WHICH COOLANT DO I USE ??????

What coolant do I use in my 03 Deville 4.6 Northstar?

The boss can't find the owners manual and it has GREEN colored coolant/antifreeze

in the res. bottle so I am stumped...........................

And of course no rad. cap to eyeball whats in there !

My 04 truck has the pink Dexcool and I thought all GMs after 96? use the pink Dexcool.

I doubt its ever been added to or changed because I have had it from new.

Any ideas?........TIA........geo

There is a pressure cap on the reservoir. If the level in the reservoir is such that you can't see the color, roll up a piece of paper towel and dip it in there. And then hope it is not green.

Sorry, but I did not read your post accurately the first time.

If you are seeing green in the reservoir, then that is what is in the radiator and the entire system. Someone, somewhere, sometime has added something to turn it green, It was factory filled with Dex-Cool.

Have you ever taken it to a quick change oil place where they topped off all your fluids?

Well guess what!

Never underestimate the amount of a persons greed.

That is correct -- all GM's after 1996 use Dexcool. Yours has had green coolant added to it.

I know there is that universal stuff which is yellow (forgot the name).

Its just the unknown because I can't tell what is actually in the system

because their is no rad cap I can't look see . I know better than to mix the different kinds. Of course there has been FEET of snow in

my area of NY so have been driving the truck and plow.

The rest of my rides are on the winter sleep....................

Don't know if the cold weather has effected the DIC because I

have been getting a low tire pressure warnings (all good) along

with a low coolant msg. (res. full to marks).............

Haven't driven it too much lately!

The odd colored coolant has me wondering..............

Air pressure will decrease as temps decrease and increase with temperature. I think the rate is about 1 psi per 10 degrees. Coolant is another story. You may have a problem there.

If you add coolant, add 50-50 DexCool and distilled water. WalMart and others carry distilled water for about 50 cents a gallon.

I usually keep pre-mixed coolant on hand. You can either buy it premixed, or you can mix it yourself. Just get a gallon of coolant and a gallon of distilled water and fix yourself two gallons of 50/50. And then label it so you know what it is! It may sound like overkill to have that coolant on hand, but sure enough, when you don't keep it, that's when you'll need it.

Thanks all...............I suppose as long as the weather breaks

I will take off the upper hose and check the color of the

antifreeze thats in there....................

If its green ............Hmmmmm

If its pink/orange I will just drain the overflow/res. tank and refill

with Deathcool.............

Always had oil changed at the Caddy dealer or the little mechanic shop up the street. Them guys are sharp so I doubt they filled it with the

wrong stuff............The Caddy dealer????????? They charge for

EVERY extra (washer fluid, ps or trans. fluid etc.) and if they put in

any antifreeze they would have noted it as well as charged for it!

Can't kick because except for a oil change or 5 and a emission recall

(PCM reflash) I haven't seen the dealer much at all except to drool

over a XLR or a CTS V. But they have been great and will gladly

hand over the keys IF they have a demo hanging out !!!!!!!!!!

Not expecting to trade this Caddy soon. Only 45k miles and I like

to run them to 100k plus miles !............geo
