The old zxr has been getting hotter than normal lately, getting just under red line going to uni (always did this but more often now) and even stayed just above half at 100kms which really worried me. It usually sits right down where it should.
So yesterday i took the radiator cap of and had a look. Water a tad low and looked creamyish. I thought this might just be the stop leak crap i had put in so i drained it all out and ran a bit of vinegar through to try clean it. (hope its not bad, got the idea off here somewhere). It ran beautifully with this, never getting near redline and got fan working properly again![]()
Drained him out then filled with water again to flush out vinegar. Also ran hose through it for a few mins and squirted down most of the hoses.
Now looking at the water that has come out it is still really dirty. Looks like its full of heaps of tiny white/grey/brownish particles and a couple of bigger black ones. Kinda shiny as well. They all seem to sink to the bottom when left for a while.
Now does this seem like its just real scaley and dirty and should i just keep flushing it out or does it seem like something horrible like head gasket/ water pump leaking?
Also is it fine just to use tap water to flush it with? I have distilled water for final fill.
Thanks, ill try get a photo of water if it would help when i get my hands on a cam![]()
