What is the correct type of coolant for a 300tdi?

Is there a specific coolant type recommended for a 300tdi engine? I have had a mechanic in the past say my coolant had the "wrong" color (that I had the wrong coolant) for this engine. Can the wrong type of coolant be harmful to the radiator or block? I just bought this Zerex G-05 Coolant to use after I flush the radiator because it said it was for diesel engine and it is supposed to be a mix of conventional and organic acid-based chemistry. Would this be ok to use?

Here's what someone posted on another forum:
Quote:
The standard is an ethylene glycol based (blue) antifreeze with a two year life- at 18.00 for 5litres. The advanced is an OAT antifreeze with a 5 year life at 21 for 5 litres or ready mixed at 18/5l. OAT ( organic acid technology) is for newer aluminium blocks and the two MUST NOT be mixed - it can turn to gel. Look fir the words glycol or OAT in your handbook.
Here's what the 300tdi Workshop Manual says:
Quote:
Use an ethylene glycol based anti-freeze (containing no methanol) with non-phosphate corrosion inhibitors suitable for use in aluminium engines to ensure the protection of the cooling system against frost and corrosion in all seasons.

Personally I prefer to use the normal life antifreeze.

For the past number of years I've been using Peak, but brand doesn't really matter IMO. I get the 100% and cut it 50/50 with distilled water.

Honesty I think any green diluted to 50/50 would be sufficient, that's what I did when I flushed mine and did the p-gasket.

Why green?

Just similar to what Tom suggested, the basic green is sufficient...not sure that the orange would be an issue, but is probably unnecessary.

Hey Manimal, MacGyv here.... I use Prestone. I buy the full strength & cut it to 50% with distilled water from WalMart. Why pay someone to cut it to 50% for you? It's green/yellow, in color. Since hoses are somewhat permeable, you'll always have some lose of fluid, ever-be-it so slowly. I top off the level with the 50% solution.

Thanks McGyver!

I found more info than I ever wanted to know here: http://donsnotes.com/home_garden/auto/antifreeze.html

I got Zerex G-05 because they had very few options at the auto store I was at and it said it was diesel/aluminium engine compatible. It's yellow but after reading the above link it seems the color is irrelevant. Looks like the G-05 should be fine.

Last question. Why distilled water? I was told tap water is fine.

Tap water has impurities (dissolved minerals), distilled water is derived from condensed steam. Steam carries no solids when it goes from the water state to a gaseous state. Water has 3 forms solid, liquid, gas.

Ice doesn't have to go through the liquid state to become a gas.
You may have seen ice go directly to a gas before on your windshield, that process in called sublimation (much like those white stink blocks in a urinal that dissolve but are never wet [mothballs]).

A steam burn is much worse that a boiling water burn. The energy required to go from boiling to a gas (steam) is HUGE. Check this out. To turn 1 gram of ice, 0 degrees Celsius to boil is 100 calories (1 cal = 1gram raised 1 degree C.) To go from 100 degrees C water to steam, requires an additional 540 calories.

http://www.electronicsteacher.com/su...into-steam.php

Actually, steam is an invisible gas, what people usually refer to as "steam" is really condensation, steam returning to the visible state of water at close the boiling point, but below it.

When you put the water or anti-freeze under more pressure (hence a radiator cap) these energy points (boiling etc.) go up. That's why a good radiator cap (pressurized system) is important and always put a rag over a radiator cap when you loosen it when at operating temperatures.
