Although I don't have much experience working on vans, I recently started helping my neighbour, who runs a man-with-a-van moving business.
2005 Iveco Daily box van 2.3
Tightened suspension mount bolts.
I helped him remove the air bubble from his coolant reservoir.
Replaced his leaking radiator; after replacing it, I did the same as above.
Future Work:
I have also been asked to help with upcoming oil changes and diff fluid changes. I've also been asked to help with any other work that may be needed.
