Hi,

Let us not forget the timing belt tensioner and the flame trap cleaning.
It’s an important part of the crankcase breathing system.
You might get premature oil seal leakage, of which, helps eat up timing belts.

These are routinely done with tick marks coinciding in-line with oil changes.
Next thing is how often are oil changes, when Volvo went to 7,500 mile intervals in the mid eighties.

3,000 mile intervals are too often with today’s oils unless, you let it sit for years, to get a measly 3,000 miles.

Even coolants go five years or a 100 - 150,000 miles and matchup to water pump replacements.
So two timing belts and one water pump, maybe some oil seals on the side!

Jeez, I’m starting to sound like a menu in a restaurant!
Tips anyone?

I repack my front wheel bearings and check valve clearances every 50k miles. I also replace my spark plugs every 30k miles.

For me, "routine" maintenance includes regular changes of ALL fluids. Transmission, rearend, power steering, brake fluid and coolant I'd add to your list. For my daily drivers - I do tranny, rearend and power steering every third year. Brake fluid and coolant every other year. Fluid is cheap, it's inexpensive insurance and my experience has been if you keep all the fluids freshened, the components that rely on the fluid tend to stay in good working order. It also gives you a chance to to regularly inspecting just about all components of the car.

For a car of that age/mileage - I'd take a good close look at all rubber bushings (front/rear suspension) and at the rubber brake lines. 30 years old -- they've probably aged out even if they're not cracked and showing it.
