Most garages charge around £40ish + to re-gas the aircon.. try some industrial air con places, a place near me does it for £20 cash in hand
Coolent will be about £25 ish
PAS fluid
Possibly brake fluid?
then your oil and filter..
so thats over £100 there, with good oil
Not quite the same but my on my old MK1 RSi it took 7hrs with a ramp...
In that time me and my dad drained all fluids, removed the engine, fitted new clutch, gave engine a quick inspection/clean while out, refitted the engine, also fitted 2 new engine mounts and all new the filters/fluids.
Done!
