That video is showing the inverter cooling fluid for the hybrid system. Mine does the same thing and the dealer tells me it’s normal. Currently my M hybrid is in getting the heater core replaced, for the first time at 64k miles. Should I be saving for this repair again or would regular flushes help?FilltheFetters wrote: ↑Sun Jan 19, 2020 10:48 pmThe original dealer is still around just further away and in a larger city, so I went to the local dealership with the expectation that any sort of warranty/goodwill work would be funded by Infiniti not the specific dealership, but At this point I intend to visit the dealership that installed the part. I am not all that optimistic after my last visit, they noted an unusual amount of debris in the coolant but could not suggest a source, and they also implied a new heater core would be a guaranteed solution whereas replacing the automatic transmission fluid warmer instead could fix it as well but with less certainty. I could not follow their reasoning at the time as the last heater core failed so quickly, it seemed like they were guaranteeing their profit margins and not actually solving the problem.
You will have to forgive my ignorance on this, while looking for the sediment I noticed the coolant in my reservoir appeared to be quite turbulent. I can't say I have paid much attention to it before but it caught my eye and I can't seem find a answer elsewhere online.

Is this to be expected? Are there multiple connections to a reservoir and if so does coolant usually flow through the tank and/or would this just be caused by vibrations from the engine idling? I looked at a couple of our other vehicles while they idled and the coolant appears to be still by comparison.

I've only seen them on a few diesels, but I can't imagine it would hurt anything to try it. My question would be, why are the cores clogging in the first place? The reason we see far fewer clogged cores than the old days is that there's no heater control valve on modern cars to stop the flow and allow crud in the core to ossify over the summer. So it seems unlikely to me that chronic clogging could be from particulates settling out in the core. It seems more likely to me that there's some chemical or electrolytic process going on with the core materials that's causing internal corrosion. If one of y'all get a core replaced, ask for the old part and give it a bandsaw job, I'd love to see some pics and they might tell a story. One thing you might consider trying is a sacrificial marine zinc someplace in the cooling system. They sell zinc "fingers" that you can adapt to the drain plug and I've installed a few over the years for people with unexplained corrosion issues. Nothing complicated about it other than routing a ground wire to the finger once you modify the plug.FilltheFetters wrote: ↑Sun Jul 18, 2021 1:35 pmI came across a post on reddit about someone installing a wix coolant filter to their vehicle and wondered if that might be a better solution to add inline with the heater core. I suspect this would be cheaper than flushing all the coolant every oil change. Does anyone know if this would be a reasonable idea to try out? I will link what they used.
