Antifreeze issue
My car has enough Antifreeze (green one) in the radiator but little above
the min. mark in the tank. I read Elle's post and thought to top it up and contacted Honda dealer to get the Antifreeze. They said they no longer sale the green one anymore. They sell the blue one. I asked whether I need to flush out the old one to put in a blue one, the guy said "sure!" but after a quasi long pause!! So, my question to this trusted group of mine is: 1) Is it okay to use a generic green antifreeze from Pennzoil? (It's about half the price!) 2) Is it okay to mix it with the old green antifreeze? Does it have any break down period like the way engine oil does? 3) Can I use the double distilled, deionozed water that is available in laboratories? Thanks SB |

Quick response from a 1991 Civic (171k miles) (original) owner:
What I've seen generally is mixing different anti-freezes, even if they're the same color, is a bad idea. Definitely do not mix a conventional Prestone green with the OEM coolant, which may be the blue stuff at the dealer's. Definitely do not mix orange with green, etc. (Of course the color coding implies a particular, certain chemistry, hence the advice not to mix.) Ideally, do a flush (which is just a drain, fill, drain, etc. a few times). You can probably get away with just a full drain (including engine block drain plug removed), but it doesn't take but a few minutes to go the next step and fill and drain a few more times. I just used hose water for this. Of note is that, when I measured all the coolant in my Civic's cooling system this past April, what came out matched exactly the capacities listed in the manual. The point being that a drain, fill, drain etc. should get darn near everything old out. The drain and fill also removes a lot of sand-like sediment that can impede proper cooling or maybe bind mechanical parts. Around a 1/4 teaspoon of this came out when I did a drain and fill after about 2.5 years this past April. That may not seem like much, but ISTM some of the passages and the water pump clearances are small and could cause the aforementioned problems. (Someone else might elaborate.) Generic anti-freezes are said to cause water pump (bearing?) problems. I can't say for sure, but I know I had water pump problems after using the green stuff. Lots of folks have testified here to the same. Three years ago I switched to the orange (after a very thorough flush). I have had no water pump problems since. The water pump is currently 4 years and 60k miles old, having lasted much longer than the previous one (or two). I'll replace it in two more years, when I do the timing belt. I won't be hitting the mileage spec. About anti-freeze shelf life, from Havoline's orange Dex Cool site: "The primary limiting factor in the shelf life of a coolant is silicate instability. Since silicate will eventually polymerize to silicate gel, all traditional coolants have a shelf life of about 18 months. Havoline Extended Life Anti-Freeze/Coolant DEX-COOL is silicate-free and therefore can be stored for at least 8 years without a problem, provided the integrity of the container is maintained." http://www.havoline.com/products/na/...e_01_tech.html For distilled water, I just buy a gallon marked "distilled" at the grocery store. Dunno about the lab water. The grocery gallon is cheap and common enough. Suggestion: List the year, miles, and model of Honda you own if you have more technical questions.

If you have it in there now, you are ruining the water pump seals. Flush like crazy and fill with genuine Honda coolant. Expensive? You just won't believe what it costs to replace the pump. The photomicrographs of the damaged seals show erosion caused by the silicate. Silicate is simply sand. You might be okay with an OAT type coolant like Dex-Cool, but it has it's own set of problems like sludge formation if the radiator gets air in it. So, overfill the bottle like Texaco recommends. And check the level often. It will give you long life, but so does Honda's blue formulation. I have a minor in chemistry. The lab water is first distilled like the bottled variety, and is then stripped of the ions that remain. This is produced by a great big, stainless-steel expresso-looking machine, right? But, such pure water becomes a decent solvent, and tries to dissolve whatever it's in contact with, much more than regular water. "Nature abhors a vacuum." So, if it were me, I would actually add a cup or two of tap water depending on your local water hardness. |

My car is 2000 Honda Civic Value pack (kind of in between a basic and a LX
regarding the trim, but no difference in engine) with 69000 miles on it. The car is Canadian make. Mostly, I put in highway miles from C'ville to Philadelphia.(520 miles roundtrip) Thanks a lot for the feedback. I will do a flush and fill up with Honda Genuine Antifreeze. I am kind of skeptical about adding a cup or two of tap water to that water though as suggested by jmattis. The slightly better solvent property of the deionized double distilled water compared to distilled water is almost a moot point considering its usage as a mixture to the antifreeze. I understand that it probably is a overkill. I might use it because its easy availability to me:-) SB "Subhabrata Bhattacharyya" > wrote in message ... > My car has enough Antifreeze (green one) in the radiator but little above > the min. mark in the tank.

And make certain you pull the block drain. Do not neglect this step. There is a quart of fluid in the block that is not drained unless you remove the block drain. -- TeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

You can get Honda premixed or not. They sell both.

(It's about > half the price!) hell no. you CAN use the orange dexcool 100k mile stuff in the silver jug. either way, you should drain, run regular water thru for 10mins, drain again. THEN add a 50/50 coolant mix. some peeps here may disagree with the orange dexcool recommendation and suggest only honda coolant. your call. ive used the orange dex in a variety of aluminum japanese gas engines over the past 15 years, and have had NO problems whatsoever with anything. > 2) Is it okay to mix it with the old green antifreeze?

I just used hose water for this. we forgot to add to make sure the heater lever is full "on" for the whole procedure. that gets ALL the bad stuff out/good stuff in. |
