id pay to see it done in 2mins tbh
when i went to see forge test fitting a coolant kit on a golf, it took more than 2 mins to empty the system! plus if its not cold ul come away with more than just scraped knuckles! its really not easy to get to, break the securing clip, pull pipe off, disconnect it at the other end, then could take up to 10mins just to get the new pipe on!
as said, the new hose only cost about 35quid, the coolant itself was about 18quid, then a flush, plus labour
and that wasnt even a stealer!
2min job?! pah! not even if ur the new superman!
but no more than 35/40mins eiither
