It is possible that even though a flush was completed, the heat of driving it softened and released more of the crud that is in the entire cooling system, now giving the coolant the contaminated look.I know Jason and I guarantee he did a proper flush including the rear heat. He is very meticulous about his work and procedures. You are going down a rabbit hole with this one pic diagnosis. If truck is running at correct temp then id keep going and have him check it at your next appointment.
Where are you buying this? I've been paying over $45/gallon for it because I cannot get them to ship it. Molle Toyota and Olathe Toyota are within a few dollars of each other on it.Cost on red is also not a big difference. With discounted toyota parts prices I can get a gallon of Red for $20 and change. Thats not a mix so when you go 50/50 it puts it at $10 a gallon. It is a bit harder to get on the trail.
Thank you!29.60 is list and multiple places give 30% discount.

I'd add to this that it's only effective monitoring if he has a gauge installed (or wifi dongle for phone). Otherwise the temp needle won't move unless it's starting to overheat. If you hit that point, clearly there's a problem... but it could be running warmer than it should due to gunked passages, though not overheating, and the 80's gauge will still be in the middle.Pay close attention to the engine temperature while driving. If it’s normal- that’s great. If it seems to run hot more than you remember — this might be the reason.
