Removed radiator about 4-5 days ago and cleaned it with HC acid. Didnt get all of it out. Put antifreeze in and have been driving around sense then. Checked it today and I made soap. I flushed it and it came out like dawn dish soap. It was yellowish, but not like oil in the water. More flushing tuesday. But I guess the HC acid mixed with the antifreeze and broke it down and pretty much made soap. I thought this was weird, but I do know that my radiator insides are much cleaner.

 

Cool! Sounds like it worked really good.

 

Never thought of using HC acid to clean the rad out but sounds like it worked pretty good!

 

Alright, 2 "stupid" questions.

1. Does the radiator go into the engine through the top or bottom hose (Im thinking bottom)

2. On the overflow it doesnt have "hot" or "cold" it has the "add" and the "full" and Ive read on diffrent sites to put it on the "add" and ive also read to put it up to "full" so which is it?

 

The flow is from top to bottom. Why fight gravity! This picture may help.


mark.

 

Thanks, makes sense not to fight gravity, already so much work spinning that fan.

 

Found the picture of it

 

Hmm sounds like it worked well. I would flush it pretty good to get all that acid out, and replace the hoses. I imagine that wouldn't be good for them.
