RE: [DML] coolant question

The car will run hotter because antifreeze is not as
efficient at removing heat from the engine and giving
it up at the radiator. You really should drain the
system and refill it with the proper mixture.

For maximum heat transfer, you should use straight
water with some water wetter. Water wetter reduces
the surface tension of the water, which improves
it's heat transfer characteristics. Do not add water
wetter to an antifreeze mix. It won't help and may
reduce the effectiveness of the antifreeze in cold
temperatures.

Subject: [DML] coolant question


Hello, Can someone please clarify this for me?

Will running straight antifreeze through your car cause it to get
hotter?
Last week I had a coolant leak and lost nearly all of it. I didn't have
any
water so I fixed the leak and put in straight antifreeze.(almost 2 gallons
if
I remember correctly) I have left it this way because a friend said it
doesn't matter at all, mixing it just saves money. Is this right?
