Hi,

I have just bought a Fiat Marea Weekend TD100 ELX, I'm its third owner. It shows 59,500 miles on the clock and from reading elsewhere I get the impression that it would be a good idea for me to change the cambelt sooner rather than later, especially as it came with no service history and we are planning continental holiday in it (to Italy).

Haynes don't do a manual for tha car at all but I have managed to pick one up from Porter. At first glance it doesn't seem as comprehensive as the Haynes manuals, but that may just be because I am more used to their style.

Anyway, it does imply that I need a special Fiat tool 1860905000 to hold the crankshaft at TDC while I change the belt. Obviously I don't have such a tool but it looks like something that I could easily knock-up from a piece of scrap metal if I did but know the exact dimensions for it, specifically the distances between the various holes.

Does anybody know of a drawing of such a tool, with Dimensions shown, so that I can do this?

Alternatively does anybody know of any instructions for alternative ways to do the job on a TD100 engine.

Thanks in anticipation (and please be gentle with me as I am new to both Fiats and this forum...).
 
The main purpose of the tool is for setting up the fuel pump timing.

You can get away without the tool as long as you mark the crank position before removing the old belt and don't slacken off the fuel pump pulley. I always put my own paint pen marks on the crank, fuel pump and any balance shafts so I know their exact positions before the belt is removed and just make sure they're back in the same position with the new belt.

I've used this method on a 1.8 Ford diesel and 2.0 Freelander diesel before without any issue.

Thanks. I have taken a look on eBay and there isn't one available at present. I could wait but I was hoping to get the job done somewhat sooner than simply driving around waiting for the old belt to snap, if you follow?

This had occured to me as being a possible route, and is probably what I will do if nothing else surfaces as a method, although as the tool looks so painfully simple to make (little more than a piece of flat bar with a couple of carefully placed holes drilled in it) I was hoping that somebody would know the necessary dimensions.
 
Related question: I have also heard that it is advisable to change the automatic cambelt tensioner at the same time as the cambelt. Is this true?

Not advisable, I'd say imperitive. When the cambelts have gone on most Bravo/as and Mareas it's the tensioner that has gone rather than the belt itself.

Are we just talking the automatic tensioner here (the component that can obviously fail) or the idler gear too?

Sorry, don't know to that detail. Best advice I can give you is to give Rog at www.powerfiat.co.uk a call. Absolute star of a bloke and will give you all the advice you need.

I only know about the tensioner and believe there are 2 that have to be changed (this may be the idler you are concerned about).

Basically, there are so many horror stories about cambelt related failures with Bravos that I would get everything that the belts are connected to (within reason) replaced as part of the work. More often than not it is not the belt that fails but something it is connected to that makes it either jump or shred.
 
Thanks for the advice.

I have phoned Rog at PowerFiat as you suggested and he was very helpful; gave lots more sound advice, including to replace belt, tensioner and idler and to check water pump bearings (but not assume its in need of replacement) - i.e. exactly as you yourself advised. His prices are so reasonable that I'd happily let him do the job... were it not for the fact that he's now booked up until July :-(

Rog also suggested that I phone Steve at Alternative Autos http://www.mortloan.co.uk/coupe/contact.htm and ask him to quote for supplying parts (and so avoid Fiat markup) and I am now waiting a call back from him with prices. Luckily I haven't bought anything from the Fiat main-dealer yet.

The first sentance there explains the second one. Rog's reputation is developing by the day and as such he's very busy. Coop owners swear by his work (not "at it" like you do with Fiat dealers) and I, as well as many BOO members, take my car to him as well

Glad you're sorted guy. Good luck! :).

We're not there yet (still waiting for Steve from Alternative Autos to come back with parts list and prices) but things are definitiely going the right way. Thanks for all your help.
 
Hi!

Laser Tools do a kit for these engines & it also covers Pugshot/Citroen XUD including Turbo diesels!!!

Find a Laser Tools stockist and ask about Engine Timing Set no 3471 - I got mine for £34 approx but a good Laser Tools or Sealey Distributor should be able to get you a 3471 kit or its Sealey equivalent!!!

Its not particularly difficult as there's fairly good access between the pulleys and inner wing, & you also need a Ribe Set (Halfords or Sealey) for the crankshaft pulley - note on these engines it is ***not*** necessary to remove the large central bolt!!!

Hope this helps in the future - this is quite an old post so I'm assuming you've had it done by now!!!
