L322 TD6 AC Belt automatic tensioner is seized, Belt is slipping, Pulley is free to rotate but tensioner will not move seized.
Is there a tensioner replacement procedure available? Current Vehicles: 2004 RR Td6,) 97 Nissan Terrano 2 SE (Old Reliable) , 1989 Merc S 260SEL, 79 XJS V12 manual, 85 VW Sirocco GTS

Is it the one at the bottom of the engine around the oil sump area?

If so it's a common fault and an easy repair

The others are up in the area of the water pump and not so easy to access

Should be number 2 next to the blue belt in the image below

Hi Thanks for the response, The Tensioner is the bottom one, No 2

The rubber outer seal on the tensioner shaft had been split! So time to replace the whole unit I guess. Current Vehicles: 2004 RR Td6,) 97 Nissan Terrano 2 SE (Old Reliable) , 1989 Merc S 260SEL, 79 XJS V12 manual, 85 VW Sirocco GTS

I currently have my Ac pump out and in the bench for new bearings and I think I'll replace my tensioner too provided it's not gonna cost an arm & a leg!

Hi Thanks for the prompt response.

Is there a procedure for removing and replacing the tensioner and is possible it be carried out with the AC still in place? Current Vehicles: 2004 RR Td6,) 97 Nissan Terrano 2 SE (Old Reliable) , 1989 Merc S 260SEL, 79 XJS V12 manual, 85 VW Sirocco GTS
