• 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 The previous version was outdated and no longer supported.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!

Does anyone know the PSI/BAR of the cooling system? Here's why...

Hi gang. Last weekend my radiator went bust- seems to be a common issue w/ these Alexon radiators. A great dealer sent me one straightaway- can't thank them enough.

Now, upon looking at it closely last night I see some pretty significant damage to an area of the fins...enough to have moved a few off their tiny spot welds. This concerns me, obviously, as the old one sprung the leak along one of the downtubes where the fins meets it. If I close one end and blow really hard on the other it seems to hold pressure, but we know this couldn't be more inaccurate of a method.

I'm going to e-mail the dealer- he's great so I'll see what he says. I'd really like to repair the bike tomorrow (which is why I paid for 3-day shipping) to recover a ride. I'm considering taking it to a radiator shop today to get it pressure tested- but I do not know what they should "pump it up" to (and then they see if it holds consistent pressure, of course.) I want to specify a range to them so they don't blow it.

If anyone knows the safe pressure range please let me know. Thanks!

isn't the cap 1.4bar? (thats the indication to what to test it there)

to pressure test radiators you pump to or just above cap release pressure
 
also on the reason on why aluminium radiators leak is usually because the weld/solder between the tubes and the tanks (where they meet - the weld is on the indside) if it isnt leaking there the only other reason would be a pinhole i assume
 
My Alexon radiators always cracked up the center of the coolant tube, not near any weld. I think that it was because of vibration that came through the closest mounting point.

I had it welded up, but it leaked again. After that I bought a Toyo replacement and never had any more problems.
 
This is helpful- thank you both very much.

Maxyb- good point. "Duh" moment on my end....didn't think to have a look at the cap.

Dirtdame- What else can you tell me about the Toyo (part number...where you got it?) When/if this happens again I want to be prepared to go w/ another brand.

Thanks!

It's a Husqvarana part that can be ordered from any dealer. It's on the microfiche.
