While a work party was attempting to change the water pump on an XKR it seemed there was little room to relieve the tension and remove the supercharger belt. There is an electrical connection but at its age we were afraid to force it too much and it was very difficult to reach. It became clear a special tool would be handy and as we envisioned the tools shape we looked through our un-numbered tools. We came across the below and in fact it is exactly what the tool is for. Amazing how easy the job became. We have now found the tool number (on the yellow handle). Now to identify the smaller tension tool!

 

 

Thanks LTD--we will go to the JTIS and find it! (not Snap on)
