New berlingo owner

[VFR750BERLINGO]

Hi all.....

From Aberdeen and I'm very very new to the van scene......first one.....04 1.9D Berlingo! roof rack, cage bulkhead and rear mat liner, its had a hard life but nothing I cant sort out. I've had a fair mix and match of cars over the years. Renault Clio, Civic Type R ep3, Toyota Hilux monster truck, BMW M3, Pajero, Audi RS4, Discovery 2 TD5, 4.4l V8 Range Rover and now my wee van.

1st thing on the cards a service....book says 76k miles it was last done its currently on 122k miles but the previous owner to me said it had been done before he bought it he only had it a year

2nd thing is the timing belt again previous owner to me said it was done before he got it.......one more thing.....is there any how to guides for this timing belt?!?!?!?

I have no owners handbook either, what's everyone's preference on engine oil 5w/30 or 5w/40?

Thanks all
