Default heater hose list.

All;
I wanted to gather all the hoses together in advance for a preventative replacement of heater hoses. There is a minor leak now. I wanted to be proactive, so the car doesn,t sit for weeks waiting for something like I just did for a coolant crossover pipe. I already have the octopus. Does anyone have a list of the hoses. Car is a 98 xk8 convertible? Thanx in advance for help.
Don

From my list. I think this is all of them:

Bleed hose MJA4560BE
Bypass hose NCA2213AC
Lower rad hose MJA4515AD
Upper rad hose MJA4500AE
Coolant reservoir MJD4400AB
Crossover pipe AJ85885
Heater hose MJB6720AC Note this replacement looks quite different from the original
Heater hose MJA6721AG
Heater hose MJA6739AC
Hose NCA3976AD
Octopus MJA6728AC
Part load breather AJ84880
Tee piece NNE3944BA
Thermostat Tower AJ82217 (Aluminium replacement)
Valley hose 1 NCA3945CD
Valley hose 2 NNE3946CA
Water pipe hose NCA3246AB

Some are around the heater pump if you're doing the deep dive.

I keep a spreadsheet listing all the parts I've replaced, when and the cost. It's just handy as a lookup for the usual suspects
