Why won't it start?

if it is an automatic ( make and model omitted in question) there is every chance that it is transmission oil from a burst cooler in the radiator tank. The fix is a new radiator or and air to air cooler core fitted in front of the radiator. If the engine is a diesel or an engine that has a sump oil cooler then the oil core has burst allowing engine oil into the radiator vial the coolant system. It may be from a failing head gasket where the oil hole to the rocker gear is leaking across to a water jacket

Head gaskit Re: Jeff

Water pump/thermostat.

Check the engine for a Crank angle sensor. if there is one fitted :)

Replace it and re-tune the computer and ignition.

you radiator is shot and you need to get the trans flushed out as soon as possible before it burns the trans up. The trans uses the radiator as a cooler and the internal cooling line has ruptured. How did it burst out? from where? What burst?

1.If your radiator burst replace. 2.With the car COOL, open the radiator cap or overflow and fill it.3.Leaving the cap off, start the car and let it warm up as you keep the radiator topped off. 4.Once it wont take anymore and your sure the car is completely warmed up, reinstall the cap.5.Everything else your gonna have to hurry on or your car may start overheating. Grab the top hose and squeeze it. If you can't almost grab it till it closes then you have a bad thermostat. Replace it, if you have any doubts, pull it off the car and boil it inside in a pan of water, you should see the spring move and open the plate.6.If thats not it check your water pump for flow,bearings, and belt condition.7.Also check all your fluids for antifreeze contamination, mainly the oil, as this can be a sign of a blown head gasket which is very common on these years of Gallants. REMEMBER your cooling system cools by building pressures of over 300 psi, and any flaws in your radiator during a overheat will blow! Hope this helps ya buddy! Shannon(Shizzo)

Is the water tank the windshield washer fluid or the radiator overflow tank??

If it is the washer fluid tank, fill it with "below 32F" type fluid. If it is the radiator over flow tank, it would appear to me that the radiator fluid is too watered down or weak and is not freeze resistant. The radiator fluid should be 50/50 mix of Prestone or other make of radiator fluid and water. This is to save your engine and radiator from bursting. Ice takes up move volume that water (this is why Ice floats on water). Inside of a pipe, radiator or engine block, this can be devisating. You could crack your radiator or engine block. Hopefully who ever serviced your car last used the correct fluid. You might want to get this checked before more damage happens to your car.

Hope this helps.

One of three things has happened, in order of most to least likely:
1. Your lower radiator hose has burst and needs replaced. (Assuming your lower radiator hose is on the driver's side of the radiator on that vehicle)
2. Your radiator has been damaged and needs replaced
3. Your radiator drain **** is loose or missing (assuming it's on the drivers side of the radiator)

You will need to investigate closer to see where your issue lies. It should be easy to spot a damaged hose.

Good luck

check your glow plugs they may be damaged or dirty
