Exploding radiator, clog?

[illinois_erik]

looks like it..except I think theyre hex bolts instead of regular. I noticed them when I was poking around back up under there doing the motor mount and exhaust

thanks man, Im putting in a new rad, hoses and tstat in.. Im going to drain the system fill with white vinegar and let sit over nite to dissolve the scale then flush, this helps a lot

you dont know how many people come into my work looking for that stuff, i always tell them "its like putting a band aid on a bullet hole"

flushed out the block and the system multiple times, got the new radiator and t-stat in no problem, everything seems to be much better. all that sediment is gone.
