Re: [MBZ] Prevent cracks on 603 heads, my solution
Water does not come into 100% contact with your head or radiator because of surface tension and Water Wetter works by reducing the suface tension of the water in your cooling system. The result is better thermal transfer from your head to the water in your cooling system and better thermal transfer between the water in your cooling system and your radiator cooling fins. If you'll look at the chart on the side of their can, you'll note that the product only helps a small amount. You can do the same thing by adding a teaspoon of detergent to your cooling system.

Re: [MBZ] Prevent cracks on 603 heads, my solution
Yes - Photoflo is very similar to water wetter - it's a non-foaming detergent. It also lowered the surface tension enough to let the surface water drain of the film instead of drying on it. It would make a mess of the film if it was not diluted properly, or used past it's life expectancy. I don't know about the temperature issue, so would use the water wetter rather than the photoflo, though doubt a teaspoon would do any harm, it might do any good though.

I have aluminum pots, and I've found that while Cascade is okay, some other dishwasher detergents will pit them. I'd particularly avoid anything with a citrus odor, since it'll probably contain citric acid.

[MBZ] Prevent cracks on 603 heads, my solution
Use Evans Waterless Antifreeze (NPG+) in your cooling system. I have it in three of my MBs and getting ready to put it in number four. It has been in my first 300 SDL for almost four years. I have no way to prove or disprove claims made by the sellers but I do know it won't boil until it reaches over 300 degrees F, they claim 375. I know there was very little or no pressure released when removing the coolant cap after some hard interstate runs and I believe what they claim. I have communicated with one other user on the ShopForum site who believe as I do. He has used it longer than me with a broader application. When we first emailed, he had a tractor mower that would clog up, get hot and boil the coolant out, after installing NPG+, no more problem. Before I put it in my 240D, I will try to get some before (and later some after) pictures of areas that will be easy to get to later. Evans claims it cleans things. I would like to see if I can tell. Not sure how to go about this yet. Anyways, I'll continue to use it, after all I have to take the word of other antifreeze makers if I use their stuff and both claim extensive testing.

He remembered doing the job, but not how exactly the head was cracked---said he does too many to keep them all straight. Regarding welding the head with high-temp-safe aluminum welding rod... he said they'd tried to do that a few times with heads that only had one or two small cracks, but gave up when the welds always failed quickly and continued to leak. In his opinion the changes Mercedes made from one redesigned casting to the next were not enough to change the basic fact that aluminum is not as resistant to the stress of expansion and contraction from repeated temperature cycles as the iron head on the 617.

You will also notice a slight improvement if you add a small amount of detergent to your water. The detergent drops the water's surface tension improves heat transfer between the head water and water radiator.
