Hello
Need help pinpointing the hose to replace

It's that reinforced hose, supposed to be fitted, I had it replaced with some extra we found


Here is vovlo direct oem chart, am thinking it's 24, 25

 

Not sure but it looks like #24 to me

 

If that hose is leaking, at that age it won't be alone - why not replace at least everything in the vicinity?22 -25. It may cast a bit more but then you know that the next leak isn't there. Honestly, I would just do the radiator hoses and 13 too. Flush the system as well. Then do the heater hoses. Sounds excessive but you won't have to worry abot a but coolant hose for the life of the car!


Then you can start on vacuum hoses.................
