SOURCE: Radiator blockage?

I believe you have a head gasket blown or a cracked head. When you start it up COLD with the cap off, it would push water out immediately. Fill it with plain water and try this. It might not be a bad idea to perform a pressure test too. Also check for antifreeze in the oil. It will get milky looking and might even be over full. If this happens after warm-up, you may just have a plugged radiator. Have it professionally cleaned. The water pump vanes could also possibly be corroded off and it's not effectively displacing coolant. Hope this helps.

SOURCE: where do you fill radiator on 02 taurus ses?

YES. But dont overfill it. Slowly add coolant to the low full line and let it run a while, like 10 minutes. if the level goes down fill it to the full line. After it cools for 30 minutes recheck the level and add as needed.

Please explain reserve cooling system 2005 Ford escape 2.3 engine.

When water gets heated, pressure builds up in the radiator and water vapor is sent to the reserve tank.
And vapor dilutes into the water in the reserve tank.
When the engine cools down, in the radiator, vacuum builds up. To fill the vacuum water is pull from the reserve tank.
If vacuum leaks from radiator, gasket, etc., reserved tank won't able to function

Did you refill the radiator and reserve tank after the work? If not, the radiator will suck water in from the reserve tank to top the radiator off.

Refilling radiator

Before you add coolant always make sure that the engine is cool never add coolant to a hot engine.Next remove the radiator cap and fill it to the top with a 50/50 mixture of coolant and water.After you have filled the radiator with the coolant water mixture put the radiator cap back on and then fill the reserve tank to the cold level mark on the side of the bottle

does the radiator fans turn on ??

I have a 99 Mercury Sable Wagon that keeps boiling the radiator fluid out of the reserve tank. The temp gauge isn't reading hot, though. Any suggestions? Thanks.

Sounds to me like a blown head gasket. Even if your vehicle is not warmed up, if your reserve tank is boiling fluid out of it when the engine is cool, it's most likely losing compression from it all going to your reserve tank. And thats why it's fluids coming out of your reserve tank. BUT, if your radiator is clogged then the same thing could happen. So i would start out cheap before you have to replace a HG.

Why is all the fluid staying in reserve tank-none

The line to the reserve tank to the radiator could be plugged up or you have a loose radiator cap or a bad seal causing the tank to hold whats in it. The coolant system is a pressurized system and if a seal is bad or a line is plugged you will experience this problem for the pressure is not there to take whats needed from the tank to deploy in the coolant system

I have a 2001 chevy Malibu. Have problems with

Due to the complexity of the newer cars on the raod today!! what you are experiencing is Normal!!! since the coolant systems on the newer cars run at such a higher pressure and a high Rpm the reserve tank which has it's on drain hose for excessive overflow from the radiator allows the extra high pressure release from the radiator to back flow to the reserve tank and then out the reserve tank overflow hose on to the raod
