Here's the official Honda bulletin on WHY to use only OEM Coolant:

"Increasingly severe operating conditions and the advent of lower maintenance requirements have resulted in significatn changes in the variety and the concentration of additives used in engine coolant. Also, the continual improvements in engine and vehicle design have challeneged coolant suppliers to design products that perform well in a more demanding environment.
To meet these needs, Honda R&D Engineers have developed a superior, high quality coolant that has several advantages over the competition.
Some antifreeze, although labeled safe for aluminum parts, may not be compatible with Honda/Acura cooling system components. Extensive research and testing by both Honda R&D and CCI, the manufacturer for Honda coolant, have proven that the abrasive silicates and/or borates found in most all domestic coolants can cause the following problems:
*Silicates bond to the surface of Honda/Acura water pump seals and act as an abrasive, causing considerable seal erosion and eventually, coolant leakage. In actual tests, the silicated coolant caused early leakage. This leakage increased dramatically until a substantial portion of the coolant had been lost. In contrast, the OEM Honda coolant has NO leakage through the entire duration of the test.
*Silicates tend to gel and settle in the coolest part of the system, causing radiator plugging and overheating. Honda coolant does not do this.
*Borates cause pitting and corrosion in the cylinder head and cylinder block's water jackets and passages.
*Silicate inhibitors are difficult to stabilize, and therefore limit coolant shelf life.

Honda coolant was designed specifically for aluminum 4 and 6 cylinder engines. It contains an organic corrosion inhibitor instead of silicate, which displays excellent characteristics:
*No silicate abrasion of water pump seals.
*No plugging or overheating caused by gelling.
*Excellent corrosion protection for aluminum components
*Long-term corrosion protection for other cooling system materials( steel, cast iron, copper, solder, gaskets, seals, and o-rings)

You may find less expensive coolant brands on the market, but now you see why Honda is the only way to go. This is the ONLY coolant approved for warranty repairs. Honda's non-silicate formula delivers added protection not offered by 95% of other brands. Since our customers expect lower maintenance, you're doing them an injustice if you use any other coolant.

Pretty cool, huh guys!

 

pretty cool!
i'm glad i used the oem honda coolant! just did my upper and lower radiator hose this weekend. i flushed the coolant and changed it with the honda pro coolant.
thanks for the info...

 

how much does this spiffy coolant cost?

 

i only put water in there...will my car be ok?

 

 

Its pretty expensive from what I remember...like $15? Or is it $9? Hmm...

Either way...its not that bad...not like you change the coolant every month or something.

 

Suggested retail is $15.85 per bottle of coolant, I sell it for $10.63 per bottle.

BTW, this is the Type One coolant. The new Type Two stuff CANNOT be mixed with any water or additives. It is formulated to go directly in, it's premixed.

I use the Type One so a more watered down mixture can be achieved.

 

that's my picture! lol i was like hey that looks familiar....i paid i think 10 plus tax for mine at the local honda dealership

 

 

Is there only one kind of coolant Honda sells??OR do i have to ask for a certain one.

 

Tell them you want the old style Coolant. Not the Type Two coolant.

Part number you're looking for is CU08730.

 

good info mike!!

 

Fo reel, thanks for taking the time to help everyone out

btw did you ship out my coolant reservoir yet??

yea it went out last week.. so did one of your RS door handles. the other RS door handle is still on backorder. i'll email you when it comes off backorder.

 

Thanks - doh! you'd think they'd be in relatively equal supply

 

mike k is it okay to mix type one with type two? The reason i ask is because i did some front end damage to my car and my radiator is leaking very slowly. The coolant resevior was at the min mark after about a week so i added some type 2 coolant to the resevoir. i noticed the type 2 is more of a green color compared to the type 1 bluish color. i haven't drove the car yet since i added the coolant, but need to drive it to the body shop this weekend.

 

Deos Acura dealer use the OEM Honda coolant when they do service to our cars?

 

No they use Prestone. Prestone is better.
