I'm interested in replacing all the radiator and vacuum lines in my '93 Loyale along with the PCV and EGR in order to solve problems with rough idle and hesitation as well as ensure no coolant leaks or vacuum loss due to old/cracked hoses. 

 

Where can I get the hoses for this, which are they, and how much would it cost?

 

Thanks.

I've gotten all the cooling system hoses from NAPA.

 

The PCV hoses, dealer, or find generic hose rated for that use.

 

The small vacuum lines, generic vacuum hose.

 

No idea what all of it would cost.

That is an excellent maintenance step. You will find for the smaller preshaped hoses, Subaru doesn't carry them and third party parts places will not be able to offer the exact same size hose, but rather close substitutions. Just be sure that you get the correct hose type for the task, eg coolant vs fuel vs vacuum.

DaveT and MR_Loyale, thanks for the info! I wondered if generic tube would work if cut, seems that it will. I'll see what I can do between the local NAPA, Autozone, and O'Reilly's stores. I'll update you on how it works out.

Generic is fine, just be sure to use coolant hose for coolant, vacuum for vacuum, etc.

 

Only 1 piece I know where ordinary straight hose won't work is the small elbow off the top of the water pump to the heater hard line.  It's a 90 degree elbow.  NAPA has one that fits.
