coolant left in block

[melloelky]

i put a gallon of straight coolant in to go with the remaining water in the block and did the rest 50/50 it tested good to 0 degrees.I'm thinking of draining a gallon out and putting in a gallon of straight coolant in its place.

Are you driving it in winter or just storing it. If its for storage only then its OK. Even a small amount will keep the water from freezing solid and cracking a block. Just be sure that you run the motor and get it mixed real well.

I would put a gallon of straight antifreeze in it. And then 50/50 the rest.

I'm only storing it in the winter but I'd like to have more piece of mind really.I'm gonna pull some 50/50 out and put in the straight coolant.I'm thinking of pulling two gallons out and replacing it with two of the straight and test it.i don't know maybe i should stick with just the one gallon of straight.

Is it going in a detached garage? Mine is attached to the house, so I put a cup of water on the hood. If the cup starts to freeze, then I start to look at it.

A lot of bottles have a guide for ratio vs temperature... I would shoot for whatever would be safe for your record low temperatures.

i did adjust the amount of straight coolant in the system and it did change it to a lower freezing point.thanks for all the help.
