ive been searching googles with no luck and forums as well.

most of the forums say jsut blast that sht out with pressure washer or garden hose.
but the problem is kinda blowing up your heater core in the process if its clogged.

i dont know what type of stop leak was used in my car but theres little doubt that it was used.because the coolant was brown and i have deposits in the coolant pipes.


heres some pictures( as some of you saw tem in integra forum already)
im just posting here so people be more aware of this crap and what it does to your coolant lines.


FITV valve was completely clogged

 

New heater core, new rad, flush the engine, you will probably need a chemical flush to get rid of that crap.
I know of no way to get it out of the core and rad properly. 94

 

will the prestone coolant flush or coolant cleaner do the job?

 

Maybe, try some on the spots you can get to and see if it will dissolve it. 94
