Yikes! That is some horrible sludge... time to flush and replace everything that is destroyed.

That's ugly was somebody running straight water in that thing?

Last time I saw sedimentation like that it was because someone was mixing dexcool with regular antifreeze

By the way it looks I'd be thinking that someone was trying to plug a leak with some type of fix it crap and they ran straight water in it and never changed it out.

No. That's liquefied water jackets. Lots of flushing with oxalate to clean that out. Unless it's thick like butterscotch pudding. My Blazer radiator looked like that when the oil cooler let go inside the radiator.

Thanks I think, I hope you don't think I was naive enough to be serious with my post.....on second thought, don't answer that. .....:cool:

Yuck. Time for an old school chemical acid flush. I personally would drive around for a week with the acid in there. Then lots of fresh water flushing. Once clean, a 50/50 mix of distilled water and anti freeze "should" be good as new unless the rust was plugging some leaks. The water pump may leak too just because. Do yourself a favor and get some litmus paper. Test the water you are using. A PH of 8 is ideal. Above 10 and all rusting ceases but you risk foaming. Below 6 and you get rusting. PH can be adjusted easily with common household items. EDIT: Here is a post I made about using Cascade dish washer machine soap. I did it on a Jeep and the stuff worked well. Maybe too well as the 17 year old radiator later leaked. Luckily is was under $100 to replace. https://gbodyforum.com/threads/cascade-as-radiator-flush.58549/

I did a prestone radiator flush. Drained the Rusty water, added the flush with water, drove it nearly 50 miles to work and back, drained it (looked just the like first drain, Rusty) topped it with water, drained it (again it looked the same from the first time, Rusty) and the rust water won't stop. After the last drain I just topped it with 50/50 antifreeze. Will get a new radiator later if I don't sell the car before. I gotta start planning for the elky. Thanks guys, God bless you all.
