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 The previous version was outdated and no longer supported.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

TE 570 overheating

Any suggestions on how to keep my 01 TE 570 from boiling over? I ride at sea level to 1500 feet elevation on the Oregon coast, it only happens when I am doing a bunch of tight slow going trail riding in first or second gear. I have flushed the cooling system and have put in "Engine Ice" coolant and it helped but will still boil over after doing some tight slow going riding.:excuseme:
 
You can always try a higher pressure rad cap. For example, if you have a 1.2 bar, you can go up to a 1.4 bar.
For every couple points in pressure, you increase the boil-over point by about 20-25 degrees.

Hell, you may just need a new cap... your eight year old one may be out of spec.

For sure restrictions to air flow will hamper cooling ...whether its braces/guards on the rads or even those slanted louvers bikes sometimes have.
But check for something as simple as too many of the little fins between the vertical coolant tubes being mashed over. Seriously, a lot of them closed off is deadly to cooling. Remove and rinse the rads, then sit down in front of the TV and spend two hours picking the fins open with a razor knife or equal. ( Don'r "saw" on the vertical water tubes with the blades sharp edge... your just using the sharp narrow blade to pick the fins open).They don't have to be perfect...just open for air to pass. On the spots that are mashed too deeply to open up just push clear thru the rad with a very small screwdriver. (Better to have no fins there than fins not letting any air thru...... seriously).

If you've never replaced the rad cap. That is where I would start. The stocker should be able to handle 1500 feet. If it keeps it pressurized in the rad., you won't have to worry about the elevation. If it's not the cap, then you probably go a leak somewhere like the gasket (as previously pointed out).
