Lexdesert Posted June 5, 2011 Share Posted June 5, 2011 Hi, Vehicle is an LS400, it has a hydraulic operated cooling fan, however time comes when my fan speeds extra ordinary, I have changed the fan oil/hydraulic fluids, it never helped, time comes when it speeds out of hand, even when the car engine is in idle. How do I fix this? where I am, i can not access a lexus dealership. The car doesn't have heating problems, just a speeding fan, I have had this vehicle for 3 years, it started doing that last week, someone had mentioned that a part called solenoid valve could be the problem, however I failed to locate this part, he said its the one that controls the speed/pressure of hydraulic flow; causing a stable speed towards the fan, so how do I fix this problem, somebody please help, pleeeeeese!!! Here am on my own! Quote Link to comment Share on other sites More sharing options...
