I think I have a block in my radiator, that moves through the radiator. My temp gauge (aftermarket) goes up...I turn on the heat or accellerate little and the temp goes down. It's like the block (possibly mineral deposit) is moving its way through my radiator.

I only use distilled water and coolant, however, the previous owner may have used tap water. This is why I believe it maybe a small mineral build up or deposit floating its way through my radiator.

Is there a way to fix this without replacing the radiator. (i.e. Would flushing in a couple of times possible fix this problem)?

Suggestion/Help - THANX!!!

 

just flush your system with regular water and refile it. it may just be air though so you should bleed it first.

 

lol i work at a dealer and guess what we put in your radiator. Tap water! yep it dosnt do anything tap water isnt gona clog your radiator if it was id have more then 1000 cars coming back for over heating problems
