    Intermittent clicking sound at idle 5.0L V8

    Sounds like I am in good company. Waiting for the replacement idler pulley to come in on Tues. Also looking g at coolant hose replacement as PM. It's about time. NOT looking to do timing chains :)

    Intermittent clicking sound at idle 5.0L V8

    Problem solved. The belt tensioner pulley wheel bearing detonated. New belt tensioner installed. Replacing the smaller idler pulley too as PM. Good thing at 205k km as after I took it off I found it's bearings are rough and noisy (other idler pulley replaced after it detonated last year). Got...

    Intermittent clicking sound at idle 5.0L V8

    Progress.....well sort of. Drove 5 mins to pick up takeout and when I restarted the engine I lost power steering and alternator charging. Limped home and had a look. The 2k km old serpentine belt has come off, so I am guessing either an idler pulley (replaced one 2k km ago) or the ps pump pulley...

    Intermittent clicking sound at idle 5.0L V8

    Guys, Many thanks for your assorted responses. Much appreciated! Obvs been a week or two and weather too crappy to investigate further. In that time did a 600 mile road trip. The engine is now sounding downright 'clattery'. Seems a bit louder on drivers side (LHD). Link to a video below. Any...

    Coolant leak & collapsed top hose when cold?

    I used AC Delco dex-cool compatible dye. Yes, head gasket leak has occurred to me. Checked for white smoke - none. No mayo on oil cap either. Weather crappy at present so no chance to try and ID leak source. Note that the fan does have a slight wobble. Does that sound normal, or water pump going...

    Coolant leak & collapsed top hose when cold?

    Didn't overfill the reservoir. I suspect air in system re. Leak. Coolant has been changed within past 4yrs

    Coolant leak & collapsed top hose when cold?

    Yes, coolant system work done 4yrs ago. I am not so concerned about the extra coolant per se. It's more the erratic behaviour. Yes, opened reservoir cap and the hose remained collapsed. It can't be extra coolant as the level was normal during two days of driving. Seems like a big air bubble in...

    Coolant leak & collapsed top hose when cold?

    2010, V8, 205k km. Water pump and crossover pipes changed at 160k km. Original hoses. So, checked the coolant level last week and it was down to the base of the reservoir. No obvs sign of leaks. Topped it up, drove for 5hrs and no coolant loss. Added UV dye, and have pressure tester to try and...

    Intermittent clicking sound at idle 5.0L V8

    Ah that's a thought. I did read about worn motor mounts and the fan shroud elsewhere. The noise is odd in that it doesn't always have a steady rhythm. If it was mechanical and engine related it would. I will investigate further! Is there an easy way to confirm if the motor mounts are worn? I...

    Intermittent clicking sound at idle 5.0L V8

    My 2010 LR4 V8 205k km has been a paragon of reliability the past little while. Today I noticed a clicking-type noise with the hood open at idle. It's intermittent. Revved engine and it went away temporarily. Link to recording below. Seems to be coming from the top of the engine towards the...

    V8 short drive belt replacement

    Got the new idler pulley from the dealer. Now come in plastic instead of metal :(

    V8 short drive belt replacement

    $25 tool off Amazon worked a charm with the stretch belt. It seated it almost correctly, just had to apply some leverage with a large screwdriver against the outer belt edge while continuing to rotate the pulley to fully seat it. Old belt looked fine.

    V8 short drive belt replacement

    Thanks for the diagram. Longer belt replacement no problem. Its the short belt off the crankshaft I am referring to

    V8 short drive belt replacement

    You have done that on an LR4? The new (LR) belt looks too short, plus would worry about cross threading the bolts?

    '11 LR4 lower contol arm drama...

    Its a pretty clear diagnosis. Going slowly if you pulse the brake pedal you will hear clonking. Mine needed replacing after 50k km or so. There were no other symptoms other than the clonking. Fairly straightforward replacement job, the biggest pain being that a lack of antisieze applied the the...

    V8 short drive belt replacement

    Following on from my 'water pump failure' post below. So the serpentine belt is showing cracks, so am replacing it while replacing the broken idler pulley. I have a new short drive belt, the stretch fit one. I offered it up and it looks woefully short. Before I cut the old one off (looks okay...

    '11 LR4 lower contol arm drama...

    For early LR4's, mine is a 2010 you DO need to drive the axle shafts back to get sufficient clearance. This was a pita on mine requiring an air hammer. Trick is to raise the hub a few inches before driving them inwards

    Does this sound like a failing water pump?

    Found the problem! The RH upper idler pulley bearing is shot. Its totally off centre with just the belt tension holding it on

    Does this sound like a failing water pump?

    So if I remove the fan clutch assembly that still leaves the pulley in place. Is it not the pulley bearings that would be failing?

    Does this sound like a failing water pump?

    But the clutch bearing assembly will still be in place, so will presumably still make the noise?

    Does this sound like a failing water pump?

    Update: I grabbed the plastic fan and wiggled it hard. There does seem to be some wobble, so bad bearings / clutch?
