Yo guys,
Every few months my Anti Freeze gets clumpy. Which kind do you suggest i use, the orange or greenish. And any brand suggested? I am thinking of getting an Antifreeze flush. Could it be my fuel pump?

lol, my guess is u put in the green without flushing the system. dex-cool and regular(green) coolant are NOT mixable. ive heard regular coolant is also corrosive to our aluminum engine blocks. i'd stick with dex-cool(the orange stuff)

I believe the official Texaco statement was that if you mix the green with the orange, you just shorten the lifespan to that of the green. The orange is just a silicate-free formula. You do want to make sure that you keep it up to the full line or the dye can precipitate out of the antifreeze and that's what causes those greasy formations people complain about (that's what texaco said).

Hmm. I've never heard anything about the green being bad for our cars, I'd always heard it would work just fine...as long as you do a COMPLETE flush...but yeah, the two kinds don't mix well ha ha!

Yeah, what everybody else said. I tried using the green stuff in a Sunfire (they also use Dex-cool), and it overheated before I even pulled out of the gas station. The green and orange do not mix.

alrighty thanks guys

I will get an anti freeze flush and then get the orange stuff :P

Make sure the flush goes thur the postive way. DO NOT DO A BACK FLUSH!
