Any brand that u guys might reccomend. Going along with my other post, I plan to flush the whole radiator and clean up everything, including using new coolant. This Pennzoil crap doesn't cut it. Hopefully my problem will not return. Thanks guys.

 

honda

 

That's what I've been using but had no idea I was supposed to use distilled water

 

Honda all the way OEM for me

 

I'm pretty sure a lot of people use tap water. good thing that i just found out, knowing is half the battle!

 

what did you use sping water. is there a big deal between the 2.

Honda antifreeze sucks.
I use the cheapest stuff from walmart. Usually the stuff in the yellow bottles,
maybe thats prestone.

 

distilled water and whatever's cheapests at the local auto parts store.. (that's still a "Brand name" I've never used DAP anti-freeze yet.. maybe in my next b00sted ka.

 

Genuine Honda coolant. This information was sent by Honda to all its dealers, and this is why I use it:

Genuine Honda Coolant is the Only Way to Go

Increasingly severe operating conditions and the advent of lower maintenance requirements have resulted in significant changes in the variety and the concentration of additives used in engine coolant. Also, the continual improvements in engine and vehicle design have challenged coolant suppliers to design products that perform well in a more demanding environment.

To meet these needs, Honda engineers have developed a superior, high-quality coolant that has several advantages over the competition.

Some antifreeze, although labeled as safe for aluminum parts, may not be compatible with Acura cooling system components. Extensive research and testing by both Honda R&D and CCI, the manufacturer of the Honda coolant, have proven that the abrasive silicates and/or borates found in most domestic coolants can cause these problems:

- - Silicates bond to the surface of the water pump seal and act as an abrasive, causing considerable seal erosion and 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 Honda coolant had almost no leakage through the duration of the test.

Chart here, entitled "Coolant Leakage from Water Pump Seal", showing Leaked Coolant Volume in ml as follows for each test duration in Hours:

24 hrs: Honda Coolant 0, Typical Silicated Coolant 21
48 hrs: Honda Coolant 1, Typical Silicated Coolant 36
72 hrs: Honda Coolant 2, Typical Silicated Coolant 47
96 hrs: Honda Coolant 2, Typical Silicated Coolant 55
120 hrs: Honda Coolant 2.5, Typical Silicated Coolant 56
144 hrs: Honda Coolant 3.5, Typical Silicated Coolant 57
168 hrs: Honda Coolant 4, Typical Silicated Coolant 58.8
192 hrs: Honda Coolant 6, Typical Silicated Coolant 63
200 hrs: Honda Coolant 6, Typical Silicated Coolant 64

- - Silicates tend to gel and settle in the coolest parts of the cooling system, causing radiator plugging and overheating.

- - Borates cause pitting corrosion on the cylinder head.

- - Silicate inhibitors are difficult to stabilize and, therefore, limit coolant shelf life.

Most commercially available coolants were originally designed for cast iron engines. Silicate, an inexpensive additive, was added to coolants to prevent aluminum corrosion, but the long-term durability of the combination was not tested.

In contrast, Honda coolant was designed specifically for aluminum engines. It contains an organic corrosion inhibitor instead of silicate. This superior formula gives these advantages:

- - No silicate abrasion of water pump seals. For example, these graphs show the surface roughness of two aluminum water pump seal rings. Seal A, exposed to silicated coolant, shows considerable damage. Seal B, exposed to Honda coolant, displays only minute wear.

[graphs here, showing roughness across the surface, with A a very wiggly line, and B a very smooth line]

- - No plugging or overheating caused by silicate 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 can find less expensive coolants on the market, but now you can see why genuine Honda coolant is the only coolant approved for Honda and Acura vehicles (it MUST be used for warranty repairs). Honda's non-silicate formula delivers added protection not offered by 95 percent of other brands. Since our customers expect lower maintenance, you're doing them an injustice if you use any other coolant.

 

Just changed mine this w/e.

Honda 2.

Never mix brands.

 

I for one do not trust anything a honda dealer or honda america says.

 

Just a few questions:

>When does everyone flush and change their coolant (I'm not by my manual )?

>What bar does your temp gauge rest at when fully warmed up? Mine sits at half-way...

 

>When does everyone flush and change their coolant (I'm not by my manual )?

First change 45,000; second change 75,000; third 105,000 (or until out of spec, I check at every other oil change).

>What bar does your temp gauge rest at when fully warmed up? Mine sits at half-way

Stock sits just below half.

After further observation, my temp gauge reads just more than a hair below half-way... and that's with the spoon radiator cap...

 

Honda coolant cause it's pre-mixed.

 

Mine wasn't

 

What about RedLine's WaterWetter?

 

Honda OEM for EVERY part that needs to be replaced

-Rage

 

I went to Courtesy Honda in Memphis and asked about Honda coolant at the parts counter... the guys were like huh? why waste your money on that, we don't even use it here in the shop

I hate going to that dealer for parts, I'll probably go to Covington Pike Honda next time.

 

This might be one of the 5%...
Prestone 5/150 Extended life has no Silicates, Borates, Phospates, Nitrites, or Amines according to the label.

 

Anyone try this stuff that boils at around 320 degrees F,
is not diluted and is supposed to be run with a 3 psi cap?

I heard about it from a friend guy with a tt-7 (FD3?)
He's on his third motor soon (done with the second one),
and is having cooling problems ever since upgrading to
Peter Farrell specs with an Apex-i Power FC computer.

 

I was wondering the same thing. Check this out

anybody got the part number for Honda coolant?

correct me if i'm wrong. i think there are 3 different one.. right?

1
2
3?

 

And which one of these is pre-mixed?

 

I've been using Water Wetter for the longest time. Had no problem at all. My work uses it on all the Supras and turbo cars and the water is slightly cooler. It works better if you drain all the coolant from the block, but if you live in cold areas or have AC, RedLine recommends at least 15% coolant . If you have have no AC and live in CA, you have no need to mix 15" coolant with WaterWetter.
