Coolant Change - how's it done on a Ryker?

[Peter Aawen]

The Ryker does not have a drain plug or hose at the bottom of the radiator. How do you drain the old coolant?

Inquiring minds need to know.

There's gotta be a hose to let coolant flow IN to the radiator, and a hose to get coolant OUT of the radiator; so as has been mentioned, taking the radiator out & tipping it upside down will almost certainly take care of getting all the liquid coolant out of that!

But it's still a very good idea to use a hose with some water pressure to back flush the radiator (but DEFINITELY DO NOT use as much pressure as that pumped out by a pressure sprayer! . Your normal garden hose pressure as a maximum should be fine. ) And while you've got the hose there, spend some time back flushing the engine as well.
