Antifreeze VALVOLINE or OEM Volkswagen

There's Zerex (Valvoline) Asian car coolant (prediluted) that's made in 2 colors, blue and red, and it's supposed to be compatible

Call Valvoline (Zerex), which makes both green and Asian coolants. Most likely the green you bought is not like the green sold 20 years ago.

From the manual: "The manufacturer recommends using MOPAR Antifreeze/Coolant 5 Year/100,000 Mile Formula HOAT (Hybrid Organic Additive Technology) or equivalent." Remember that the Routans are really Chryslers in disguise, so no need to go exotic brands on fluids. So you can try this: Valvoline Zerex ZXGO51 G-05 Antifreeze.

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.
