vs
Antifreeze Pentosin or OEM Volkswagen
Reviews
O'reilly around me carries the correct G12. Brand is Pentosin.
Pros: carries correct G12
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.
Cons: seriously low coolant
Vehicle:
Volkswagen Jetta
Mileage: 7000 km
this is the proper coolant, and the best option out there....Ive used Pentosin G11 blue forever....
Pros: best option out there
Vehicle:
Volkswagen
VW G12 and Pentosin G001200 are the same thing, both are pink/violet in color, phostphate, nitrite, and amine free. You should not mix cheapy prestone / o'reilys with the G12, it may turn the coolant to a sludgy substance and clog the system. Basically solidifies when mixed with other coolants. Also may build up rust or other small deposits through your cooling system.
Pros: phostphate, nitrite, and amine free
Cons: coolant turns sludgy, clogs system
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
Pros: coolant quite different
Cons: corrosion in hoses
Vehicle:
Volkswagen
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.
Pros: good for vehicle life
Mileage: 100000 km
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
Pros: no problem
Cons: coolant broke down
Vehicle:
Volkswagen
Mileage: 5000 km
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.
Pros: no problems
Vehicle:
Volkswagen Golf
Regarding genuine VW antifreeze and generic...from what I understand, anitfreeze like Prestone is phosphate free but the real VW antifreeze (Pentosin) also has protectants for the plastic parts of the system, etc. The genuine stuff really isn't that expensive from the dealer.
Pros: protects plastic parts
Cons: phosphate free
Vehicle:
Volkswagen
