Hi, im planning on buying a 1992 sc300 and ive been searching for about 2 hours now and haven't been able to find a solid answer to this question. After buying the SC300 whats the most important things i should replace first?

I noted some things from past posts like but idk if they were accurate or not.

Timing Belt + Water Pump

OIL CHANGE + Good Oil Filter

Air Filter/Fuel filter and PCV Valve

Transmission Fluid

Brake Fluid

Radiator Fluid

Fan clutch

windshield cleaner/wiper

Brake pads

 

You didn't find an answer because there is no answer. It depends entirely on the vehicle and what maintenance has or hasn't been done. Prioritize your list once you know what it needs.

 

That list is a good start. But like what t2d2 says, it all depends on what the history of the car is like, and what else is wrong with it.

Here's everything I would change if I got a car that I knew nothing of it's history


Timing Belt, Water Pump, Thermostat, T-belt tensioner, T-belt idler pulley, new harmonic balancer, new crankshaft bolt, Toyota coolant

Synthetic oil and a good oil filter.

Air filter, cabin filter, fuel filter, PCV valve

Distributor cap & rotor, spark plug wires, spark plugs

Trans fluid and Diff fluid

If you have any noticeable oil leaks coming from any seals, replace them ASAP before things get worse. Front seals do at the same time you do the T-belt service
Normal seals that leak with age: Camshaft seals, front main seal, rear main seal, valve cover gaskets

Replace wipers if they are old.
Replace brake pads if they are low, or you don't like how it brakes. Do a brake flush at this time
Replace/upgrade any burned out lightbulbs

 

thanks that makes more sense.
