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 The previous version was outdated and no longer supported.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

new TE250 -- no coolant!

The one on the rear fender is temporary. It flies off with the first wash. The stickers were placed there by the factory.

The 2010 TXC250 doesn't have one, I traced the overflow hose and it ends under the skidplate. For some reason I thought street legal (TE) versions were required to have a recovery tank. Did you overheat the bike initially before discovering the low coolant level?

No, and the fan did not come on either.

I assuming the temp sensor in the coolant system is in the motor. I don't see any wires on the radiators.

I circled in crayon what is believe to be the mechanical thermostat.


Pretty sure there is an actual thermostat in this new 250 series. The fan should be actuated by a temperature transducer located in either the fan assembly or maybe using the coolant temp sensor with the EFI loop.

Here's a clip from a cold start on my '10 250. No coolant moving outside of engine vibration.

Here's a clip after a little warm up. Coolant starting to rise and swirl at around 100F.

Interesting stuff. This thread sparked my curiosity. The cooling system is a little more "busy" than previous years. More lines in the sytem now and I still don't know how they all work together. :busted:

Yes, you can see the return line to cycle the coolant back to the motor when the T'stat is closed.

I believe that it why I saw no flow at the rad with a cold motor.

I need to heat up the motor when I get home and see if it flows.

I see there is no bleed screw either...you drain from the hose. I guess if you just poor some coolant in an air pocket may form causing an unfull condition
 
I ran it today. After about 5 min I could see the some flow in the radiator and they started to heat up as well.

I just added some distilled water and will leave it at that.

Motor still seems very tight.
