Bahahar yes all true, but it involves advanced tasks yeah?
Take off belt, dunno how, take off a heap of wheels, maybe not too hard, but then id hav to drain the coolant yeah, then probably hav to depressurize something the twinkle some control unit the whatever whatever
Dismatling things off the block is advanced mechanics, u blokes are all wizards dont pick on the students, my dear great & masterful genius's
Sorry we didn't realise you were a gen Y and can't pick up a spanner or read a repair manual (not taking the piss). Probably best to park the car and catch the bus while you save up for professional assistance.
Correct sealant is prolly closer to $20 and if you shop around for a pump, $70ish, throw in concentrated coolant, $20 and I think you be way in front and learnt how easy some things are to do with basic tools.
Each to their own.
