radiator trouble
took the truck for a short ride and when i came back there was a hissing noise coming from the front. popped the hood and right where the rad cap goes was where it was coming from. (my rad is the sealed rad and the over flow is where the cap goes) after i opened the cap and let the remaining air out i noticed a drip on the pass side. gonna bet its the radiator which was replaced before i bought the truck. would the overflow tank not venting it right cause the rad to take a shit? i know im gonna have to get a new one along with a new rad but i wanna make sure this problem doesnt happen again. TIA

heres a pic of my fill tank

Here's exactly what is happening. Leak started shortly after I opened the rad cap. Posting from my phone so I hope the link works

Found this too. Exactly what's happening

1.) coolant leak - seems to be comming from the overflow cap as seen in vid

2.) took cap off of coolant resevoir and ran engin -The engine was still a little warm when I did this. After I started the engine the return tube imediately began squirting coolant back into the resevoir (thermistat open?). There was a little steam rising from the resevoir, but I didn't get any bubbles or gysers when I raced the engine.

3.) looked for leak - Traces around pass side end tank. Have not crawled under there yet

I would take it to a professional radiator shop & get a diagnosis
There are a couple checks that can be done quickly
it may be just a hose collapsing or something else simple

ok. took the truck apart. it is the radiator leaking. right at the end tank on the pass side. it looked like the water pump had a drip or 2 but im not sure if thats where it came from. i reinstalled the rad and filled it with water and didnt see any drips by the pump but i didnt really get under it. i dont want to re install a new rad and have this happen again. what could it be?
