Hi Sheppy, It it engine or road speed related? Does it change when you dip the clutch? Does it change when switching from drive to overrun?

sheppy Posted March 4, 2008 Author Share Posted March 4, 2008 the sound doesnt appear to change when the clutch is depressed.it sounds like the same wirring noise the belts located on the front of the engine below the cooling fan. i noticed that these make a noticable amount of noise when staionary/idle. could it be they need tightening/replacing?? Thanks Quote Link to comment Share on other sites More sharing options...
Gromit Posted March 4, 2008 Share Posted March 4, 2008 I assume you don't have PAS fitted? though you say belts Could be bearings in the water pump or the alternator. You can remove the belt round the water pump and alternator and run it and see if the noise is still there. Don't run it for longer than a few seconds as you'll have no coolant circulation without the pump running. If you do have PAS, do the same and remove the belt and see if the noise is still there. To locate the noise, if you have a length of hose, put one end to your ear and listen around the engine with the other end. I don't need to tell you not to get the hose caught in the whirling belts Quote Link to comment Share on other sites More sharing options...

Gromit Posted March 4, 2008 Share Posted March 4, 2008 yes it does have PAS, is that uncommon for this age/spec?? Best wait for an adult to answer that one. I can't remember exactly when PAS was introduced TBH, thought it might have been after the TD, possibly not. Quote Link to comment Share on other sites More sharing options...
western Posted March 4, 2008 Share Posted March 4, 2008 Not uncommon on a TD engined vehicle, it's a heavy engine & PAS was a standard fit to them. Quote Link to comment Share on other sites More sharing options...

Guest wunntenn Posted March 5, 2008 Share Posted March 5, 2008 Check your speedo cable into the dash - it can make all kind of noises like that if starts to come loose, and it will sound exactly like there's a bit of mischief afoot in the engine bay. Pull the dash front apart and check that its properly screwed in. Does your speedo needle dance about a bit? Just a thought. Quote Link to comment Share on other sites More sharing options...

If the noise happens when stationary, it won't be your speedo, as it doesn't turn while stationary! Quote Link to comment Share on other sites More sharing options...
