Re: Cooling system hoses
The coolant doesn't get very hot so there isn't much thermal or pressure stress on the hoses. Unless you've somehow abused them, I doubt that new hoses are needed. All I see in the service manual is to periodically inspect them. I still have the original hoses on a '69 Corvette, which admittedly doesn't get driven much, and they're still fine.
As the Geek says, the larger hoses (even the crankcase breather hose) are formed. You're not going to find them at Pep Boys, etc.
