Which Brand of Antifreeze / Does it matter?
 

I'm doing a coolant flush due to totally dismantling the entire intake manifold on my car. I'd like to know if there is a "preferred" or "high quality" brand of coolant that is noticably preferable to any other brand, and also, what do you guys use in your car?

I'm not considering using Evans NPG/+ or any non-traditional coolant yet, since the engine is probably going to be due for a rebuild in the next year or two anyway and I'll switch to a low pressure system then.

So, with that in mind, what is your opinion on the subject? :)

I've no complaints about Prestone's flush.

But the instructions to leave it in the motor for 10 minutes are baloney. Put it in your 7 and then take it out for a half hour cruise. Let it circulate and do its job, then drain it...

Yes, Prestone.

Nice link. :bigthumb:

I use Prestone with some RedLine watter wetter.

I second that (Prestone with water-wetter).
