possibly the water pump or a bad hose
There might be a leak in the water pump, or in the radiator. Maybe even check the radiator hoses for cracks and leaks.
Water pump out, ruptured tank on radiator, or head gasket blown probably in that order.
Could be the intake manifold gaskets are leaking.
try following the hoses from the anti freeze tank you should find your problem...
if it rear air and heat it could be the line carring the antifreeze tho the back heater core.
Depends on where its leaking from. Could be a clamp hasn't been tightened enough. If its coming from elsewhere, it could be a leaking head gasket. Look for coolant in the oil or coming out the tail pipe.
smell of antifreeze and no visable leaks usually indicates that the heater core needs replacing
change your antifreeze fill cap.
Could be a few things. Does it leak antifreeze? if so, fix the part that leaks. If not, you could have coolant mixing with oil inside the engine, which burns it. check your spark plugs. If they are white, you are probably burning antifreeze - fix immediately. your exhaust will smell "sweet" as well if you are burning antifreeze.
I had the same problem with my 5.9L and it was the timing chain housing leaking antifreeze. It could also be a freeze plug maybe but that is rare. Hope this helps
Some people say that the smell of hot antifreeze smells like mold. It could be possible you are smelling the antifreeze from the engine.
The antifreeze is not coming from your transaxle actually it is usually from your intake ,running down the trans case. This is a very common problem that 3.1,3.4 lt have is leaks at the intake.You have to replace your intake seals. But check under your throttle body ass. to make sure its the intake and not the heater hose connection that runs underthere.
