I bought Gates upper & lower radiator hoses and Volvo heater hoses. There are fittings on the heater hoses at the firewall.
I'd just like to know the lifespan of the hoses to the oil cooler. They carry coolant to and from the cooler.
As parts go they are quite expensive.
Is your V70 a turbo? If so, be sure to replace the turbo coolant inlet hose on the back of the engine.
See here for a nice walkthrough on replacing the radiator/turbo coolant hoses.
For the heater hoses, be careful when removing from the coupler in the firewall. The coupler isn't too expensive (
see here), but it is a pain. I went ahead and bought a spare to have as a backup just in case.
Leave the oil cooler hoses alone - when they fail, they start leaking very slowly (usually from the crimps). The late-model (post '00, I think) has a much more reliable oil cooler design (from what I have read/seen) than the earlier style. I just replaced the oil cooler hoses on my '98 XC at 150k due to oil leakage. They had been leaking since ~140k...verrrrryyyy slllooowwww.
Lastly, order your OEM parts from
VolvoPartsLisle - much cheaper than going to a different dealership and paying their massive mark-up. If you need part numbers, go to a website like FCPEuro, EEuroparts, or IPD and grab them after finding the part you need..
