Tensioner snapping off the mount TDV6
	
	
		Was it the first or second belt change? If first it was well and truly overdue so you obviously knew this needed doing ASAP? Assume you negotiated the belt change in the price?
Did you buy privately or was work done via the selling car yard? Was the workshop LR experienced?
Anyone you can go back and have a chat with or push on their or your insurance on basis that excessively torquing up the tensioner led to the failure i.e. it was perfectly ok up till then. That’d be my angle with said repair shop. Worth a crack.
	 
	
	
	
		Re Tensioner snapping off
	
	
		Had new serpentine belt and tensioner fitted at same time engine timing belt done.
1500K's later driving and thought the cross wind must have been strong as steering got heavy....then temp went up.
Found that head had come off the tensioner for the serpentine belt, all belt functions stopped.
Seems enthusiastic mechanic may have either not fitted new bolt with tensioner, OR overtightened bolt, partly breaking head, which later dropped off.
Found the bolt head on the tray under motor when I went to change oil next and it looked like it had been half torn off when being tightend. (overtightened)
SO new bolts always with any new tensioner and make sure not over tightened.
Sad to hear about cost of new motor. 
Good Ford Territory 2.7 motor can be had for under $6k and also fits (same engine, change front pulleys and sump).

184,000 on clock when purchased, we changed belt then. Fast forward 40,000k's later. Was done in Gold Coast. Here are some photos
Paid $19k and apparently $17k to get another LR motor.  PS I am a newbie and so forgive me lack of understanding.
 Gutted. I live in South Coast NSW.

		Service period for changing belts and tensioners
	
	
		I have been lucky so far with any "failures', but I have always changed my engine and fuel pump drive belts and tensioners at 160K or a bit sooner if I am near a service option.
Last front engine belts and tensioners done at 120k and noted that the old tensioner appeared loose to turn, so not sure what that would have been like if I was waiting until the 160k.
Have had tensioners for serpentine belts get noisy and need changing after only 40,000k.
Possible that manufacturers (LR UK) are aware that optimum life of tensioners and belts may not 160k, but to suggest more frequent chnages may increase listed running costs and make them look more high maitenance than their competitors, so they gamble with the chance that only some will fail if they suggest and extended change period.
EG: The same reason that transmissions are marketed as "sealed for life", which greatly reduces the listed running costs of the vehicle and possibly makes it more attractive to the naive purchaser (who belives that transmissions are indeed perpetual motion units).
