Default Volvo 940 stage 0, what's needed?

Just like the title says, what is most likely needed to make the engine run like it came from the factory?

Probably check owners manual, set everything to specs, make sure no leaks at all, replace fluids everywhere.

Disregard turbo stuff if you don't have a turbo.

Change the oil and flush the coolant
Inspect the hoses and belts
Check the tire pressure and make sure that nothing is about to fall off of the car


Assuming that the car runs, you can start on the list below:

-Remove and clean the positive crankcase ventilation breather and associated hoses.
- this may require removal of the intake manifold, but that is okay. Your car probably needs a new intake gasket anyway


Oil leaks should be fixed first.

Valve cover gasket/ half moon seal
Oil cap seal
Turbo return line o-ring
Turbo return and feed gaskets
Distributor o-ring (740/ 940)
Front/ Rear engine seals (AKA crank/ cam/ aux shaft and rear-main)
Oil pan gasket


Next:

Inspect wiring harness for damaged wires - Extremely common problem in ALL Volvos built before 93!!! The wires degrade when exposed to oil and long periods of heat
240 models only - clean fuseblock and replace fuses
740 models only - remove foam insert in airbox
740 models only - inspect (or remove) preheat bypass valve - this will cause multiple AMM failures if not replaced when faulty!
Change timing belt and accessory belts
Check base timing
Flush coolant (if not done before)
Inspect hoses/ waterpump
Replace spark plugs
Inspect cap, rotor and wires
Replace air filter
Replace thermostat
Change heater hoses
Replace heater valve (740/ 940?)
Flush transmission fluid (auto and manual)
Adjust kickdown cable (automatics)
Adjust clutch cable (manual transmission)
Check all suspension bolts/ bushings
Inspect brake hardware and pads/ rotors
Flush brake fluid
Replace fuel filter (main and in-tank - replace fuel line in tank as needed)
Inspect transmission/ rear-end for leaks
Replace rear-end fluid
Inspect/ replace vaccum lines
replace check valves for CBV and Brake Booster
inspect turbo hoses for softness or tears - look for oil inside hoses, replace as needed


Congratulations! you have just done a 30,000 mile service on your car and it no longer leaks oil!
