Hi guys, i have a 2008 nissan versa 1.6 hr16de and the alternator belt is making an awful noise.

i bought a new belt to change it, as generally i do all my car maintainance myself, but seeing as the alternator is fixed on this engine, how to i release the tension on the belt to remove it?

any help very appreciated guys :D thanks :D

you must LOOSEN the locking bolt on the tensioner pulley. Do not remove this bolt. Just loosen it a little. Then you should have to loosen the tensioner bolt. The locking bolt will be in the middle of the pulley and the tensioner one on the side infront of the engine. I have not done this yet. I am going off of what I seen looking at the car and other cars I have changed belts on where the alternator is fixed.

If you do go ahead with this maybe you could take alot of pics and make a quick howto.

the tensioner pulley is the one with 3 bolts through it then? directly behind the alternator and beside the engine mount?

apologies for the stupidity of that question, but old age is beginning to set in, making modern cars more difficult.

im a member on a few other motoring forums, so i apologise for jumping straight in here with a question, but in exchange, i'l do my best to get a few pictures together for a basic guide :)

Ok I just ran outside to take a look. Tried taking a pic but didn't work. The pulley your referring to is the water pump pulley. Don't play with that. The tensioner pulley or idler pulley as some call it is directly below the alternator. It will be a pulley with just a single bolt in the middle. I also reached under the alternator and I can confirm that is where the tensioner bolt is. The one on the pulley itself locks the position. The one under the alternator that faces the front of the car is what increases and decreases tension.

Man it is going to be simple to replace the belt on the HR16de. I won't mind doing that at all when the time comes.

ok, i understand where you mean now :)

so firstly slightly loosen the bolt in the middle of the tensioner, then loosen the bolt affixing the tensioner to the block slightly and this should leave enough play to remove the belt?

do i have that right?

as we say over here in Ireland 'go raibh maith agat' :D

I do believe that is correct. When a car gets older and everything gets all greased up, sometimes the pulley itself needs a little persuasion to move. I doubt you will have this issue on an 08.

Seems odd you need to replace a belt already on a 2008?


oh and your welcome :). Had to google it though.

BTW I'm going off of a USA spec HR16DE so things might be different but I'm really doubting it.

Fantastic :D like i said, i'l try bash together a bit of a pictorial guide for you tomorrow in exchange.

the car has covered 56,000 kilometers, but the weather the last 2 years being between literally (it was a tough winter) between -20 in the winter to above 25oC in the summer i suppose its just perished the rubber.

i work for a motor spares myself so im no stranger to cars, but its been a good many years since ive been under one, so i appreciate the advice, you'd be surprised how much more intricate newer engines are.

i asume the basic engine and chassis are the same, possibly just spec levels and drivers position differences. and yours probably lives in a more favourable climate :D

Hope you didn't strip the bolt?!!?

Just looked it up in the factory service manual and I am correct about loosening that center locking bolt. Now it doesn't state if it's reverse threaded or not but did you try tightening it. Even if not reverse threaded, sometimes a little tightening can break a bolt free and allow you to loosen it easier.

Rumor has it that nissan uses abnormally large apes to tighten bolts at the factory I hear :). They are a bitch to get off sometimes.

I certainly agree that you need to loosen the locking bolt on the tensioner pulley and the other stuffs are really true. If just in case you might need a new alternator, I suggest you visit car-stuff.

sorry for the offsubject but I have a friend, he's name is abraham, he's hispanic and his parents are from Mexico so I told him hey the Nissan Versa is made in aguascalientes Mexico, he said made in Mexico, built to last! :cheers2: he cracks me up sometimes :smilielol5: anyway,
I know some bolts can be so hard to break, you make the car move pulling and the bolt is still tight. the hardest bolt I had to break loose was a cylinder head bolt from a Mustang V6, it had a head gasket leaking and it took 2 of us pulling with a pry bar, second hardest bolt i had to break was on my Ex cavalierz24, manual said to remove part of the exhaust to get to the water pump, and there was one exhaust bracket bolt, we used the biggest impact air gun they had at the shop and it was still a bitch :banghead: lol
[I'm not a mechanic or anything but back then I worked at a shop getting parts and stuff and taking customers home and picking them up when their cars where done...that was just a summer job HEHE :thumb2: ]
