Hi,
my 2011 Lexus gx460 is losing coolant. It reaches the L line after about 1000 miles, I don't see any fluid under the car when I park. Any idea what could be causing this or maybe this is within spec for a car with almost 120,000 miles on it.

Thanks!

Have you looked around the radiator fan area where water pump is? Pop the engine cover off and shine light into areas around the intake plenum.

Also might need to get down on ground and look up on rear area of motor.

It is pink in color and will turn into a crusty pink like cotton candy.

Unlikely but possibly a blown head gasket with an internal leak. The coolant would be burning off. Do you see any white smoke when you start the car?
