Hi guys. I wrote before about a few drops of fluid that was little reddish brownish I did notise under my car under the area of oil change bolt after leaving the rx330 undriven for one week. I just got a call from my mechanic they pressure tested the cooling system and removed the under shield no sign of any leak was there. People talked before about leaking coolant from the the engine block heater cover. I am confused now. Some help will be appreciated.

 

Reddish brownish? Sure it's not tranny fluid? The block heater cover is up beside where the oil filter mounts. It's easy to see, and easy to see if it's leaking as well.

 

Reddish brown would be tranny fluid, but i dont think it is your tranny. I think it is your steering rack. Power steering uses tranny fluid. Check the boot by looking in frm behind your front passenger tire.this is common issue on these cars.
