Which it being summer and my jeep running a bit on the hot side, I thought I'd try some water wetter. I was running 50/50 universal house brand from O'reilly's.
Before I added it, I drained some coolant mix out the radiator to make room. Not much. I noticed a lack of distinct green color. It was slight and oily, but more ear than the mix green color.
I opened the rad cap and the coolant had the green color I was expecting. So I poured in the full bottle of water wetter. The coolant started to flow once the thermostat opened and the pink color of water wetter went away and now the mix is opaque. A "Tom Collins" color without the garnish. (Odd description, all I can think of this morning).
I drone about 20 miles got the engine up to operating temp. Really did not notice a change in temperature.
This morning I was curious as to what color the coolant might be. I googled and found all kinds of stuff about a sludge and brown color. When I opened the cap, I found this
There are pink floating globs, small, but there. The color is now more green and clear.
Is this something to be concerned about and should I flush the system?
Here is what I have done so far in the system.
-New radiator, ran a while still had cooling issues.
-new rad cap, water pump, thermostat (does not have small air pass through hole like OEM) and heater core (leaking so I went ahead and changed it). The previous owner had used stop
Leak in system for the heater core leak as when I flushed the system for rad change, it came out light brown and had brown residue on the rad cap and on thermostat. I have not replaced hoses.
Should I flush and start over with a better fluid? Side note just after I added water wetter, I noticed some general floaters going by like a very small hair like amount of blue RTV and some flake like stuff I attributed to the residue of stop leak in hoses.
I am just wondering if I screwed up putting in the additive or am I fine?
