Check under the input shaft of the water pump. If there is a colored streak, it's probably leaking there.
Leaking head gasket could allow coolant to pass out the exhaust. There would be a sweet smell at the tail pipe.
Had a problem like this once. Have the radiator pressure tested and look for leaks. Could be coming from the weep hole as stated above. Generally if antifreeze is in the exhaust the tail pipe will blow white smoke. My problem was a frost plug had a small rust crack in it allowing the coolant to escape and burn off the exhaust. Same problem as what you are experiencing. Drive the car get it hot and open the hood to see if you can smell the antifreeze. If you can there is a leak somewhere. A bad radiator cap will do this also.
It could be the radiator, the hoses, a leaking coolant tank or the water pump.
If coolant is leaking from a car it means that your radiator has a hole in it. If this is not fixed the car will over heat.
Check radiator hose, leaking water pump, look for hole in radiator, leaking coolant bottle or leaking seals.
Having to add collant & coolant leaking from the hose.
is coolant leaking from engine?or is it leaking from water pump and running down engine and appears to leak from engine
If the hoses are all tight, Then the radiator must be leaking. REPLACE RADIATOR
If you are only leaking coolant into the exhaust and use the type with copper in it, then yes, it should stop the leak. If coolant is getting into the oil or exhaust is getting into the radiator then no, none of them will do any good.
You may have a bad radiator cap.
Check the radiator hoses. The coolant is either leaking out of the new radiator, or it is coming from a radiator hose. The water pump may be leaking. Hose clamps may be loose.
It could be a number of things, a clogged radiator,bad thermostat,low coolant, hoses leaking coolant, radiator fan not working,or a leaking head gasket. Hope this helps you.
It is leaking coolant or the radiator cap is faulty.
Your radiator is probably leaking transmission fluid into your coolant. Trans cooler is built into the radiator. Replace the radiator.
