I'm a little late jumping on to this thread but some of the points are relevant to my question.
I have a 1600 Vauxhall Caterham Classic (carbs not injection) and during recent MOT the bottom radiator hose was seen to have a few cracks. Close inspection of top hose also shows some cracking so intend to replace both. From a quick trawl of the internet I couldn't find replacement rubber hoses but noted lots of references to silicone hoses. Apart from 'lasting longer' and initially 'looking prettier', I couldn't see much benefit of silicone hoses; it seems there may be a couple of negatives such as larger diam - therefore needing different clips - and possibly having to top up the cooling system more frequently.
Does anyone have any views re pros and cons of silicone vs rubber cooling system hoses? Also, if rubber wins the day, does anyone know where I can buy them from?
I look forward to your advice.
