Hey guys just bought my first holden the other day and its a beauty, 2000 olympic iii vs spac commodore ute. its a 5speed manual and has only done 90,000klms! needs the cooling system overhauled. got quoted $1000 to get radiator, all pipes and clamps, thermo stat, manifold gaskits with o rings, heater valve and pipes, plus all clamps plus a pressured flush then coolant replaced. is this a reasonable price. plus is there anything else i should consider maybe water pump?
