im gonna be doing my clutch here soon and wanted to go ahead an change the coolant.

i see the manual shows 50/50 antifreeze/water (which i beleive i can just buy at auto zone)

how much approx does the ds use? if i buy one of the gallon containers i assume this will be enough?

also i was considering getting a container of "water wetter" i can just pour that into the water/glycol mix correct?

**EDIT**

anyone know what size the stock coolant lines are? (are they 7/8? )

 

this mag I have here said 1.9 qt. 7/8 sounds about right but not sure.

A little more coolant info:

Coolant does two things. . . freeze protection (the glycol in the coolant) and rust protection - other chemicals. Additionally, I hear the coolant has some lubrication properties that are important to the water pump.

Coolant (the glycol) has WORSE heat transfer than water. That means that water cools your engine better! So, the less glycol (coolant) you run the better cooling you get! In other words, don't re-fill your overflow with straight coolant. You will only get less cooling when that gets drawn into the system.

Now that winter is gone (it's supposed to be 80 here today!) and you don't need the freeze protection cut down the percentage of coolant to 20% and run mostly water.

Something else to ponder. . . do we need any rust inhibitor? The DS has an aluminum cylinder / head. Are there any steel parts exposed to the water? What are the heads of the radiator made of?

I think Water-Wetter breaks down the surface tension of the water allowing for better cooling. Anyone know how this stuff works?
