LEXUS GS 300 RADIATOR PROBLEM

1999 Lexus GS 300 • 140 miles

This car is over heating. The termostart is good, radiator does not leak but water drops at the rear end of undercarriage. The car gets clouded, the water return hose from the engine is not heated during the process. Is my water pump working? What could be the problem?

Does it overheat at highway speeds? Have you flushed the radiator? Is the cooling fan working?

I have done all of the above. I have a feeling it is leaking within the heater core. I am going to re-route the line to cut off water supply to the core and see if it continues. It heats up even when am doing 75 mph.
