Is it time for a coolant flush?

Hello. I noticed my coolant to be a little low. Its just below the cold fill line. I haven't seen a recent post about coolant on here so im asking if i should just add some Dex-Cool to it? Or do i need to do a flush? its been at least 2 years since i haven't touched it. Thanks again

According to the manual, it's every 5 years or 150,000 miles; whichever comes first.

The car is 8 years old. i got it 2 years ago used. Im assuming the previous dealer didnt do it but im not sure. So i think it would be best to do a flush

The 50/50 is already diluted with water. The regular Dexcool is full strength and need to be mixed with water. I've always thought that the 50/50 was a rip-off.....

You late model GTO guys still run that Dex Cool? In the "GTP World" that **** is always flushed out and replaced with conventional "green" antifreeze. Dex Cool causes all kinds of problems with clogging the cooling system and tearing up seals on the intake manifold. Just curious.

Depends on the price of the 50/50 compared to 100. You do not want to use tap water to cut Anti Freeze.

Unless the price of the 50/50 is at leat half the cost of the 100%, which it never is, the 100% is a better buy. Unless the water where you are is crap, it really doesn't matter. I've mixed tap water with antifreeze all of my life (and that's a long time!!) and I've never had it cause me any cooling system related problems.

Not true.
Clogging: Many think the sludge in the overfill is a breakdown of DEXCOOL when in fact its a rust inhibitor placed in there at factory to prevent corrosion, and to keep the internal workings of the water pump etc lubricated.

Many panic and say OMG the coolant has broken down. They flush this additive all out and replace with conventional anti-freeze. After a while things start happening to their radiator and other parts associated with cooling. Many come in here seeking answers to why did my radiator blow? Why did this happen? You ask them did you replace the DEXCOOL? The common denominator to most answers are: YES my radiator had sludge in it from the DEXCOOL and I replaced with conventional Anti-Freeze.

The owners manual clearly states use ONLY DEXCOOL. My 2004 Grand-AM says use only DEXCOOL.... My 2007 Doge RAM says use only: MOPARS version of DEXCOOL.

Little ironic its the GTOS using this new formatted coolant that has all these issues isn't it?

Many are ignorant of the proper additives for this car, from DEXCOOL to synthetic oils to F.M. in the rear end.

The only issues I see are from those who are not properly maintaining these cars. MOSTLY 2-4th owners of the car.

Tearing up seals? These motors are designed to be using DEXCOOL. Maybe the seals some are reporting being torn up is being done so by improper coolants or other factors.

Many know it alls on these cars who post their authorivite knowledge on them turn out to be shall I say less than astute on them.

USE DEXCOOL ONLY.... on this new GTO....

My '70 or older cars? NO!

Whenever in doubt ...... read the friggin manual.
