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 The previous version was outdated and no longer supported.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

How to flush/change coolant?

I have searched high and low on here and elsewhere for a 'how to' guide on flushing the coolant and found nothing specific for the TR650. Having consulted the resources for the BMW 650, I have done the following:

1. Removed the radiator cap.
2. Removed the bolt from below the water pump which drained about half a litre of coolant.
3. Removed the water hose from the cyclinder head which feeds into the lower part of the radiator. Perhaps another 100mls of coolant drained out.

Clearly there is a lot more coolant to drain as the manual States that the cooling system requires just over a litre of coolant. One of the guides I consulted for the BMW GS650 indicated that to get a full drain the thermostat has to be removed from the radiator. Could this be the case for our radiators too? If so, how is it removed?

Thanks for any advice!

UPDATE

I managed to dig up an old post which covers off on the factory manual instructions. And when I actually measured the coolant drained from the bike it was almost exactly 1 litre.
