Can anyone help... my 2007 GS 300 has developed a screech from the front of the engine, it seems to be coming from the water pump and pulley area. Has anyone had this happen or any ideas as to what may be causing it. Also will it be safe to use as I am unable to get to Lexus until Tuesday. many thanks

Hi Chris welcome to LOC.

The most likely cause of a screeching noise from the area you are talking about is a worn or loose serpentine belt "fan belt". Squirting some water on the ribbed side of the belt will usually stop the noise for a short while "a minute or so", but long enough to prove if this is the problem. Tensioning the belt should remove the screeching noise, but get it checked out for ware.

As for continuing to use the car short journeys should be ok, but I would not advise motorway use as if the belt brakes the engine will rapidly overheat.
