In a 94 its safest to use the older glycol base green colored coolant. GM started using the newer Dexcool pink/orange coolant in 1996.
Never mix different type/ color coolants. Always add the same type/ color.

I've used both with no issues. I think the biggest thing is to use distilled water in it

Don't use coolant based only on it's color.
You need to check the anti-freeze if it's silica free. Silica damages o-rings & rubber alike.

OAT coolants can also damage gaskets and seals on older engines not designed for it.

You will need to use GM part number: 3634621 after putting in new antifreeze. This is the coolant system seal tabs. You will put all six tabs in your radiator. This helps to seal the head gaskets and any minor leaks. Many mechanics do not know about these seal tabs.
I have seen many heads taken off when all the car needed was seal tabs. The Cadillac Northstar was probably the worst. |
