Engine light came on, and I had a feeling it was the radiator. I flushed the radiator and replaced with top of the line coolant no water. 3 days later wife was driving to work and temp gauge light came on and whistleing sound, then steam from the vents and then under hood. I picked the car up, added water and drove fine. any ideas, still have not really driven it anywhere worried about the problem. Thermostat ? when I flushed it particals got stuck in hose line ? not sure any ideas ?

Re: Steam came in from vents and high pitch whistle
Start the enginemake sure the radiator is full with the cap oon tightly and open the hood and let the car idle in the driveway untl it starts to team, this way you can locate where the steam is actually coming from.
when it is overheating is there white smoke coming out of the tail pipe?
if there is this is a good sign thatyou have a blown ead gasket.
the other thing that couldbe causing this over heating is a plugged catalytic converte.
to rule out whether it is the themostat sticking or not. remove the thermostat from the car put it in a pot of boiling water on the kitchen stove and see if it opens or not. the boiling water will make the thermostat open if it is working properley. Be sure to pay attention as to which way the thermostat is pointing when you remove it so when you put it or a new one back in that it is facing the correct direction. if it is not facing the rite direction it will not open and cause the car to over heat.

The whistling noise is steam. The problem is you never attacked the source of the problem. What you need to do now is drain your radiator completely at opening T-spicket at the bottom of the radiator. While you drain with engine off, run your water hose on top, to flush out the radiator. Then run to the Auto store and buy "radiator flush" -- follow directions. After flushing out the radiator flush, close the T-spicket, and fill with NEW anti-freeze. By enough to fill to the very top. Mix the anti-freeze with water per instructions to your environmental weather.
Buy a new radiator cap which could have caused the problem in the first place by not allowing the correct pressure to blow off. Being a 2000 car is a little early for radiator problems, but an incorrect anti-freeze solution causes radiators to fail prematurely.. Better to have more than less because anti-freeze keeps the radiator from corroding.
Your radiator never cooled the water sufficiently, and boiled much of the water out, hence it got so hot that it would melt the water tank. The Thermostat could well have been the cause because it got corroded from the inept ant-freeze mixture. Did you find rust on the Thermostat ? If so it was the case. If not the radiator has lost cooling either by low water or the cores have become plugged up, in that case you will need a new radiator. See if the flush loosens the rust within the cores before buying an expensive radiator. Check the water hoses if leaking cooling. Run the car allow the engine to become hot before accepting that your water hoses are fine. Because heat expand everything, and may not leak until after the expansion.
this sounds odd but mine did this when i replaced the wipers. it seems the design of the wiper frame was making a whistle at higher speeds. the freestar wipers are exposed on the window cowl and not hidden so they endure the winds at high speed. it is worth a shot.
If u have issues with heatting may be this will help.
1- If the carpet under
the heater core is damp, or if antifreeze vapor or steam is coming
through the vents, the heater core is leaking.Remove it and install a new unit (most radiator shops will not repair a leaking heater core.
1 - If the air coming out of the heater vents isn't hot, the problem could stem from any of the following causes:
The thermostat is stuck open, previnting the engine
coolant from warming enough to carry heat to the heater core. Replace
There is a blockage in the system, Preventing the
flow of coolant through heater core. Feel both heater hoses the
firewall. They should be hot.if one of them is cold, there is an
obstruction in one of the hoses or in the heater core,or the heater
control valve is shut. Detach the hoses and back flush the heater core
with a water hose. If the heater core is clear but circulation is
impeded, remove the two hoses and flush them out with a water hose.
If flushing fails to remove the blockage from the heater core, the coremust replaced.
It means that the pre heat is in operation.It is a system that burns diesel to create heat to warm up engine quicker so that warm air comes into car sooner.The smoke is the exhaust gasses from the system and normally the whistleing and smoke stops when engine reaches running temperature or on short journeys approx 1 minute after engine is turned off
During summer when no heat is required and air con is on cooling it should not light even when starting from cold
I have the same problem like yours but what i did is to replace the alternator and now its so quite no more high pitched sound. You may used belt stress fluid but its only last for few seconds then sound comes again. I replaced it with refurbish part alternator.My sienna 2005.
