My coolant has been dropping slowly in my reservoir.
I have found the radiator to be leaking which I replaced.
I replaced the hoses and clamps and confirmed its not leaking from that location.
I have changed the radiator cap, and confirmed it not leaking from that location.
I have checked the passenger side to confirm the heater core was not leaking.

I will be changing the thermostat but was told it might be unlikely.
I am left with the waterpump which does not show any signs of leaking on the floor nor when I have it running on the car ramp.
There is a squeak from maybe an idler pulley in the early morning which goes away in less than 10 mins of driving the car.
No coolant in the fuel. No white smoke, no loss of acceleration. Spark plugs look ok (no white crusty build up) NO sweet smell from the exhaust.

I read that on some cars the coolant can be leaking into the intake manifold?
Is this true for the 2005 ES?
thanks

Yes there is a hose under the intake that likes to leak, 16261-20010

Is the 2003 and the 2005 the same setup?
I found this video on you tube

Same deal as that video.

Have you checked for coolant in the oil or trans fluid?
