Question:

I have a question. Is the radiator additive water wetter good for your vehicle?

Does it effect long term performance? I need to know before I put it in.

Answer:

also check your gas tank everybody was making comments about the gas smell coming from my truck turned out to be a leak in my gas tank, whatever you do don,t toss a cig out and get it checked out as soon as possible, you can also postion a small bowl or something under your car to see if the leak is from the tank
If you smell gas when you approach your car look under the hood, and look for fuel everywhere, if you don't see any fuel start the car and look for it spewing, depending on the vehicle the leak could be anywhere but your tailpipe. Look on the ground too!
Water wetter is used by racers to improve the cooling capability of water. If you try to add it to a vehicle which has antifreeze in it it may form a sludgy plug. A mixture of antifreeze and water does not need water wetter.
Water Wetter is sold only by Snake Oil salesmen through the Snake Oil distribution system. Water Wetter is on the same level as a vacume cleaner picking up a bowling ball. Impressive to the uninformed, but as a bowling ball moving devise, totally unnecessary. The idea behind Water Wetter it that it dispelles the surface tension of water. Well, guess what. So does antifreeze. Not that it intended to , but antifreeze is an oil based product and of the many compounds that go into it, one is designed to assist in the mixing of the product. Water Wetter ADDS nothing to the equation as far as the coolant function is concerned. Keep it full, keep it tested for chemical strenght, and keep foreign products OUT of the radiator. IF it is determined that you need an additive to make the cooling system come up to snuff, you are most likely in need of a serious system inspection and service. Have it done RIGHT. A properly designed and maintained cooling system coupled with proper operational limits needs NO additives. This statement does NOT apply to diesel cooling systems.
A 50-50 solution of antifreeze and water should be all you need in a clean properly operating sytem. If the additive was needed the car dealers would carry it and makers would install it. It probably is some type of sulfacant. The same thing can be achieved with the antifreeze. Beleive it or not a few drops of ordinary liquid hand soap will do the same thing. It makes the water wetter by binding molecules together.
