      you may be able to unthread that plastic drain valve completely and poke something in there to clear it out. Probably packed with sludge. Usually not a promising sign for whatever thats worth.

        I can pull the lower hose, yeah. I'm starting to think $60 at my local (trusted) shop for a full professional flush & fill ain't a bad deal...

          how do the radiator fins on the inside around the cap look?
          if they are crusty, just buy a new radiator and hoses, if it's the original radiator, it's prob gonna start leaking after a flush

            No that's not terrible at all. The coolant itself is the expensive part because you've gotta buy so damn much of it. 60 for the green stuff and for someone to flush it for you is good.

              This is damn near guaranteed to fuck your radiator, if it's got that much sludge and shit in it. A new radiator is 81 dollars from rock auto. Use the discount code in the site news section for 5% off.

                Not bad actually, just did an initial drain tonight. There's definitely some rusty sludge, but not that much actually. Fins look okay. Shiny metal for the most part. The coolant itself is nasty. Looks like coffee. I'll do this for a few nights and see where I'm at. Some parts may be in order...

                  Alright, here's the deal. I've been draining and refilling the radiator for about a week now, for a total of 6 times. Water's coming out pretty darn clean after 40 miles with periods of the heat blowing full blast. Not crystal clear, but tolerable. I know at this point buying a new rad and hoses would be great, and although $80 for one is extremely reasonable, I really can't foot it at the moment. Inside the rad looks okay. Not great, but not nasty. There's just a bit of real pitting and corrosion, but mostly, the fins look like someone took a dump in it--just that same old thin layer of crap that feels/looks like clay. Running the hose in it makes it look fine again until the next drain.

                  I read so many conflicting things about cleaners/flushers. Are any of them worth using? Prestone flush? What about weird "home remedies" like vinegar, baking soda, laundry detergent, or CLR? Common sense tells me to stay away from that junk...but, what's the consensus? I obviously want to strike a balance between something that's effective but won't harm my gaskets. If it's a good idea to stay away from any additive, I'll just run with semi-dirty coolant until I can afford a new rad. But then, at that point, wouldn't I want some kind of flush anyway, so my new rad doesn't fill with shit?

                  Sorry for the novel...

                    If you call this a novel, then the really long story thread must be an encyclopedia.

                    Personally I have no problem using the Prestone flush (that's what I used the last couple of times I flushed cars). Just be aware that using a flush may open leaks that are clogged with crap. It's a small chance, but it may happen. Other then that, I'd say flush it.

                      Flush it with the Prestone stuff, then put coolant in. You won't have done it any harm by flushing out the rusty crap. The cooling system may not be completely pristine, but hey anything is better than nothing.
