95 Lexus ES300, 245K miles w/ hydraulic radiator fan system. Car runs hot after an extended idle, especially when its over 80-90 degrees outside. At an extended ide, the therm. Gauge gets almost up to the very top and after I get moving again, about up to about 50mph, the therm. Gauge gos back down to normal and stays there, that is, until I im at another red light for a few minutes and then it starts running hot again, its really annoying.
I took my car to a professional radiator mechanic and Ive already replaced the thermostat, flushed the radiator, had the radiator removed and rodded out and there is no apparent water pump leak. There also is no leak in the power steering system since I have been told that the hydraulic fan runs off of the PS system.
My radiator fan does operate, but it for sure does not move as fast as my wife's car which has an electric fan motor, but I have no idea as to what would be deemed an adequate speed for my car. I'm pretty much lost for answers. I hope I've given enough detail, but thats all I can think of at this moment. Thanks again,
have the same problem?
