Who's using the Prestone All Makes/Models "DexClone" or its generic equivalents in their vehicles?

I'm using it in the Saturn right now ('96) and so far, it hasn't shown any problems. I plan to flush/fill once more within the next 6 months though...

Thanks.
 
Same coolant, same car. Just did a dump of the rad this morning, actually. Going to do another one tomorrow if it dosen't rain and call it good for another year or two.
 
I used to use the Prestone "Dexcool approved" with the mostly orange label and orange cap. It's not the all makes all models stuff, this was actually orange. It seems to do it's job, however the 3.4L GM engines that it is in have the bad intake manifold gaskets, one just got its gasket replaced, and the other now has the Prestone LowTox in it and is doing fine.
 
Doing it now, in a 00 saturn, 99 bonneville, 99 intrigue. (The saturn got Supertech, the 99s genuine Prestone I got on clearance.)

All doing great.

The prestone dye is very faint, so old red dye, when not completely purged, "poisons" the prestone appearance. I expect no chemical problems though.

It is bothersome with translucent surge/overflow tanks, as I have to open the top to get a good reading, as opposed to quicker through-the-plastic peeks.
 
So, while the "decision" (not binding arbitration, by the way - more along the lines of an advertisng advisery with no compliance teeth) appeal is pending, Honeywell will continue crying all the way to the bank. If Honeywell "loses" the appeal, , Honeywell will then cry all the way to the bank, instead...

I've had my current fill of it in my engine for about 18 months so far. It'll get changed this fall. There are no signs of any problems, nor were there with the factory Dexcool. I did change over to the "green" stuff during the height of the "Dexcool is the devil" phase and had that turn cloudy within 6 months. That's when I changed back to Dexcool. Everything's been peachy ever since.

We'll see.
 
I put their yellow stuff (generically packaged as Advance Auto Parts brand) in the 1999 Subaru Forester that I just "inherited" from my parents. I did a drain of the factory fill stuff (the car only had 18,000 miles on it when it changed owners) and did 3 consecutive flush & drains with 1 gallon of water per flush; there was very little green tint left; I then added a 50/50 mix of coolant and tap water;

it read a bit weak, so I kept drawing a little of the 50/50 out of the radiator and adding straight coolant once daily for a week and now it reads good (+265/-34); I also added 1 125mL container of the Subaru Cooling System Conditioner (stop leak and head gasket reinforcement agents);

I should be good to go for a lllooonnnggg time
 
You've got me interested in this Subaru Cooling System Conditioner now. I know that GM has its coolant tabs, but since those are solids I've been nervous about using those in my coolant thinking that they wouldn't dissolve properly. Maybe I don't understand the GM coolant tabs because I've never used them. A manufacturer recommended product that isn't a solid sounds very interesting to me, is it completely liquid? Is there any other liquid gasket conditioner/stop leak product that is either sold, made by, or recommended by a manufacturer?
 
Well, it's been nearly 2 months now since I've installed the Prestone coolant, and I have no issues to report. Color/odor was a pale green the last time I checked it, and no serious abnormal odor to report. Then again, I haven't been able to get the surge cap off recently. (May've tightened it too tight)

They're not designed to dissolve completely. They will remain in microscopic pieces supposedly to "scrub" seals and form a physical seal in the event of leaks. When exposed to air, they will help "plug" holes.
 
I can't tell you much about the Subaru Cooling System Conditioner other than it is a Subaru of America approved and recommended problem fix-it/prevention they developed when some 1998 & 1999 Subarus started having major head gasket leaks and then cooresponding TSB'S and recalls being issued.

My parents owned my particular Forester before me and didn't get a recall and did not ever need to have a leak inspected. I started reading alot about it and decided to err on the side of caution and install it when I changed out the coolant since I do not have the money to pay for major repairs out of warranty.
 
I don't ust dexaclones in my car and truck.
I use texico, there the only ones I have found that still make it the old way. Just like what I need for my 1985 Z28 and 1984 6.2L Diesel suburban.
 
What kind of condition was the drained coolant in? (A cloudy and/or discolored appearance would indicate complete exhaustion of the corrosion protection. If the reserve alkalinity was shot, resulting acid buildup will take its toll.) Was there any scale buildup or corrosion present in the radiator? Whatever is found in the radiator will be present elsewhere in the cooling system. The tubing of a heater core is exceptionally thin-walled for maximum heat transfer efficiency, so a heater core is often the first thing to go if cooling system problems arise.
 
My o5 Pathfinder says to use the green any other "color" as they state in the manual, may cause damage.
