Andy,
Are you sure you are talking about the alternator belt where is it on the engine?
Assuming it is, are the other belts in line? If not could be the crankshft pulley coming off! If in line then the alternator may have been replaced with the wrong type.
Crankshaft pulley covered on AceAnswers. Someone may have the Toyota part nos for alternator(s) to hand but you would need to get it off to see!
TownAce Nutters Site give a garage near Sittingbourne/Faversham that may help you.

hi clive

my townee asc has 3 belt 1 for the ac 1 for the power steering and 1 for the alternator/w.pump
it now looks like it the pully on the water pump at is out off line with the alternator pully and the crack

Andy,
I can't recall if you can fit the pulley behind the fan on the wrong way round, but if crank and alternator line up then that is a possibility. Only four bolts behind the viscous fan coupling and that would be an easy cure.
It's not the water pump pulley, that is driven off of the timing belt.

hi clive

yes iv been to the loco friendly car shop and we looked tho all the book to see if it was poss to have been the wrong pump but no it the right pump so next when it stopped raining il remove the fan and then the pully to see what been happoning with it

iv look on the web site but only ref to Sittingbourne/Faversham and thats rads repairs??

- (#7155) andy in kent, 11 Feb 03

Yes Andy, you can remove the A/c belt, but then why buy such a well specified vehicle, then remove some of it's best features. Additionally you'll find that if you don't run the A/C at least for a few minutes a week, the seals will crack & shrink & thus lose the gas, let in moisture which will corrode the internal working parts & eventually leave you with no A/C at all & hefty repair bills for it. HTH Rob.

HI ROB

Obviously you have the floor pan out and you can see that the belts are not in line !
Having had all my belts and pulleys off my 2ct engine, I don't believe you could fit any of them backwards.
Do all the pulley slots have belts on? Is it possible someone has fitted an alternator with a single belt when the vehicle originally had a double belt. They would of had to of fitted a waterpump / fan pulley and crankshaft pulley with a single belt as well.( Possibly as a result of having to replace one pulley they replaced all due to cost ) Is this possible? and the combination does'nt line up.
You don't say, if either the waterpump or alternator have double pulley V's. I know this sounds stupid but you don't make that clear.
Others with more knowledge than I may be able to advise you if you can convert a double pulley system to a single one.
You note that you have recently acquired the vehicle !
Any chance of talking to the previous owner or dealer about it?
Check your log book and be cheeky! Phone the previous owner and enquire about it.
If anyone could provide photo's to Andy of their pulley alignment it might help!
Also, If you have a mix of a 3 and 4 belt system, and I know this is stupid again, but are all the right belts on the right pulleys. Never having measured them I don't know if you can make a mistake but in my 2ct all are v belts except the Air con. Could you drive the steering pump off the alternator? I don't know. If you have a 3 belt system ( mine is 4 ) I assume, 1 belt crankshaft to steering pump, 1 belt crankshaft to Air con and 1 belt Crank to waterpump to alternator.
I hope this give you and others some ideas.
Good luck resolving your problem

If you go to the following URL, http://www.myrtleave.freeserve.co.uk/towniepics.htm
you will see that the fan belt system is shoen in detail in one of the pics on my site, the top pulley is NOT the water pump, the water pump is driven by the timing belt. I should think that the vehicle either has the wrong alternator on it, or that it has been fitted on it's brackets incorrectly, without a photo of the underbonnet view it's very difficult to say what the trouble is. Do you have a digi camera so you can post some shots on here for diagnosis reasons. ROB.

Your quite correct. While many refer to the viscous fan and pulley as the water pump,( myself included ) it is not. I afraid thats a terminology, to easily, carried over from working on many engines where the water pump and cooling fan are connected.

Just in case these pics help and you haven't found them ... in the Ace Answers Engine mechanical folder see (3) "Engine (2C-T) driver's side, front view and normal access" and (2) "Engine, stripped RH & LH".
The clarity of these pictures is compromised for speed of download but I can probably increase the definition of the published version if you say which is of interest.

i have a 3 belt system , 1 belt crankshaft to steering pump, 1 belt crankshaft to Air con and 1 belt Crank to waterpump/fan(but dus not run w.pump) to alternator.
steering pump and A/C are ok only the v/fan pully is out off a line ment i will today take some pic and post em off to u

sure the pulley isn't on back to front?

- (#7243) david miller, 14 Feb 03

no the pully is not back to frunt

- (#7244) andy in kent, 14 Feb 03

The pulley that runs crank/fan/alternator should be a double belt I.E. two belts side by side of exactly the same length, as per my website picture, if your set up has only 1 belt, I suspect it is the wrong alternator, now that's also a problem as it carries the vac pump piggy back on it.

- (#7245) Rob Drinkwater, 14 Feb 03

not necessarily, Rob. pre 8/90 townies only have one belt to the alt & fan

- (#7246) david miller, 14 Feb 03

The pulley that runs crank/fan/alternator is only 1 belt, and still carries the vac pump piggy back on it.
so far iv had the pully removed and pressed 7mm to make it fit in line better so far going ok but not fixed

Sorry David, just looked at my records & see the earlier models have only 1 belt.Rob.
