1999 Jimny Heater Core Hose was created by Reason2doubt
Hi everyone,
Just about to flush my heater core as one pipe is significantly colder than the other leading me to believe it is blocked to some extent however I've been wiggling the inlet hose to see if they were stuck and it started to disintegrate and now leaks a little. I would like to replace both of them if possible.
Would anyone happen to know the inner diameter of the hose I would need (pictured)? Edit: or know a suitable replacement?

Surely the ID of the rubber hose is the same as the OD of the steel pipe it's connected to?...

Yes, fair point. Just wanted to ask in case there was some hidden wisdom out there...

Whats been said ^^^^.
Measure the OD of the metal pipe and get a rubber hose with a ID no larger, ideally slightly smaller, than the metal pipe OD.
Only other option is new OEM pipe I suspect.

Be careful about how you manipulate the metal pipes as when they move relatively to the heater matrix they can start leaking. Unless the older ones are different the pipes are kinda crimped into bosses on the core and disturbing them after years of immobility is not good.
