Owner reviews for antifreeze

this is the proper coolant, and the best option out there....Ive used Pentosin G11 blue forever....

I bought a 3/8ths 8 inch long copper tube, 4 screw tightening tube clamps and Prestone Antifreeze...I jammed 3 inches of that beast of a tube in one end and 3 inches into the other and put two clamps on each side to hold that baby in. There were flares on each end so I know the thing can't slip out at either end. It was a perfect fit. I then dumped that Prestone Antifreeze into the car and went for a test drive. NO LEAKS!

I've used G12 and Prestone in one of my Corrados. No noticeable difference in performance or running temps. I did 100% complete system flush when changing over. I like the Prestone for availability.

i use the GM red coolant in all my VWs (gas and diesel) without issue.. it IS IMPORTANT to flush the entire cooling system very good before switching from green to red tho.. they do not mix.

You can regualr coolant as long as COMPLETELY flush out the system. I ran Prestone in my Jetta with regular flushes for 3 years with no problems...an no pitting of my cyl. head

i run prestone in my 1.8T and have ran it for 6 months now ever since i put a new radiator in bc my old one cracked so my g12 was completely flushed out. no problems for me.

Coolant I've never had any issues mixing dexcool with any of the stock coolant from Audi or VW.

Installed a new Coolant Temperature Sensor Flushed cooling system Changed thermostat from 87C to 80C Installed new Radiator Fan switch 85-95C Installed new heater control valve as old valve was seeping coolant Replace all hoses

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.

I think you should be fine. If it was the Prestone that you can add to all makes and models, that coolant is compatible with a wide variety of coolants. I have mixed that stuff with Dexcool and green stuff with no issues.
