  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Better Coolant For My TE-449?

I'm actually starting to get a little concerned. This bike has always run hot -- to the point of boiling gas. And with summer approaching, things are only going to get worse. If the fan is running constantly in 50 - 60 degree temps, what's going to happen in 90 - 100s?

You can send me a copy of your pc5 map and I can advise you. Do you have the accel pump turned on? What grade of fuel/additives are you using?

Accel pump on, though I'm not sure on the numbers. I recall they were base on my earlier understanding of the settings. I use stabil marine at the recommended maintenance amount per 5 gallons (either .5 or 1 ounce). And 4 ounces of Torco per 5 gallons. And always use Shell 91. I'll pm my map tomorrow evening. Thanks!
 
Just the drop in pressure in the cooling system has had me sold for a long time. I have been running waterless coolants on several bikes over the years. All good for me.

Maybe Tinken can chime in and give us an approx number for the pressure drop in the cooling system. I think I read somewhere it was from 20psi to 5psi. Please correct me if I am wrong.

If it's XF2, typically it's only 1-2 psi due to the thermal expansion, at most 7 psi but you would have to have it pretty hot to get that high.

I'm working on an new additive that can be added to XF2 or any other coolant for that matter which will boost the temperature up to as much as +600°F. When added to XF2, it becomes purple. Still a few months away from release.
 
The coolant doesn't corrode, it's the water that is the problem. Even EngineIce contains 7% water. We used to use Evans, but at 2% water, it would still over boil in extreme conditions. Our XF2 is anhydrous and contains only trace amounts of water. Like synthetic oil, the purity of your coolant will increase it's performance.
Properly maintained glycol coolant won't corrode either. Mine is two years old, and due for a change.
No signs of corrosion.
I appreciate the Evans doesn't require changing as mentioned, but I have no cause for concern with the standard cooling system.
Fan run very occasionally after lots of clutch work on hills, otherwise, it looks after itself.

The title of this thread is "better coolant for my TE449" so I'm guessing he is asking about alternatives to standard antifreeze. He is asking if the XF is better in some way and worth it. It has a much wider operating range, runs at lower pressures and has no water in it which is known to corrode aluminum. Those are the advantages. Does antifreeze work fine? Sure. So do stock tires. He is asking about an upgrade.
 
I'm going to be up at Mt. Shasta in two weeks for the Western Hare Scrambles, I can bring it with me if you want?

Thanks for the offer, I really appreciate it. I actually ordered it last week. The lady that took my order said shipping is only going to be 5 bucks.

I am going to be putting all the stuff I bought from you guys at zip ty this winter on this Sunday. I can't wait man. I should defiinitely notice a big gain in performance with the ecu remap and pc-5.

Where are the Western Hare Scrambles going to be at, and what date?

Are you going to be staying in Mt. Shasta? If that's the case, I'd like to buy you a beer.

Let me know, thanks again.

I love how Erek puts the ZipTy logo right next to FMF, like we are constantly battling each other.

The title was indeed 'better coolant ', yes.
No mention of XF or Zipty branding at all.

The factory fill coolant is rubbish, a better, readily available coolant is what I mentioned. The Nissan product is very good.

There are other products available, this is an open forum not a paid advertiser thread. By yours & others description Evans works too.

Thanks for the shut down.
 
Haha, Kelly is a good rider, probably roost me.
Yeah I know that's why I'd rather send you. If you and your crew needs any info on places to stay while your up here let me know I'll try and help you out. I know all the dealers here and who to contact if need be. Some places are better to stay at than others.

It wasn't a shut down, just revisiting the original topic.
Evans does indeed work, I have been selling it for years. In recent tests where I boiled both XF2 and Evans, the Evans turned dark brown from deterioration, while the XF2 remained clear. I suspect it is the propylene glycol (PG) in the Evans that is not tolerating the heat as well, I'm sure EngineIce would react the same since it is made entirely of PG. Is there a better coolant? To date, XF2 is the best coolant that I have found. Being that it is less than the price of Evans, makes it a pretty good value.

No reason to get upset. Yes, evens, XF, water wetter... were discussing all of them here. Was not trying to shut anything or anyone down.

from the OP...

Is the XF Coolant I see on the site worth the money?

Which one would you recommend?

XF+ Race Coolant or XF2 Coolant?

I dont think I was out of line at all and not sure why you took it that way. All good.

Ok, my apologies, obviously I missed that as I came in a page down the thread and added to the mix.
 
I'm actually not sure what's available down in AUS and I know my coolant is expensive to ship to you.

Nissan and Honda coolant is identical. The original formula for these coolants came from Prestone. Prestone no longer uses this formulation and basically omits the Sodium Nitrite/potassium hydroxide inhibitor package. Sodium nitrite is added in order to counter the ion pull from iron based components in your engine, making the coolant more universal between engine types. However, sodium nitrite reacts violently with aluminum and deteriorates the other inhibitor. So what Prestone did recently was change their inhibitor to di-potassium hydrogen phosphate (DKP). I like dkp, it reacts very fast to coat aluminum and not allow the ion pull. We don't have much iron in our motorcycles so it would be better to find a coolant which eliminated the sodium nitrite if you were going to continue using this type of coolant. Ultimately to stop the ion pull is to just remove the water out of the equation all together, no water, no ion pull, no corrosion.

I would assume Nissan Australia & US use the same suppliers.
I have personal long term usage history with this particular coolant. (The reason I posted)
Several vehicles, two with well over 200,000km.
One all alloy engine with alloy radiator, one iron block with brass radiator. Multiple rally cars & now my dirtbikes.
I've never replaced a welsh plug, radiator core or heater pipe on any of these cars, nor had any kind of corrosion/erosion in the bikes.
Indeed, the rebuild of the iron block/ alloy head engine was an eye opener to me.
The coolant ports in the head were perfect, the bypass pipes looked new, I punched out a welsh plug and but for the fact that I now had a screwdriver hole in it, it could have stayed in place.

I must say that I'm a little confused by your concerns.

I didn't jump on to hijack the thread, I've had a great run with this product and thought I'd post it.
I'm sure others have had good success with other products too.
