My Chrysler Concorde 2000 3.2? Overheated and melted a hole in the water resivour tank,so we replaced that, it still got hot fast, so we replaced thermostat, then it started making a loud noise it sounds...


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.

Why does my 1994 bmw 318i coolant disappear from expansion tank

Losing anti-freeze cant find leak. dropping to same point every time.


Look at your overflow tank, these caps have a psi rating and if the seal gets old the cap won't hold the pressure and releases small amounts of antifreeze. Sometimes the overflow tank will be a powder looking in spots from the hot water leaking out.

Engine over heats anti freze boils out of over flow


idleing? on the road? are the fans that cool the radiator working? these engine are NOTORIOUS for intake manifold gasket leaks. If it has run low on water you may have engine damage (head gaskets)

Walk through on how to replace a thermostat in a 2001 Jeep grand Cherokee


Jennipherbrr,

1. Make sure the car is cold. Remove the radiator cap (press & turn about 1/4 turn to remove pressure in the system) Once the pressure is bled off you can remove cap and leave it rest on the filler opening.

2. Find the petcock on the radiator (the little valve attached to the radiator. You have to open/turn clockwise to drain the anti-freeze. Drain anti freeze below thermostat housing. About 1/2 to 1 gallon.

3. Have a catch basin for the anti freeze under the car. Remove upper radiator hose from radiator and thermostat housing.

4. Remove thermostat housing from engine block (usually two or three bolts in the thermostat housing). Scrap off ALL old gasket material from engine block. Double check and make sure all gasket material is removed from surface. If not the thermostat housing will leak.

5. Install new gasket with some high temp silicone. Place a couple of dabs on the thermostat housing and gasket (the silicone is used to keep the gasket in place) *MAKE SURE YOU INSTALL the thermostat the same way you took it out. Don't over tighten the thermostat housing bolts.

6. Remove the radiator cap and replace the anti freeze you removed (make sure the anti freeze is clean). Fill the radiator to the top of the filler neck and replace the radiator cap (push and turn the radiator cap to the right- like a pill bottle). Start the car and make sure the temperture guage goes up. The guage pointer should be in the middle of the guage.

7. Check the radiator reservoir for proper anti freeze level. DO NOT OPEN THE RADIATOR CAP WHEN THE CAR IS HOT!!! THE ANTI FREEZE IS HOT AND WILL BURN YOU.

Hope this helps

Anti freze place


there will be a cap on top of your radiator and also a reservoir tank near the firewall that will be a semi transparent container holding either orange or green coolant (do not mix the two colors)

Anti freeze leak


hi are you overheating and are you having to fill it up because it is leaking or were you just toping up and is it coming out of the overflow on the expansion bottle to find a leak that at first appears not to be leaking the best way to find it is to put a pressure tester on it see if the pressure goes down as it will if there is a leak but then you will see it and don,t take the water cooling systems caps off when hot yates210456
