Found this in my radiator.

What do you guys think this is? Installed a brand new flex hose from
NAPA today. Maybe something from the hose? It just seems softer than the hose material. The radiator has only been on for a few miles (75?) because my other one got cracked. Any ideas? Thanks.

And this is what it's on so you know it's a little abused.

 

in..............as in in a fin or INSIDE?

metal, rubber, plastic?

 

Sub'd....that shouldn't be there...

 

I found steel scraps in my fuel pump sock........................the shit u find these days

 

Inside... As in I just put the new return hose on filled her up, ran her for a few minutes and checked the level and there it was in the fill neck.

 

its not simply the rubber from the cap deteroirating is it?

 

deterior.....deteriat...........u kno the word......damn medication

 

Cap looks good, was my first thought, already checked it.

 

Running it again to see if I get any more crap out of it.

 

maybe radiator guts?

 

That was my fear as well

 

I've never dealt with the liquid repair stuff before. Is that what it looks like?

 

Part of Seal from pump?

 

Good news?!?! Second run provided nothing in the full cap.

 

Picture of the hose cause why not.

 

Ziptie mafia approved

 

Bump for any other ideas.

 

My guess would be when the top n bottom of the radiator is assembled if there is a seal where it crimps together and some got shredded of in the crimping process...guessing tho

 

Over the years I have occasionally found junk in the coolant. Pieces of silicone sealant and a random piece of soft plastic that I figured came from a heater core replacement project are two that come to mind. It took a long painful series of flush/backflush evolutions to purge all the silicone.
