Hey guys

Just curious here, is it bad if you put to much coolant additive? And how much would be to much?

I use DCA4

I know that the old stuff DCA2, is bad if you put to much of it (can't remember why) but is it bad to much DCA4?


Thanks

 

In theory you can put to much in. What can happen is that you have so much in the coolant that it will have too thick of a coating on a cylinder wall and cause a hotspot. I can't say that I have ever seen that in a motor out of a road tractor. It could be allot easier to happen in a 6.9, for example, because there isn't near the cylinder wall deflection in one of these motors then say a 3406 Cat. One thng you want to do is pour your additive in the rad on it's own. You want to drain some coolant out and mix it in and pour your coolant back in. I drain mine when ever I need to add it and pour the coolant back in.

 

This doesn't make sense!


You do or don't mix it first?

 

He drains some out and mixes it then pours the mix in.
Get the test strips and you will know how much if any to add.
