Alternator through bolt

Hi all. Can someone cast some light on this issue -I want to change the drive belts and was hoping to do it myself rather than take it into the garage.

The alternator through bolt at the bottom of the unit just won't loosen off. The service manual says to loosen it from the drive-belt side, on my Bongo the nut is actually on the left side of the through-bolt (next to the oil dipstick). Should I loosen the nut end or persist with the belt side as per the service manual?

Having removed mine today to change my water pump I would say undo the nut next to the dipstick.
'Coz that's what I did.

Cheers Tony - I found that even when taking the retaining nut off the dipstick and moving it to the side I couldn't get a socket on it. I tried a 14 spanner but couldn't get the nut moving what did you use?

Mine was tighter than a tight thing too!
What sort of spanners do you have?
The way I did it was using combination spanners, place the 14mm ring on the offending nut and this will leave the open ended part stuck up in the air. Then get a bigger sized combination spanner (I used 18mm) and place the ring part over one of the jaws of the 14mm and use the extra torque available to crack the nut.
I hope you understand this concept. If not let me know and I will post a picture as it is worth a thousand words.

=D> I read this and thought 'I've gotta get me some of those combination spanners! Checked out a picture on Amazon I realised I already had them #-o Still couldn't quite figure out the linking bit so got the spanner and hey presto it works - brilliant tip!!!!! Thanks.

ps. real mechanic me can't you tell 8)

Not a problem!
At least I learned something fixing submarines for 20 years :)

Submarines? I'm assuming today's water pump change went well then :) Did you also do the thermostat, as I've read most people on here seem to change them together?

Yes!
I changed the water pump, stat and fitted a temperature sensor pocket into the radiator top hose so I can have a digital readout.

Hi folks... from memory when I did this I used a three foot long 3/8 inch 'breaker bar' and a regular 14mm socket... the leverage on the bar is huge [works well on wheel nuts and head bolts - NEVER use your torque wrench for 'undoing' as the force can damage the tool] When the breaker bar is pointed vertically down onto the bolt - from the centre of where the gear change normally would sit [and you're standing in the front passenger doorway] you can exert the force you require. The breaker bar's 'universal joint' knuckle enable it to offset about 5-10 degrees from the vertical towards the rear of the van to allow it to miss fouling on the engine bulkhead below the heater controls/radio etc... Hope this is what you were asking about anyway?!?! [it was a eureka moment for me]..

Mac.

Most of the bongo bolts I've undone using that sort of leverage have simply sheared. That might do the trick though!

Hi
It's often not sheer force that's necessary, but a wallop on the spanner with a hide mallet, or heavy rubber hammer....NEVER hit a spanner with a metal hammer!
