You should use what ever color is in there. But they do make , what they call a global mix (usually green) that can be mixed with all other colors of anti freeze. 50/50 mix gives you protection down to -20 degrees. If you live in a colder area, use straight antifreeze.

SOURCE: Where is the radiator cap on 2001 Olds Alero?

if you dont see a radiator cap then the cap for your resevoir tank also serves as your radiator cap, thats where you would put your radiator cleaner and dex-cool in at. it is pressurized just like a normally radiator is with a normal radiator cap on it so dont open it when its hot! the resevoir cap should also have dex-cool stamped on it

What kind of antifreeze do I use for my 1999 Saturn


Well, a 50-50 solution of any good green AF is okay, unless you have the dex-cool, orange colored, GM brand type of AF... If you have that, you want to use orange again. You cannot mix dex-cool with regular green AF (like Prestone or any brand AF that is green colored). A lot of people don't like using dex-cool so they change to regular AF. But to do so, you need to flush out every trace of the dex-cool. If they get mixed, problems like sludge in the coolant may result.

Can I replace my dex coolant with regular antifreeze? in my 1997 chevy malibu and how


they say you cant mix different coolants but you can go to auto-zone etc, and buy a cheaper anti-freeze for general motors products. its a 50/50 mix for all gm cars and trucks.you can add this coolant to any brand of anti-freeze. its called universal type anti-freeze. to run a differant anti-freeze in it, you have to flush out complete engine and radiator because the dex-cool and the green stuff do not mix well and cause engine corrosion etc. dex-cool is reccomended for all chevy engines. good-day !

I need to know if I have to use dex-cool antifreeze in my car? Or can I use a universal product?


you can use an all make all models anti freeze, it will mix with the dex-cool but i suggest that you flush the dex-cool out of the system then refill with an all make all model anti freeze.

What type of anti-freeze is recommended?


Many newer cars from GM require Dex-Cool, but if you read the labels of regular antifreeze, from Prestone, for instance, the warranty is still 5 years and it can mix with any color antifreeze.

I use regular antifreeze vs. Dex-Cool in my 1997 Cadillac Deville and, (knock on wood) haven't had any problems.

I believe that Dex Cool is a little bit more expensive than regular antifreeze.

Use a 50/50 mixture of whatever type you plan to use, though.

My truck only overheats when the a/c is on


Start with the simple and replace the thermostat and also replace the coolant. The Dex-cool is only good for 150,00 miles or up to 5 years and any thing longer then that, the coolant crystallizes causing a flow restriction throughout your cooling system.
There is a TSB for thew servicing of coolant that needs to be done before replacing the Dex-cool. The cooling system needs to be flushed out to get the crystal deposit out of the system if there is any.
Gm uses Preston radiator flush to clean out the radiator and heater core of any deposit that will restrict the coolant from flowing throughout the system. Once the system has been flushed out, replace the thermostat and replace the Dex-cool with a 50/50 mix of water and Dex-cool for the best result in cooling. Too much water and the coolant will boil over and too much Dex- cool will jell up causing poor circulation.

Is it ok if i used Prestone 50/50 Prediluted Antifreeze/coolant for my 2001 chevy blazer other than dez cool? I did not mix the two i ve been using the Prestone since i had my blazer for about a year.


It's OK to use Prestone 50/50 Prediluted Antifreeze/coolant. But, it needs to be DEX COOL. There is a reason for it. The seals and the water pump in the cooling system are made to run with the DEX COOL. Anything like a non-compatible coolant will cause problems down the road. I wouldn't risk it. They do make 50/50 DEX COOL.
