Would like to know if other 'G' owners found it to help the engine
run cooler during heat stress driving conditions?
In snowmobile racing we used it with good success.
There was a college kid around the shop with a pontiac sunfire that was continuously running on the hot side. Dumped a bottle of that stuff in and we were amazed how well it worked. I saw it with my own eyes. We purposely ran the card as hard as we could and it would not get to the same temperature as it was before just running normal. I am a believer.
Speaking to an engineer from GM he said that the stuff will work and is effective, but really only on a new car with new internal parts. As soon as the radiator and engine block, etc has been run and gets a little crud inside what ever chemical that is in that magic potion won't work nearly as well. In the snowmobiles we had all new parts and did see good success. In the old Pontiac, we also saw very good success contrary to what the GM guy said. SO! Those are my experiences. I think it would be worth the $12 and won't hurt anything. It does NOT change the color of green antifreeze
