Im trying to change the antifreeze but it has only one cap on the plastic and not on the raditor would that be a prob when change

Get your self some ramps pull the inspection cover off the botton on the car follow the fat hose up to where your themostat is remove hose and empty your block for antifreeze pull off old thermostat remove and replace then on passenger side radiator un screw plastic butter fly antifreeze will come out of there take bottle where antifreeze is and clean take cap off and clean catch all the antifreeze in bottles then you can flush system out drain water out same way when replacing antifreeze you need to open upper heater hose to burp system 50% 50% works fine unless you live here witch I run 75% anti 25% water I also own a 2000 subaru outback loaded

change raditor cap see that helps ,u dont see bubbles in coolent do you it could have bad headgasket or cracked head

Antifreeze goes into the radiator. There should be both a radiator cap and also an overflow reservior. Top off the radiator and fill the reservoir to the "max fill" line. NOTE: DO NOT remove the radiator cap when the engine is warm. You'll get burned

YOU NEED TO CHECK YOUR COILENT AND RADITOR SYSTEM YOU HAVE TO CHANGE THE ANTIFREEZE ABOUT EVERY 5 YEARS OR SO YOU HAVE CLOGGED RADITOR AND HEATER COREGO GET SOME RADITATOR FLUSH PUT IT IN THE RADITATOR LET VEHICLE IDLE READ DERICTIONS ON CAN DRAIN ANTIFREEZE REFILL WITH WATER AND DO IT AGAIN THEN PUT NEW ANTIFREEZE IN USE A HOSE AND RUN LOTS OF WATER THROUGH SYSTEM IN EVERY DERICTION YOU CAN THIS MEANS THE HEATER CORE LINES TO GOOD LUCK PIER.J

replace your radiator cap.Cap is not holding pressure letting antifreeze escape past it to overflow then on the ground.When enough antifreeze has escaped engine starts to overheat.

these newer cars use a surge tank, located on the fender well, ddrain old coolant from radiator, you can go further by doing a full flush, conect any hoses you may have taken off, fill the surge tank as you would fill any normal radiator

At the bottom of the radiator there is a plastic knob this is the petcock drain plug it can be hard to see and turn so you may need to jack up the front of the car a little to crawl under the front and look at the bottom of the radiator but if you can reach it from the top and turn it with a pair of pliers do so that way this will allow you to drain the radiator, remove the radiator cap if it has one to allow air to pass through radiator, if it has no radiator cap remove the cap on the radiator expansion reserve tank, after all antifreeze is drained turn petcock drain plug back in till tight then refill raidiator with 50% water 50% anti freeze mixture, start car and top off antifreeze run the car or drive for ten minutes then top off antifreeze.

you may have a water pump that is starting to fail. Look for the water pump that's driven by the fan belt. look at the housing of the water pump there is a relief hole that they drill in the casting and when the pump begins to fail it will drip out this hole. If that's where your leak is, it's time to change the pump.

Not only the cap, but you have to find the drain. They are usually put in the most difficult places. After ten years consider having your system flushed, it'll be good for your radiator. Take the car to a jiffy-lube type place and they will change your oil for you too. The Taurus is a good car, treat it right and it will give you good service.
