Give the guy a break...tight quarters and a lot of work. This metal pipe sits just above the starter. If you do your homework as for our 2007 CR-V, we ordered HONDA parts (1) Pipe, Heater #19510-RTB-000 and (2) Grommet #91315-PNA-003
If for whatever reason you can't source #19510-RTB-000, the pipe for the Honda Element is nearly the same, at least enough so that it's usable without any modification.
I just pressure tested a customer's 05 CR-V and his ruptured on the left just in front of the rubber hose from the heater core. It requires several hours. I just called Honda to get the pipe. I would recommend changing the hoses as well. If you have replaced the starter before, it's not that bad.
I did this repair on my son's 2008 CR-V a few years ago... Several rotted out spots on the one pipe. Not being a car mechanic, it was a lot of work and pretty daunting. Also, at the time, due to the pandemic an global shortages, the cooling pipe was nowhere to be found. I substituted the nearly same part from the Honda Element. Got it done after several hours of fighting with all the rusted fittings (it is a New England vehicle, so EVERYTHING is heavily rusted/oxidized). Fast forward to last week... Had to replace the starter on the same car, thanks to what I went through for the cooling tube, it went pretty quick and relatively easy. Didn't replace any hoses... But I did replace the thermostat and housing, as well as most of the hose clamps and hardware. Used non-metallic "anti-seize" on all the bolts too after struggling for two hours trying to remove the intake manifold bracket bolts.
