Just to close this one away .... got the relevant "book of lies" and after 3... yes.... 3 visits to the renault dealers I eventually got a belt that fits ... even with Registration no, VIN and Engine No they managed to firstly give me the aircon one then one that was too short ..

Unfortunately as she had "lost" the original I had nowt to compare with and had to take their word for it ... bunch of numpties ..

Job was a bitch .. not technically difficult, only a total of 1 screw and 3 bolts... but there is just no room to work ..
My Torx set were WAAAY to long for the space I had, so down to the motor factors and, luckily, found a torx bits set like a set of allen keys (?) ... with these I was able to loosen the screw off, release the aircon belt tensioner, and remove the aircon belt. 2 bolts on the alternator .. one of which is impossible to see ... so all done by feel. On with the new belt, do it back up then put the aircon belt back on.

Haynes then talks about some specialist tool for getting the tension right, that can only be done at a main dealer .. sod that ... belts are tensioned to 1/2 inch play at centre of longest run... just like I've always done

Forearms are raw from working in such a confined space, but job is done ..

SWTSMBO has been lectured on the meaning of the word "STOP" when it comes on in big red lights !!! Will she listen ?? ... doubt it ..
