Why these three
Renew cooling and lubrication in one job
Water pump
Moves coolant between the block and the radiator. A leaking seal or a worn bearing can overheat the engine quickly.
Thermostat
Brings the engine up to working temperature fast and keeps it there. Stuck open, it raises fuel use. Stuck closed, it raises the risk of overheating.
Oil pump
Feeds pressurised oil to the bearings, camshaft and turbo. Skip it in an overhaul and the new bearings run on the old pump's pressure.
In an overhaul or major service, these three parts usually end up on the same job sheet. Replacing them together means less chance of opening the engine again soon after.
