Dex-Cool Information from Boss Hoss

This is the response from Rad Hunsley, Boss Hoss-Dyersburg when I wrote him to ask about the criteria used when changing to Dex-Cool in Boss Hoss motorcycles.

Mike,

We changed to the Dex-Cool coolant in 2002 and have been using it ever
since. At that time (2002) many customers and dealers where and had for
sometime been asking us "Why?" we weren't using the coolant (Dex-Cool)
that GM uses and recommends in vehicles with aluminum components. We
inquired with our GM contacts and they also informed us that they
recommended that we switch to the Dex-Cool coolant. Despite the
significant cost increase to us, we decided to make the recommended
change.

Regards,

Rad


I told Rad no way was I questioning their decision to use Dex-Cool but that there had been questions arising about the use of it in our motorcycles. Mike//

I would be interested and others too I'm sure in his follow up response to you. Did you by chance forward the questions/concerns that were posted regarding Dex-Cool? Just thinking out loud but maybe he would be more specific in his answer if he had a specific question? Seems the source of his info is from GM - not exactly an independant, unbiased source for answers!

V-Man, Yeah I know what you mean. I used the form on the BossHoss.com website and sent a real short note to Rad saying that it was rumored that new bikes are shipped with Dex-Cool and when and why had the change been made? I appreciated the time Rad took to reply. I had installed Dex-Cool in my 2001 when I changed my fluids this fall and thought the Dex-Cool was a good idea since it was only a few dollars more and claims were it was a better corrosive protector and longer lasting. I did a little research on my own and most of the people I talked to seemed to think the problems had been caused from either mixing with other products or allowing the level to get low in systems causing the problems but it left me with a lack of confidence with the product and I decided to flush my system 4 times and return it to a green product that I know has worked well for many years and since I will change yearly not as concerned about corrosion protection as vehicles that would leave it in for longer periods of time. I felt kind of bad as the orange Dex-Cool was being drained that I was just wasting my money but if it turns out that the product is hard on gaskets or clogs passages over time I still think I did the right thing. If you do decide to make any changes make sure you drain and flush the block till water runs clear from it. The discussion has been a good thing though as it made others aware of importance of not mixing the two and alerted them of the possible problems.

Mike,

I'll tell you - I have been a Bos Hoss owner for a short time. I am very impressed with the factory as far as responding to questions and such. They have treated me like no other motorcycle manufacturer I have ever owned! I have had a couple warranty issues and they were ALWAYS there and always happy to help.

But ... back to the coolant issue. I have an 03 and it came with Dex-Cool. I have read of issues with Dex-Cool for sometime now so I almost immediantly drained and flushed it all out. I went with EVANS COOLANT. I have been running it in a blown Valk for a couple years now. I will give the EVANS a shot and see how the bike runs in the heat (hope I get to test it in Daytona for Bike Week) as far as temps go. Stock I was running about 180.

I did some reasearch awhile back on coolants ... more specific the mixing of coolants. You are 100% correct, you CAN NOT mix the two types. Mixing the two types will cause the coolant to foam. The foaming creates hot spots in the engine and we all know that is NOT what we want! I think changing the coolant as often as we all do (read fanatical) probably any coolant would be fine ... probably.

Thanks again for the post. I do hope that Rad may add some information that we may not have or know about.

V-Man,
Do you have the links to the info regarding the problems with Dex-cool. I got the information on the other site from the dex-cool mfg that includes commenly asked questions and tech info. I was looking for some unbiased reports and info. BTW did you find a buyer for your Valk and how was the show.

I am sure I have the links and info on Dex-Cool on my old computer. I will try and boot it up this week and pull the link off for you.

Bike show went well - two trophies - second place in class (special interest) and then best engine (show). Lots of great looking bikes there ... if you can't ride the next best thing is to be at a show looking and talking about riding! Here is a link with a few pictures http://www.v-man.org/NE Expo 04.htm I did not take too many :( There was lots of intrest in the Valk but no money exchanged hands ... one guy is trying hard to come up with money so we'll wait and see.

Congratulations - your famous! I read your article "Cold Weather ... Keep Riding" in BH Country :D :D :D EXCELLENT
V-Man,
Good pics. Bike looks good. I think that bike with the DVD was at the Javitts Center out front a few weeks ago at that show. I haven't got the Hoss Country Magazine yet. I probably shoulld get with-in a few days. Good Luck on that sale. Also thanks for looking into that Dex-cool info.

Evans Coolant

V-Man

I called tech support at Evans coolant to ask them specifically about my Boss ('97) which was overheating. The support guy was quite familiar with the underdesigned radiator problems of some Boss Hosses and said that their coolant WOULD NOT provide any benefits in that area.

I don't know whether it would be OK in a Boss without overheating problems or not. I guess you'll find out if the weather ever warms up in Maine. :)
Jim

I hope the weather is HOT in Daytona ... anything over 65 is hot :wink: It is good to know that EVANS did not/would not sell you something they knew would not correct the overheat problem. Do you have the stock radiator or did you upgrade to larger capacity? What type of waterpump is on the 97 - same set-up as todays? Hows the new engine coming along ... Does Jane want her own Boss now :) ?
