SOURCE: Re: Dex-Cool in 1999 Lumina

The major reason for using dex-cool is that antifreeze is often neglected as a service item. If neglected, it becomes acidic over time which is particularly important with the use of aluminium in most major components which are served by antifreeze. Acid causes etching and premature failure of gaskets and permanent damage to blocks, heads and especially the radiator and heater core, which are not vert thick to begin with.
Since "normal" antifreeze acidifies faster than does dex-cool, mixing both together causes a change in breakdown rate...the more "normal" coolant added, the faster it breaks down.
Both coolants do not react chemically with each other and therefore retain the same ability to prevent boil over and freezing.
In reality, normal coolant can be used with little or no effect on components, provided that you change it every year. (that's where the EPA gets involved) They do not want people dumping this stuff into the ground, so they push for extended service intervals. Since dex cool has a longer service life, that's what they want you to use.
As far as how you chasnge the coolant, it is always a good idea to flush system during a change, regardless of antifreeze type. This removes solid particles which can plug radiator core. Radiators are much smaller than their older counterparts. Loss of even a small portion of cooling area can cause overheating. Engine running temps are also higher than older vehicles (heat=power output). Therefore most systems have a much smaller margin of error than before. What I find though is that regular flushing can also be bad for the system as the chems eat away at metal components in order to clean. I recommend regualr or dex cool antifreeze systems be flushed with water only, once a year, but retaining what you removed and filtering it through a coffee filter, using it during the year to "top off" the system. To retain effectiveness of coolant, use a hydrometer to check concentration, adding new coolant to bring reading to proper protection level.Then, every three years, do a complete chem flush and change entire batch. This keeps your system clean and the epa happy!

You can use either one, just don't mix them.

SOURCE: How often should you change coolant in 2001 Chevy

Sounds like air in system, repair any leaks flush and add universal antifreeze, and to get air out without special equipment, fill best as possible, start engine drive around block. Let vehicle set until cold. Then check coolant level again, repeat until guage stays normal

The premix is just for convenience - you can use straight as long as you mix 50/50 yourself.

Diagram for cooling system bleeder valve 02 deville


There isn't one !
Filling Procedure
Notice: Do not add cold water to the cooling system with the engine at or above operating temperature. Adding cold water causes rapid cooling, resulting in possible engine damage.
NOTICE: When adding coolant, it is important that you use GM Goodwrench DEX-COOL® or HAVOLINE® DEX-COOL® coolant. If Coolant other than DEX-COOL® or HAVOLINE® DEX-COOL® is added to the system the engine coolant will require change sooner; at 50 000 km (30,000 mi) or 24 months.
Notice: Do not use a solution stronger than 70 percent antifreeze. Pure antifreeze can freeze at -22°C (-8°F).
Important: This engine is not equipped with block drains, 2.5 L (2 qt) of residual coolant remains in the engine block.
Refill the cooling system. In order to ensure sufficient engine cooling, freezing and corrosion protection, maintain the protection level at -37°C (-34°F) or lower.
Start the engine.
Place the heater and A/C control in any A/C mode except Max and the temperature in the highest setting.
Allow the engine to continue idling until the lower radiator to water pump hose is hot.
Turn OFF the engine.
Allow the engine to cool to outside temperature. Ensure the coolant level in the surge tank is at the proper level (1).

How do you bleed the air from the cooling system of a 1999 v6 pontiac grand am


Refilling Procedure




Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL?"¢ coolant. If coolant other than DEX-COOL?"¢ is added to the system, the engine coolant will require change sooner: at 50 000 km (30,000 miles) or 24 months.






  1. Close the radiator drain cock.


  2. If previously removed, install the engine block drain plugs.


  3. When installing the drain plugs, use pipe sealer GM P/N 12346004.




    Important: On vehicles equipped with the 3.4L engine, open the coolant air bleed valve. The coolant air bleed valve is located on the top of the thermostat bypass pipe/heater pipe assembly. Close the valve once a continuous stream of coolant is expelled from the valve.



  4. Fill the surge tank to the base of the filler neck.


  5. Start the engine with the pressure cap off. Run the engine until the upper radiator hose starts to get hot.


  6. If the coolant level in the surge tank is low, add the proper mix of coolant until the level reaches the full cold line.



  7. Important: After servicing the cooling system, and if the vehicle is equipped with an intermittent low coolant light, an occasional low coolant light may be encountered during some extreme driving maneuvers. This complaint should be eliminated by removing the surge tank cap and adding coolant to a level just at or above the full cold line when the system is cold.



  8. Install the cap onto the tank with hand tight pressure.



Recycling Procedure




Important: Dispose of used coolant in a proper fashion, such as in a used coolant holding tank. Never pour used coolant down the drain. Ethylene glycol antifreeze is a very toxic chemical. Disposing of ethylene glycol antifreeze into the sewer system is both illegal and ecologically unsound.



There is currently no approved method for recycling used DEX-COOL?"¢ coolant into new DEX-COOL?"¢ coolant. DEX-COOL?"¢ coolant can be recycled into new conventional coolant. Consult local listings for coolant recycling facilities in your area.

Hi. 2005 Impala 3.4. My water pump is failing for the second time in two years. Coolant flushed after first pump installed. Coolant flushed again six months ago. Pump is failing again. Thermostat...


WATER PUMP FAILURE COULD BE CAUSED BY WRONG COOLANT USE DEX COOL ANTI FREEZE.REPLACE THERMOSTAT AND BOTH RADIATOR HOSES TOP HOSE AND BOTTOM HOSE.SOFT HOSES COLAPSE LIKE PUMP HOSE.IT WILL COLAPSE FROM PUMP VACUUM CLOSING OFF SOME COOLANT FLOW.MAKE THE HEATER CORE NOT STOPPED UP IF SO IT WILL RESTRICT WATER PUMP BYPASS CAUSE EARLY PUMP FAILURE.YOU NEED 50/50 COOLANT MIXTURE YOU HALF WATER AND HALF DEX COOL DONT USE GREEN ANTI FREEZE USE ORANGE DEX COOL.I HAVE 3.4L ENGINE AND 3.1L ENGINE BEEN USING DEX COOL ANTI FREEZE SINCE I HAD BOTH VECHICLES. HAD NO WATER PUMP PROBLEMS.

Can you use dex-cool in a 2006 scion xb


dex- cool is the orange coolant, you can use this only if it already has dex -cool, dont mix it with the green type coolant, if it has green coolant you will need to drain it before using dex-cool

Which coolant does a 2003 envoy need?


The cooling system in your vehicle is filled with DEX-COOL engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL extended life coolant.

A 50/50 mixture of clean, drinkable water (if the water in your area is of poor quality, it is recommended you use distilled or de-ionized water) and DEX-COOL coolant will:
  • Give freezing protection down to -34°F (-37°C).
  • Give boiling protection up to 265°F (129°C).
  • Protect against rust and corrosion.
  • Help keep the proper engine temperature.
  • Let the warning lights and gauges work as they should.
Hope this information helps

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.
Thank you for using fixya and good luck
