Can you replace both sides of the heater core Lines or do you have to buy the whole part. I know you can replace the front lines but can you replace the tow that are on the heater core? And do you have to buy the molded hoses? It almost looks like you could get away with just using regular hose the bends don't look that bad.
Let me know what yaw think.
Thanks,

 

You can replace individual hoses, if you have room to deal with them. Molded hoses would fit better. It is a bit of a pain to install, but I would buy and replace the whole hose assy.
