Replacing Td5 drive belt

Maybe someone has fitted a smaller idler pulley.
Mine has no ACE so is 1801 AFAIR.

1870 is both AC and ACE

I have read 1801 and 1802 for AC only but I think they just make them easier to fit and the tensioner has enough uptake to allow for the extra length.

A 10mm ring spanner to remove one of the bolts behind the fan allows access for a shifter, usually a hit on the end of the shifter with the palm of your hand (normal RH thread ie; undo to the left when viewed from above) is sufficient enough to loosen it, if not a quick tap with a hammer. :D

But, the reason I looked up this thread was to find the length of the serpentine belt. 1870 is listed for a TD5 with ACE etc, mine is an 1870 but there is NO tension left, the tensioner is hard up against it's stop. :confused:

The problem is it sounds like a banshee when starting, the belt slip is horrendous. :eek:

Anyone else ever come across this before? :confused:

Cheers

Be careful giving it a tap with a hammer, it can transfer a shock to the fan hub bearing and cause damage.

Re: belt is too tight, is there any chance the belt is undersized (can you remove and compare with the old belt)?

Re: screaming belt, I had the same problem after installing an after market idler tensioner. Instantly fixed by fitting an original tensioner.

At this point may I make a suggestion, when you remove the belt, check all bearings in the drive train, by hand. Idler bearings can be removed, the plastic carefully removed, & new bearing greased applied. You may be surprised at the lack of grease in them. I do this every oil change, I think if I waited for 100,000 KM's to take the belt off, I would have forgotten how to do it. Check the viscous fan bearing at the same time, doesn't hurt. Bob

Does any one have a map of where the belt goes? With and without ACE.

Td5 Drive Belt With AC With ACE

Non ACE is the same.

Thanks revy, that's going to make life so much easier, when I finally get a belt, which looks like next week.

For everyone's information, 7PK1870 is a common belt used across many Toyota models.
If you were remote, a Toyota dealer should be able to help you out. [bigwhistle]

Good pickup. I'm due for a new one.

As for spanners, I borrowed a good pair from our good and sadly departed mate, Mario. I believe he had them made. There was one for the fan nut and another that fitted over the small bolts on the pulley.they were really handy, as mu fan hub was actually rusted on sorta. Bloody tight anyway. Actually, come to think of it, that would have been off when the HG was done two months after I bought the car so maybe the shop used thread lock, but I can't see why as engine DOR would self tighten the hub.
