sebgreen Posted May 25, 2012 Report Share Posted May 25, 2012 Hey , Want to replace my belts and tensioners as getting a bit noisy..... There are two, one for aircon belt (left side) and one on other ancillary belt (right side). Are they both the same tensioner? As on ECP I can not tell which is which. Any help would be much appreciated. Thanks in advance. Link to comment Share on other sites More sharing options...
Matt_S Posted May 25, 2012 Report Share Posted May 25, 2012 (edited) Realoem shows them to be different. http://www.realoem.c...615&hg=11&fg=18 One thing you could do is to run the car without the AC belt on, this would eliminate the AC tensioner pulley Edited May 25, 2012 by Matt_S Link to comment Share on other sites More sharing options...
PeterH Posted May 25, 2012 Report Share Posted May 25, 2012 Before you buy, make sure you check and see if you have the hydraulic or mechanical tensioner. There are two types Matt_S 1 Link to comment Share on other sites More sharing options...

Will do that. Before you buy, make sure you check and see if you have the hydraulic or mechanical tensioner. There are two types Mine are mechanical. Just waiting from price from stealers as ECP dont seam to have AC tensioner or Deflection Pulley. Link to comment Share on other sites More sharing options...

Matt_S Posted May 26, 2012 Report Share Posted May 26, 2012 I was just hoping they put a chair behind him before he hit the floor with a thud! SHouldnt be a bad job to do. Belt replacement is easy enough, so technically your just removing the belts and replacing a pulley Link to comment Share on other sites More sharing options...
PeterH Posted May 26, 2012 Report Share Posted May 26, 2012 I've got a brand new tensioner i've found that you can have for £40 It's an INA but doesn't come with the pully... Link to comment Share on other sites More sharing options...

sebgreen Posted May 28, 2012 Author Report Share Posted May 28, 2012 Just realised mine is hydraulic and not mechanical! Damn Does anyone know the torque for the actual tensioner wheel onto the rest of the tensioner unit? Its a M10X25 Bolt Link to comment Share on other sites More sharing options...
sebgreen Posted May 30, 2012 Author Report Share Posted May 30, 2012 Did this job today. Both tensioners replaced. Aux belt was hydralic and the piston was ok so just replaced the pulley wheel, mudguard and bolt. Replaced the Idler pulley also as it had no resistance when span and was loud. Replaced entire mechanical A/C belt tensioner. Both belts. Easy job - took half an hour, if that. Link to comment Share on other sites More sharing options...
