'Replaced my upper radiator hose a couple of months ago. The dealer wanted $150 for the part. I opted for the hose only from a local autoparts store for $10. The OEM clamps were a PIA to remove but got it done and replaced the clamps with screw type. Also had to replace the small plastic hose on the filler/reservoir tank as it broke while I was doing the repair. I replaced it with 1/4" copper tubing which will be much more durable unless of course there is some negative interaction with copper and coolant.
