Lmy 05 aviator with 20000 miles overdrive light on dash came on as did the check transmission. after taking it into the dealer a solinoid was replaced in transmission. A day later the aviator did the same thing. The mechanic said the wiring harness was the problem but had to order one. NOw he has to replace a heas bolt. What the heck is going on?

SOURCE: Check steering assist warning

could be a pinched power steering hose or you may need to replace the power steering unit itself. may cost as little as 5 bucks for the hoses or as much as 75 or so for the unit

It means something is wrong with it. Start with fluid level check, idling , warm fluid, in park....

SOURCE: 2002 Lincoln LS overheating

The cooling fan on the LS-V8 is hydraulic yes. But it also has a pressure switch on the pump that drives the fan. It is controlled by the temperature sensor. All these things must be taken into account. But the whining sound my lead me to believe that the pump is either low on fluid or is wearing out. The fluid the fan pump uses is the same as the power steering pump container so check it first. The same thing happened to my wife's Lincoln. I replaced the fan as well because everybody told me to do that but it didn't work. I found out that the fan is just a hydraulic motor in reverse it only spins as fast as the pump makes it spin and that is controlled by the temp. sensors. When the engine get's hotter the pressure goes up and the fan spins faster. This adds more power to the engine when it's running cooler because the fan doesn't have to spin at max speed. So good luck. I hope this has solved your problem.
