For some reason my bottom hose clip (1.8TQS) looks like this (onto radiator) Bleurgh! looks at that. No idea why its so rusty, nothing else is! Two questions - 1. Is this the right part: VW AUDI SEAT SKODA RADIATOR HOSE RETAINING CLIP 1J0121142 x 2 GENUINE NEW | eBay 2. Can i pull out the old clip (probably in bits) and insert the new one without draining the system?
