Crawl under there and see where it is leaking from, if it's old I would just pay the 10 bucks and change the lower rad hose

Re: Radiator leak

That or it may be dripping out of the weep hole on the pump and hitting other under body components on the way down.

Or this telling you it's time to change a water pump out. Pretty easy job as long as a EFFIN bolt don't break off :/

Kinda confused but is it a small leak or more of a problem like running hot and boiling over after just a short drive?

Re: Radiator leak

Is it coming from the overflow tube?

If so you may have a blown head gasket, cracked block or head.

If it was head head gasket or block wouldn't it leak from the start the motor runs instead of just when it gets hot also oil isn't discolored

Two warning signs of blown head gaskets could show a little water in your oil, you can check your dip stick and u would see a sheen, another way is removing your radiator cap and looking down. You can often see debris of a head gasket floating

just a thought. if the cap doesnt seal properly it will let the water boil easier. when your system stays pressurized it is harder to boil the water. but without the required pressure the water will boil faster. if this makes sense?

Yeah I believe the cap has to have a 10-12# seal. Not 100% sure on that number though
