  • Engine noise (Alternator)

    Hi all

    I have this metal on metal noise (whine) emanating from the front of the engine and seems to originate from the alternator. About August last year I did a salt water crossing and am wondering if anyone agrees that salt water from this might have got into the alternator and done some damage or has experienced anything similar?

    I went to Toyota today, $717 for new alternator not fitted :shock: and they don't do recon one's for my model :evil: My last option is to take it to Toyota for them to remove and get an auto electrician to recon and fit back in.

    I'm starting to regret the salt water crossing, what is the general consensus on them in PP land?

    I ran a 4wd course for some fellas down at Esperance and they couldn't help themselves and ended up at a local salt lake to play in the mud. The mud got into everything and took hours to clean off. One of the vehicles, a Holden Rodeo, had to visit the dealer where the alternator was replaced due to "Excessive Mud Ingress".

    The salt shouldn't really affect anything as long as you get at it with a good hosing before it has time to bake on.

      Sounds very prabable to me mate. The Prados do suffer from water damage to the starter/alternator. Do some searching on the forum and you will find plenty of others in similar situations.

      My next move would be to take it direct to an auto electrician. They will not charge anywhere near as much as Toyota for labour. You will also avoid Toyota's "mark up" for the alternator overhaul.

      Get some prices 1st though cos I just checked ebay and you can pick up a brand new alternator for $250-$300.

      Good luck.

            Hi robbo79
            Also located at the front of the engine and driven by the same belt as the alternator is the belt tension idler pulley.
            These idlers run with unsealed bearings and can have a tendency to dry out and squeal like the proverbial even fail after dirty water crossings etc.
            These bearings can be replaced with the addition of a machined bush as Toyota has patented the size of bearing.
            Some Pradopointers have posted on their experiences.viewtopic.php?f=14&t=760&start=0&st=0&sk=t&sd=a&hi lit=pulley+bearing
            Good luck
