Going to be replacing my radiator and water pump soon, so draining the radiator will of couse be done. Should I reuse the old antifreeze or just start over again using fresh batch of distilled water, water wetter, and antifreeze?

You don't reuse toilet paper, do you?

Well it depend's if it's old fluid like more than 2 month's old don't reuse it.

If you just installed it say a month or 2 ago i would reuse it but pour it thru a paint strainer to remove any debris.

I have done this in the past but the fluid was only 2 weeks old and i have not had any problem's from doing this.

And i know im not the only one in here that's done this so anyone that's gonna give me any gerif just SHUT - UP ! :p

I would never reuse antifreeze the stuff is cheap its better to be safe knowing you put fresh in.

my chiltons book states it's all good under 2 years. i'd strain it though. it's nasty stuff to toss into the environment, might as well use it for all it's worth.
