Hi all,

The vacuum pump on the alternator (91 hilux 2.8D) is dying... The brake light is on almost all the time now and the pedal is getting heavier.

Can I just replace the vacuum pump? If I have to replace the whole thing, roughly how much will it cost and is it possible to install a higher capacity alternator? The current alt is 55amp I am thinking of installing around 90-110amp as I would like faster charging when on camping trips.

Thanks...
Michael

Hi Michael,
my son has same vehicle as you and his alternator died late last year,
I think toyota was asking around $900 but he got one thru local auto elect for $500.
was identical to one we took off which was original AFAIK.

Mike,

I just replaced my alternator with the vacum pump last night (TD27). If I were you I'd replace the whole thing and not just the pump. It wouldn't cost much more and if you already have oil leaking back there, the alternator is not performing 100% anyway.

Hi
There are quite a few alternators available but increasing the Amp capacity does not necessarily give you greater charging as if the overall size is the same then the increased capacity will give inreased heat and restrict the capacity to improve your situation of charging unless you have thermal control of the alternator.

Go for a complete unit for as sure as hell you will replace the pump and then the alternator will die.Bugga.Oh what a feeling.
