Plz do NOT mix different coolant colors. That will gum up entire system! You can dilute & just add water (preferably distilled) to whatever brand, just so long as it is safe for aluminum. If you can’t find a matching color, then drain, flush copiously with water, then add the new stuff. TThere is a drain plug on the radiator, but there have been multiple reports of it snapping!


You can also remove the lower hose if you have a replacement strap/clamp, as the OEM clamp usually has to be cut. Hope this helps.
** Flushing can be done with tap water - just catch it all & dispose of it per EPA guidance properly. **
