It can still be had I use it in a 2000 explorer. I did some looking since I read your post, there is a lot out there on the subject.

There are threaded plugs in both heads. It is common for them to be loose causing a slight leak. They can be tightened with a 3/8" extension. turn wheel on vehicle to get access from the ground.

I use Dexcool and have no coolant usage. There was an issue with Dexcool many years ago found to be faulty radiator caps. I have inspected inside my cooling systems on other Dexcool equipped cars with a boroscope and found them to be immaculate.

As for your leak, looks for signs of dripping or coolant running down the lower radiator hose (it may appear as a white streak if dried), that is a tell tale the water pump is seeping coolant. It may take a while for it to get worse but the pump would be my first suspicion. Ask me how I know.

The pump was one of the first places I looked and I was glad when I didnít see anything there. Iíll check those plugs in the head. Oh I forgot to mention because itís been awhile but I did a pressure check on the system and it took about 10+minutes if I remember correctly for it to drop 1 psi. I Donít remember now if it was on a warm system or cold? Whichever was the suggested way to perform the check was the way I did it. I can look all around and smell with a hot motor and canít find anything. Iíll keep looking though because occasionally I get a whiff of hot coolant.

This has been like this since I bought it with 21,000 mi on it. I noticed the reservoir was very low when I looked at it and brought it up on my inspection but told them I would top it off myself if I bought it. I wanted to be sure to put the correct coolant in it.

Google antifreeze colors and mixing.

Not anymore the Prestone coolant (green) has been reformulated to last 5 years or 150,000 miles. It's generally called for in 96 and older GMC engines.

Dexcool takes a bad rap because most times when coolant is changed they don't DRAIN THE BLOCK. There is at least a gallon or more in the block and over time that old coolant thickens and contaminates the whole system. I drain the block and have used Dexcool since new, and change every two years, and that includes the block. Jim, Aerbus, 2003, Rexhall since 2004. can't get on with old ID??

Coolant usage?

I think I was told or read somewhere that Dex-Cool changed their formula through the years?

Got rid of the DexCool many years ago. Not a big fan.

Also had a small radiator fluid leak. Could smell it but couldn't see it. Then I noticed a small cold leak running down the passenger side exhaust manifold.

Fluid was coming from the coolant temp sender. Replaced it and have had no problem since. Used GM part#12572027. A sage mechanic said to replace verses reseal old sender. Part comes with sealant applied.

You might want to check the bypass hose. I had a coolant smell and could never see a leak. I found the clamp slightly loose.

I will certainly look at that to see if thatís where itís leaking from along with the other plugs on the heads. But whatís the big hate on dex-cool anyway?
