Stop leak is a temporary fix. I don't recommend it. Tighten the clamps on the hoses going into the raditor.
I had a similar problem and ended up replacing both the lines and the radiator.
Have it checked out soon and don't let the engine overheat!
To change the antifreeze on a 2003 Saturn Ion-3, locate the drain plug on the bottom of the radiator. Drain the liquid into a pan before refilling it.
you got a gas line leaking. get it checked soon
Are you sure that isn't antifreeze and if so that would indicate the radiator is defective. There is a transmission oil cooler in the radiator.
Most likely a leak in the heater core, should be on the passenger side under the dash.
Don't complain; if the engine isn't leaking coolant that just means everything is sealed up properly.
The drain is located on the lower right of the radiator and is opened or closed with a screwdriver. It is a plastic plug that does not come out. The surge tank cap must be open for the antifreeze to drain.
you did'nt get enough antifreeze in the system ther is probably air in it
Make sure the radiator fan is working. Your thermostat is broken.
The 1996 Saturn more likely has a blown head gasket. The gaskets will give this problem. If the head is in doubt it can be checked for warpage.
Sometomes it is hard to get all of the oil out of the cooling system. However the place that replaced the engine should flush the cooling system until it is clean. Also if your car has an engine oil cooler , it could be the cooler in the radiator and not have been the engine in the first place.
