My GTS-4 needs a new timing belt aswell... only 55,000kms on the clock so i kinda smell a rat too.

I also have been told i need a water pump aswell so thats handy to both at once.

One Question... How much effect would a stuffed timing belt and water pump have on the performance of my car?  

Thanks

your car wont run without a timing belt dude, might run/idel rough with a really worn belt. But its either on or off. Check your belt for gashes/splits and replace if need be.

if you water pump if fuged, your motor is going to run real hot! as water isnt circulating through your radiator & motor. If you cook your motor, your also fuged. Depending how bad you cook it, you could be up for a new motor. (as the motor+ head expandes under pressure, and never returns to orginal state. Leaving your head/motor warped in some areas. This will mean that water is going to get into your oil, diffrent compression readings accross all 6 cylinders. etc.)

Guys,

just for a bit of genral info about the timing belt:

Timing belt controls both camshafts in the RB20,25,26,30

camshafts control valves & valve timing inside the combustion chamber. Valves control the amount of fuel + air entering and exiting the combustion chamber. if the timing belt snaps, the cams & valves stop turning & lifting, but the crank still spins a short time after. This is wear the damage occurs. Ignition is still active, injectors are still fireing fuel into "stuck open valves" & closed valves. This all will stop in a few seconds after the belt breakes. You might be able to buy a new belt, and start it straight away without any problems. Or you may be up for a new head, set of valves, or a couple of pistons. Its just luck! :)

hope this helps.

I think that if they just had to replace a timing belt you got ripped off! ( but then again it is a alfa!) & i dont know how hard they are too change on the alfas!

But if you motor sustained any damage due to the belt and the head had to come off... that price sounds pretty standard.

Cheers,

Timing is timing dude!

all happens in 1/10th of second. Wether its a nissan, dihatsu, or alfa! :P

just make sure you belts ok, and make it a genral rule of thumb when you service your car. (i service my car... as i dont like the idear of 15Y/O, year 9 drop outs, apprenticese's, servicing my car! and i also dont like the idear of the shitty generic oils and belts that nissan use & not to mention my biggest fear........whos car they choose to get the lunches!)

Just a quick tip for the people who are extreamly paranoid, take a photo (with the date printed on the photo) of you odometer. They shouldnt move the car more than 100M...... if they do... ask why? and ask for a complete service report. I have many freinds who work at these places and dont feel completley secure about having a "geniune" nissan or holden service. They all hire apprentices.

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
