I opened my Mom's radiator cap (89 3.1 grandprix) today to check it , it had some sorta baby $hit brown crap on the underside of the cap , not alot but enough and some on the inside of the radiator , but not any in the fluid that I could see . the fluid did not look real clean . Im going to flush it this weekend . But , what is this baby $hit brown crapola ? I saw it in my radiator when I pulled it from the boneyard ! I flushed it real good . My radiator has been ok sence .

 

Is it maybe some rust?

Maybe leftover rad sealant?

 

Might possibly be a blown head gasket. Was there coolant in the oil in the last oil change?

 

Thanx for the help man .
No , No coolant in the oil . I changed the oil not to long ago to . Im just ganna flush the radiator real good . It's only been flushed one time sence we have had the car . We have had it sence 89 . So thats prabably what it is huh ? Just really crappy dirty fluid that needs to be flushed out and re-freshed !

 

Yeah always a good idea to freshen it up.

 

I HAVE HAD SOME OF THAT BROWN STUFF IN MY COOLANT RESERVOIR. IT NEEDS TO BE FLUSHED. YOU WILL BE OKAY.
