I checked the directions of WaterWetter (for Diesel) and it said one bottle (15 ounces) per 10-15 gallons cooling system.

My cooling system (603 engine) only has 8 liters (around 2 gallons). Does this mean I jut put 20% of the 15 ounce WaterWetter bottle?

Can't I just pour the whole bottle?


Thanks!

Francis - I've used the entire bottle in an M103 motor. For what it's worth, it had no affect whatsoever on the running temp of the car. That's just my experience. Others have opinions contrary to mine. Regards.

I have a 606 engine, and dumped the whole bottle in when the side resivor was low enough. Can't say i saw any real difference. I understand that certain types of dirt track racers like to use it as they don't use or aren't allowed to use antifreeze, so it's water and Water Wetter to help cool.

I've also heard of people using Water Wetter in water to air or whatever the method is for those types of intercoolers with the same idea in mind, get it cooler, air more dense, more HP. Don't know if that really yields results.
