alright so I had an issue with oil in the coolant on my CBR project. There was zero coolant in the oil. I removed the waterpump and it looked perfect with no coolant coming from the weep hole, shaft and seals perfect. So I reinstalled that and moved on to the oil cooler which sits in a bath of coolant on the front of the engine block. The seals were bad, orings nasty, so they were all replaced with new OEM Honda parts. Oh no Mr Bill I also cleaned out the hoses and anything I could reach. When I was cleaning it, it seemed that brake cleaner was about the only stuff that would dissolve the chocolate milk. I know there is more of this in the radiator and engine block. I plan to replace the rad for other reasons so I don't want to spend a bunch of time and energy to get it boiled. Will repeated flushings work? How about that Prestone rad flush? I will probably just run straight tap water for the flushing process I see no reason to use coolant for a short couple hour ride to get everything nice and hot. Any other advice?
