My 3L P2 GTV is due for a cambelt change, and I'm trying to figure out if it's a job I can do. I don't mind spending a bit of time sorting it out and I enjoy tinkering, but then I also don't want to wreck the car. I've done a belt on a Golf and and 106 before, but looking at all of the guides the Alfa V6 looks somewhat more involved.
The car is coming up to 100,000 miles and the engine was rebuilt at 60,000 miles. I'm not sure exactly what work was carried out at the 60,000 mile rebuild.
First off what parts must / should / sensible be replaced on the way?
- Cambelt (before I forget to order the obvious)
- Auxiliary belt
- Auxiliary tensioner
- Auxiliary idlers?
- Water pump - I've no idea if I have the plastic impeller or not
- Sealant for water pump (blue Hylomar) - I've read it can weep
- Any certain size bolts I'm likely to need to replace?
- Anything else?
What specialist tools?
- 41mm socket for crank shaft nut, with OD no greater than 55.6mm
- Goose neck spanners (15mm) for
- Cam locks
- Longer bolts for the cam locks (M8 x 1.25 x 50mm on 30mm deep camlocks)
- TDC holder
- TDC guage
- Tool to rotate pulleys - or can I use a 24mm spanner on the shaft?
- V6 Cambelt Tensioner Adjustment Tool - is this required?
- Locking pin - required?
- Pulley puller - Presumably required to avoid needing to use crow bar to remove pulleys
- Crankshaft Pulley locking tool - Will I need a windy gun to loosen the crankshaft nut if I have this locking tool. Also is this the correct size?
In terms of finding TDC accurately I've read on the 156 forum
that the gauge is not a good way to do it. Is that hogwash?
From what I've read the tricky part seems to be loosening the crankshaft nut and removing the pulleys. I'm guessing with the crankshaft pulley locking tool and pulley remover this is simple.
In terms of lining everything up the cams seem straight forward with the cam locks.
That just leaves getting TDC. I'm confused where this guide
Refit the crankshaft pulley without the pulley and use it to rotate the engine
Do I need to pull off the timing belt crankshaft pulley, or is it sufficient just having the cam shaft pulleys loose to get equal tension? Am I meant to replace the nut and and use this to turn the engine - if so what was the point of removing the nut? Could someone elaborate on this?
That's a lot of questions. I just want to feel comfortable I understand everything before embarking on this!
