Hey all,

I flushed my cooling system, I mean COMPLETELY. lol It is pretty much pure water in there now. I drained the radiator last night and refilled it with 100% coolant. Do you think the mixture will be 50/50 once it starts to circulate?

The block was pretty much all water. The radiator is now 100% coolant. 50/50 mix now?

On my way to work, I had to make a few stops on the way. I let the car idle. It should've had a chance to mix mostly by now.

Anyway, do you think I shoudl drain the radiator one more time and add a true 50/50 mix to it and call it a day?

 

not meaning to jack your post but.... what are the advantages of 50/50

i always did strait coolent

 

I think straight antifreeze actually boils and freezes before water does (smaller termperature range) or so I've heard. It's the mixture of the two that allows for increased boiling and freezing capacity.


AndyD - I would think as long as you think it is close you would be ok. If you checked your cooland with one of those measurers (the onese with the floating *****) I would think it would tell you if you are close.

Exactly. The point of antifreeze is to change the boiling/freezing point of water. It's not an agent used as a substitute for water.

Yeah, I think I should be close. I was just wondering if the capacity in the block is almost the same as the capacity in the radiator.

I filled the radiator and the coolant reservoir tank with straight coolant.

I just wanted ot make sure.

 

I would think your mix is near enough to be a 50/50 but the sure way is to get a hydrometer to test the strength precisely, the other advantage besides stopping freezing up in cold climates, is that antifreeze acts as a corrosion inhibitor which helps stop further sluge build up in the future, so cutting down on the need to flush as frequently.
