Hi All, not been on here for a while as my CDTi Tourer (2007) has been behaving very well of late - until now...

Battery warning light on - have used testers to check battery and it appears that the alternator has packed in.

Battery is at 12.3v when engine off and much the same when engine on. This figure goes down if I put all lights on to around 11ishv

Battery is 6 months old premium quality

It looks like the belt change/ re-route has never been done on this car, which is at 115k

The alternator/engine noise is more whiney than before, so given the above, I think it is safe to say the alternator has had it.

OR - are there any other checks i can makes somewhere? Fuses? etc?

I am near Witney, Oxforshire. I should be able to source a replacement alternator easily enough, however fitting it is probably beyond my expertise....

Can anyone recommend a trusted honda specialist/expert that could do the alternator swap for me & preferably the revised belt too at the same time. Obviously a bad time of year for this to happen but I'm also in a real rush to get the car back on the road...

All the best, Tom
 
Further to the above - which might help in confirming the problem, yesterday, I was getting a message on the screen saying that I must start the engine before using the air conditioning (or words to that effect), although the engine was running and the A/C was off...

also - any pointers to sourcing a genuine Denso Alternator in a hurry would be appreciated as I'm struggling to find one available right now, what with it being a bank holiday...
 
You won't get a genuine one today but Eurocaparts have them for under £200 after using promo code Xmas.

Genuine one will cost a pretty penny I imagine.
 
Cheers Salim - You're a gent! Just been onto EuroCarparts and found they do the Denso Alternator which is very pricey BUT with the xmas discount code, they knock off £130 making it £260, which is still pricey but I think I'd rather have the Denso OEM brand. I've reserved one to collect first thing tomorrow & will have a crack at fitting it myself using the DIY guide on here (written by your good self!)

Now, any chance you could also make life even easier and move to my village & fit it for me...??!
 
That's not a bad price for a Denso(without looking)

Oh yes that diy was a while ago. iirc get the correct off set spanner, long enough or a tube to go over for additional leverage. I put the alternator on with the belt partially attached which is not the best way. So bolt the alternator on and then slip the belt over with the tensioner held back.

Would be happy to give you a hand if you was closer.
 
Now, thinking ahead to tomorrow's challenge of changing the alternator, I think it'd be a good idea to change the belt for the revised shorter one..

I'll see if I can find that at ECParts, otherwise I'll call into the Honda dealership after I have picked up the alternator.

Can anyone advise what else I should look at replacing whilst I'm in there? Tensioner pulley? etc?

Many thanks, Tom
 
Thats a great price on an alternator.
I was in a similar situation to you, mine just gave up although I knew it was going i pushed it right to the end. lol
Managed to get a genuine Honda one for £320 in the end. Pricey but no one had any refurbed ones in stock and ECP didnt have any decent branded units in stock either.
Cant go wrong with genuine - lol

Definitely to the shorter belt modification. You will just end up damaging the alternator again.
I didnt change anything else. Once you remove the belt you can examine the pulleys and idlers and see if they need replacement. Most likely they should be ok.

Short belt part number is: 04301-RBD-305

Doing it yourself isnt too bad but most likely you will round the tensioner pulley bolt. If that is the case you will have to do it the old fashion way and use a crow bar of some sort and lift the tensioner away manually.


Your not too far away from:
Performance Autoworks
http://www.performance-autoworks.co.uk/index.php

A guy called Rich runs the workshop there and is a Honda specialist.

He has worked on all my Honda's - major work in which I can't do and is extremely knowledgeable with everything Honda.

He did the alternator and belt re-route a couple years ago for me on my icdti accord. (I just didnt have an aux belt tensioner lever or anything long) so i got him to replace it for me.
He has done a host of work on my 1999 prelude when i had it. Including final drive and LSD upgrade and auto to manual tensioner conversion for the H22. All work was spot on.
He has also done a rear brake disc conversion for my brother EJ2 civic coupe.

Fantastic guy and well trusted place.
Hes around half hour away from you if you get stuck.

Ask for Rich and say Alex with a Black Honda Accord recommended you.
He will sort you out.

Hope it helps if you run into issues trying it yourself.

He responds extremely well to emails if you prefer that type communications.
 
Thanks for that, not too far from me and comforting to know there's a good indie not too far away. I managed to drive 30 (nervous) miles with no alternator today and have since had the battery on charge. I'll give it a crack tomorrow myself knowing professional help is within reach!

For the revised (shorter belt) eurocarparts brings up this:

Looking at the label on their pic, it's a 1784mm long belt, whereas Honda spec is 1785mm? ***ume an extra 1mm isn't going to be a problem?

All the best, Tom
 
Another quick question, as I'll be starting on this later this morning...

If I am replacing the belt with the shorter revised version, can anyone see any harm in me starting by simply cutting the old belt off with snips? Then removing the idler pulley, giving a bit more hand room for the alternator removal?

Cheers, Tom
 
EUROCARPARTS - not much use (SWINDON Branch)

Picked up alternator this morning and set to it (having got belt from Honda, as despite showing as in stock, ECP didn't have it)

Got everything stripped down, got old Alt out and lo and behold, ECP supplied the wrong alternator (but in the right box). Phone them up and they say no problem, we will send correct alternator out with our driver, you will be the first drop off and you'll have it by 2.40pm. 4pm comes and they arrive, hadn't told the driver to drop to me first, now too dark to complete job!

Only got the belt to loop over the top pulley with homemade tool (ground down 14mm socket welded to flat bar) the wiring to reconnect and the undertray to sort.
 
Whoop Whoop touch wood all sorted apart from reattaching the under tray, just come in to warm up with a coffee first.

Many thanks to all, especially to those who have provided very informative diy guides on here. The job isn't too hard, more fiddly really. Few tips I can give...

1. When removing/refitting alternator, as well as radiator shroud & coolant tank removal, it is helpful to undo the air conditioning pipe clip (front left corner of engine bay) this allows the pipe to be encouraged gently further out of the way.

2. Entire job can be done with car on ground, wheels on. For rerouting the new belt, just a little patience and a length of dowel will get it over the lower pulleys.

3. If using a ground down 14mm socket welded to some flat bar steel to lever the tensioner, when refitting the belt, 14mm x 3mm is not strong enough and will bend. I ended up welding two lengths of this steel together.
 
Good result, thanks for the tips. Having a welder is a godsend.

A job well done ✔
