Antifreeze OEM Volkswagen or OEM Toyota

The green does "work" but it wont help the health of the engine long term as there are chemicals in the Toyota red which help protect the engine, fittings, rad etc. Buy the right stuff from Toyota and it'll last ages, the wrong stuff will screw things up long term.

I did this a few weeks ago on my '13 Sequoia, but I did not flush it. Just drained the rad and the valves on the block. Replaced with Toyota red and distilled water at 50/50. The fluid I drained was as clear as the fluid I replaced, so I felt flushing was not necessary.

Toyota brand coolant is top notch, supposedly can last for the entire life of a car and never needs to be replaced

I got the light this morning on the wife's JSW. So I checked out the situation. Sure enough seriously low coolant, like well below minimum fill line. Only 7000 miles. Took it to the dealership to have it topped off.

for vw's; i prefer using the 50/50 coolant from the dealer my gf's 2.0 had a small leak for months and we just kept on topping it off with the pepboys stuff-- but once i replaced the thermostat housing you can see corrosion in the hoses and the old housing -the coolant from vw is quite different than aftermarket brands (you can really tell just from its thickness-- i suggest forking the dough over for the vw stuff -other cars; i don't know

G12 may cost 12 bucks a gallon, but you only need one gallon and the manual states it is good for the life of your vehicle.

i run the G12 - every vw i ran G11 in, the coolant broke down after 5k miles, but the minute i swiched to g12, i have yet to have a problem

The mk3 came with G11 coolant. The mk4 came with G12 coolant. I'm running G12 in a well-flushed mk3 radiator, and I have no problems.

I'm flushing our 14 Tiguan this weekend cause the coolant is nasty as hell.

I also had the coolant replaced. I asked for the OEM stuff, which I guess is pink (?). They said mine was pretty much black !
