comprimized to where this high-voltage gets a little too close to ground...should put a block of wood and a floor jack under there, jack up the motor a 1/2 inch and see if daylight is comin' between the rubber and mount...you probably need a motor mount or two~
Assuming your system is hydraulic (takes power steering fluid) you have an idle speed up switch that responds to fluid pressure in the hoses. When you turn the steering wheel this increases the pressure of the fluid and activates the switch. The idle speed increases about 50 RPMs to compensate for the added load and prevent stalling. Perhaps the plug on the switch got damaged from the extreme heat of the engine and/or scalding hot coolant when it overheated. Check your high pressure power steering hose for this switch. It should have a 2 way electrical connector plugged onto it. HTH. -Jim
