Sounds like you have either blown a head gasket, or you have a crack in the head, or in the block.

First step would be to do a compression check on the motor.

SOURCE: 2 problems: disaperring antifreeze & rough idling

I'd hate to break this too you, but if you're both smelling burnt up antifreeze and loosing it at the same time. I'd definitely take a look at the exhaust. Start the motor and let it idle. Watch the exhaust for either water, or steam / whitish smoke. If you're seeing a lot of vapor after the engine is warmed up you're loosing anti-freeze into the engine itself. Most likely due to a blown head gasket or could be as bad as a cracked head (which the windstars were pretty good for), or even the chance of a cracked block.

If it was me, I'd take the van to a good mechanic and have them do a pressure test on the cooling system. If it's loosing pressure then it's definitely a problem. One major overheat can cause a blown head gasket or worse. So, definitely find the cause and problem there.

Also, as for the OBD reading a lean on bank 1, it could be from the O2 sensors reading water vapors in the exaust. It could be clouding a reading and causing such a problem.

Personally, as I've said, I'd run it to a good mechanic who can pressure test your cooling system. It definitely sounds like you have a blown head gasket to me. It could possibly be a cracked head, but more likely towards the gasket. Do the small test I told you with the exhaust. Let it idle and check the exhaust, then even hit the throttle and see if it shows then. If you're smelling anti-freeze out the tailpipe, it's definitely not a good sign.

(Water of course will cause this rough idle as well. It will hurt the combustion process and give you the rough idling.)

I hope this helps, and I hope it's not a major problem. But, I'd definitely find out if it's leaking water into the motor.

SOURCE: heat gauge shows hot , have to add antifreeze although no leak

Very common fault is head gaskets.  causing coolant consumption and bubbles in radiator.  Run vehicle, have a friend accelerate once or twice hard, while you smell exhaust for sweet smell of burning coolant.

SOURCE: 2003 ford taurus smell antifreeze burning &

probably not. put aluminum seal in the cooling system and top off antifreeze. you may need a hose or fitting from where you are decribing the leak. if the leak stops with the sealant you are good to go. otherwise take it to a shop and they will tell you. do not tell them you think it is a head gasket.

Odd smell from engine


If you have been (revving the car/racing/accident/excessive speeding) you will smell something similar to burning oil from the engine, also if it has been more than 10,000kms (6000 mile) since last oil change you should get it serviced.

When i start white smokes comes out why


mine does the same thing.. it is a sign that you are burning oil kiddo..either that or antifreeze is finding its way into the engine through a crack or bad gasket.. check for oil smell and moist soot at the tailpipe, or a sweet smell if antifreeze..now if its a steam like smoke..thats normal byproduct of the burning fuel and goes away once the exhaust pipes and muffler heat up enough to blow out all the condensate water...

Sugary burning smell while driving


That smell is most likely antifreeze. If the smell gets noticeably stronger when you turn on the AC/Heater, it is possible that your "heater coil" has started leaking. You will need the services of a professional if that is the case. Those are very hard to change.

Another possibility is your thermostat is not opening, causing your engine to overheat - steaming some of the coolant (antifreeze)/water mixture out of the system.

And thirdly, it is possible that someone spilled antifreeze on the radiator etc when adding fresh antifreeze - and you smell it after the engine warms up. If your car is not over-heating and you are not having to ad antifreeze/water to the radiator, then just keep driving. The problem will most likely go away.

I hope this is helpful to you. If yes, please take a sec to rate me. Thanks!

There is white smoke coming out the tailpipe no smell of antifreeze


If it doesn't smell like sweet then you most likely got a bad tank of gas. Just to be safe keep an eye on your engine temp. and coolant levels.

My 2002 for taurus runs out of antifreeze every 2 weeks. I don't see a leak anywhere. Also, sometimes I can smell antifreeze when standing in front of the car, near the hood. Is it possible it is...


No, it can't burn it, the engine would seize if it would do that. The antifreeze is lost thru evaporation - this is why you smell it. Check the radiator cap and the overfill tube and bowl.

Smoking out the back and burning smell inside.


check for a cracked head that smoke you see is probably antifreeze coming out of the coolant trench in the block itself or could just be a bad gasket on your head

Have antifreeze leaking in front of car by the front wheels. Smells like antifreeze burning. why?


The anti-freeze smells like it burning because it is coming in contact with your brake pads (will contaminate pads and reduce life and increase stopping distance, exhaust system (most likely cause of burning smell), or some other hot spot on the the engine.

You should resolve this as it will cause over heating as the system can not properly pressurize and reduced coolant level.
