coolant again

All anti-freezes you'll see in the store nowadays will be safe. I just use what ever is most affordable. There are two main colors (red, green) however all green you buy today will work with cars shipped with red.

Yeah if you never ever want to ever convert the system back and if you want to be stuck changing the coolant EVERY 2 years or 36k miles... Want some water from the creek to mix with that?

Mmm....... lots of people say that, unless you do a thorough flush, you should not mix colors. If you have green stuff in the radiator already, you should continue to use green stuff, and vise versa. In addition, not all green stuff are phosphate free. Just the other day, I went in a Pep Boys store and looked at the coolant in there. They have their own ProLine brand coolant products. One of them was ethylene glycol based. But it contains phosphate. So definitely not for my saturn, for phosphate will damage my aluminum engine.

The two colors don't mix. You will have pockets of green and orange in your engine. I made the mistake and my water pump started leaking green even though the overflow was orange. Don't mix.

You make no since. They do mix to a nasty blend. They mix to what ever muddy color Orange and Green make. The only reason yours had 2 different colors is because the engine hadnt sucked or expelled any coolant to your overflow bottle.

By the way...OLD THREAD!

They will mix but I wouldn't... it makes a nasty looking color. Anyhow...

Just go to Saturn and buy a gallon of the proper coolant. I do and it costs me around $10 a gallon. Big deal - $10 every other year and you know it is safe. One gallon is all you need on a bi-annual flush and fill. My Saturn parts guy throughs in the 2 conditioner tablets needed after the refill.

I have owned my '92 since new and absolutely no problems. James

I was at Pep Boys and they had a phosphate free Havoline anitfreeze. Printed on the jug it said "May not meet Saturn or GEO factory specs". Stay away, and go to Saturn.
