Dexcool is also an ethylene glycol product but is red. Been using that for a while in case anyone wonders lain specs all of its pumps to run glycol mixes.

I know, I have a GM car, I was just stating the traditional colors. Ethylene Glycol is traditionally green and Propylene glycol is traditionally pink.

Are the traditional colors even still sold anymore? I've done lots of vehicle maintenance recently and all I see at wallyworld nowadays are the yellow universal coolant and the usual orange Dexcool.

Very few places cary traditional green anymore most people are using universal yellow which is still ethylene glycol as well, but carries some of the same additives Dexcool would carry.

Are the traditional colors even still sold anymore? I've done lots of vehicle maintenance recently and all I see at wallyworld nowadays are the yellow universal coolant and the usual orange Dexcool.

Yes at parts stores they do.

Don't mix both it makes sludge that do shit to your cooling system with time. Trust me i'm a car engineer! In other words...i'm a really good mechanic who make miracles with people shitty cars :p

No adding the yellow to a red or green system will do nothing the issue comes with adding green to red or red to green. Dexcool and normal coolant turn solid over time and will mess a car up.

yellow is still Ethylene glycol based red/pink/orange is dexcool dexcool isn't bad on its own but if you go mixing shit with it expect to be changing a water pump and or headgasket in under 20k

Dexcool is still ethylene glycool. Pink is propylene glycol ie non toxic. The additives of Dexcool are what cause gelling and solidification when mixed with normal green goop not to mention some of the older cars the additives will eat the seals.

The additives of Dexcool are what cause gelling and solidification when mixed with normal green goop not to mention some of the older cars the additives will eat the seals.

That's what I read on wiki, but it's sketchy:

Organic acid technologyCertain cars are built with organic acid technology (OAT) antifreeze (e.g., DEX-COOL[18]), or with a hybrid organic acid technology (HOAT) formulation (e.g., Zerex G-05[19]), both of which are claimed to have an extended service life of five years or 240,000 km (150,000 mi).

DEX-COOL specifically has caused controversy. Litigation has linked it with intake manifold gasket failures in General Motors' (GM's) 3.1L and 3.4L engines, and with other failures in 3.8L and 4.3L engines. One of the anti-corrosion components presented as Sodium or Potassium_2-ethylhexanoate and Ethylhexanoic_acid is incompatible with Nylon_6,6 and Silicone_rubber, and is known as Plasticizer. Class action lawsuits were registered in several states, and in Canada, to address some of these claims. The first of these to reach a decision was in Missouri where a settlement was announced early in December 2007.[20] Late in March 2008, GM agreed to compensate complainants in the remaining 49 states.[21] GM (Motors Liquidation Company) filed for bankruptcy in 2009, which tied up the outstanding claims until a court determines who gets paid.[22]

According to the DEX-COOL manufacturer, "mixing a 'green' [non-OAT] coolant with DEX-COOL reduces the batch's change interval to 2 years or 30,000 miles, but will otherwise cause no damage to the engine."[23] DEX-COOL antifreeze uses two inhibitors: sebacate and 2-EHA (2-ethylhexanoic acid), the latter which works well with the hard water found in the US, but is a plasticizer which can cause gaskets to leak.[16]

According to internal GM documents,[citation needed] the ultimate culprit appears to be operating vehicles for long periods of time with low coolant levels. The low coolant is caused by pressure caps that fail in the open position. (The new caps and recovery bottles were introduced at the same time as DEX-COOL). This exposes hot engine components to air and vapors, causing corrosion and contamination of the coolant with iron oxide particles, which in turn can aggravate the pressure cap problem as contamination holds the caps open permanently.[24]

Honda and Toyota's new extended life coolant use OAT with sebacate but without the 2-EHA. Some added phosphates provide protection while the OAT builds up.[16] Honda specifically excludes 2-EHA from their formulas.

... update on OP: Loop seems to be getting better with second flush, vortex in the resevoir is a lot more pronounced, some floaties circulating from the scrubbing I did (I think). I think I'll flush it one or two more times before popping the motherboard in.

This is what i've meant. The mix of green and pink will give shit. The yellow one i never seen it around here even if I make car mechanic for 18 years now.
