Do you have white smoke coming out of the tail pipe? If so you have a combustion leakage-meaning the coolant is being burn in the combustion chamber in order for this to happen-it is caused by a blown headgasket, crack head/engine block.

You might want to have the tests below performed.

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat,Pressure test the Rad. cap,Clogged radiator,Fan clutch,Radiator electrical fan,collaspe hoses,water pump.

Need repair manual for your year/make/model see link below

Thank You I took it to a garage and they put in a new radiator, it seems to be doing fine however I noticed that I still have antifreeze going into my overflow is this normal? I just picked it up today.
And I am not overheating any longer, but I now have a low coolant light coming on Is this normal?
Thank You Once Again Betty V.
