    My Garage always recommends this. They renew relatively cheap bits when the bigger job is stripped down. I'm due a cam belt change on my '07 Ducato soon and I'll check the other bits have been done.

    Replaced timing belt on my 07 2.3 last week and was going to do the water pump aswell but garage said on mine it was easy to get at so could be done fairly easily by its self

    the reason why it is reccomended that water pumps are changed along with some cambelts, is that the toothed pulley on the pump forms part of the cambelt set up [along with tensioner wheels and diesel fuel pump sprocket] if you dont change it you run the risk of the water pump center bearing failing due to the tension which the new timing belt puts on it ! if it does, then virtually the whole job has to be done again to replace the failed and[ usually by then] leaking water pump ! like most things in life its a case of is it worth not changing when they can cost as little as £10 trade !!! regards garry

    Incredible as it may seem, your garage was trying to save you money and hassle long term.
    I endorse what greyman says above. My son has a garage and some people want just a cam-belt and wont pay for a tensioner and pulley set.
    And look what can happen to a worn and brittle tensioner. This engine was about to let go, it came in for an MOT and we were drawn to the cam-belt area and saw the broken bit bouncing around !

    if its a ducato your garage was lying to you.

    to change the pump means the same amount of work as changing the belt.

    the pump is driven by the cam belt and it needs to come off to change the pump.

    for an extra 20 minutes work and maybe £30 for a pump its false economy not to swap out the pump at belt change.

    I have an 07 pug 2.2 with a chain, so when does the pump want doing on that, or is it on the fanbelt where they always were and still should be, just haven't looked as I know I should but saw this thread so wondered, thanks

    in general, if a water pump is run via the fan belt [as in a chain drive engine]and therefore does not form part of the cambelt drive, then in theory it should not need replacing unless it becomes faulty or leaks but in reality it is sometimes prudent to replace them if you have to fit a new fan belt or auto tensioner, [for the very same reasons as with the cambelt. it is the retensioning of parts that have gradually settled in and worn together over time that usually causes the problems !!] regards garry

    no need just yet

    recomendation for cambelt change is 5 years or 60,000 miles, whichever
    comes first.
    if the water pump isn't leaking then why change it.

    Read the persuasive arguments above.

    We didn't the first time, next time we will.

    Which I guess, because we haven't had a pump problem, sort of confirms your remark.

    no need to change

    cambelts are scheduled for change every 60,000 miles or every 5 years
    whichever occurs first.
    If the water pump isn't leaking then why change it.
