SOURCE: My radiator cap is leaking antifreeze. I noticed

Not being a smart-alec here but, remove your cap and look to see if there is any flat spots on the filler area. If not, you just need to replace the cap.

SOURCE: leak around fitting

Take the fitting loose and check for damaged threads in case it's a cross threading issue. I would suggest screwing the fitting in by hand to insure threads are properly engaged, on any situation.
If the threads are damaged you might have to rework them by "tracing" with a die on the male portion, or "tapping" the female portion.
If they're not damaged, try to screw the fitting by hand as far as you can, then tighten with a wrench.
You might also try teflon plumbers tape if needed.
Sometimes a simple thing can become such a pain... Good luck!

Adding coolant little few times a month no leaks notice could it be degas cap. Head gasket going bad

It could be the radiator cap, a small leak in the radiator, or a small head gasket leak.
Many auto stores or shops can test the cap.
If there is a leak on the radiator, it will often cause a stain which you could look for.
If there is a leak into a cylinder, it will often cause a difference in the colour of the spark plug.

Why is my car leaking water out of the radiator cap only when the heat is off but when the heat is on it don't leak ???

turning the heat on lowers the temperature of the water running through the engine which in turn lowers the pressure in the radiator

After it runs for awhile it starts leaking antifreeze coolant

If you can't see any obvious leaks around rubber hoses or radiator, it could be leaking though the engine block gasket into engine. Or even escaping through the rad cap when hot, leaking as steam slowly. Try putting a new radiator cap on (rad cap). As a quick fix, put Radweld solution into coolant. Any auto shop has it.

My radiator is leaking from the top. Is it just the seal on top or do I have to replace the radiator?

v6 or 4cyl?? Is it leaking from the radiator cap (4cyl only)?? If its not leaking from the cap and leaking from the radiator itself, whole radiator needs replacement.

I have a 1996 Honda civic, it spits out water at the radiator after running for 10 minutes. What can I do?

If the radiator is leaking, put a bottle of radiator stop leak in it,fill it up the rest of the way with water, tighten cap, and run in idle for 15 to 30 minutes. If the leak is severe or one bottle doesn't work, use two bottles of stop leak and run for 35 minutes.

If it's the radiator cap that's leaking, replace the cap with a new one. Also check to make sure there are no loose cooling hoses.

Safety first: Use extreme caution to never remove the radiator cap when the engine is hot, severe burns from escaping hot water could result.

2003 saturn ion adding antifreeze every 2 weeks cannot find leak

There should be a radiator cap as it controls what goes into the overfill tank. You might consider replacing it. If there are no leaks in the radiator or hoses, there are only 3 places the coolant can go (water pump leak, blown gasket, or out throught the radiator cap). Hope its the cap because that's the cheapest. Good luck!

Where is the radiator cap located on 2001 Saturn SW2?

Your system does not have a cap on the radiator. It is a 'sealed system' with the reservoir holding pressure. This is not so much an 'overflow' tank like some systems, but an expansion tank.

You can add the stop leak directly into the tank.
