I have a car I can do that stuff with now so filling requests like this is much easier however finding the time to work it into the schedule is another story. Your request is noted thank you.
You’ll need 2 bottles. All you need do is remove the return line to the reservoir and run an extension from that into a container, run the engine till the system runs dry and then shut down ASAP, refill the system and you’re good to go. Of course use Honda fluid only.
what size should the extension be? not length but diameter. I’ll have to get that while I’m out, since I don’t have any supply of hose lying around the house.
Whatever fits, you might take a piece of the old hose with you, perhaps the one that goes form the pump to the reservoir. Sorry I don’t know the exact size off the top of my head.
