Anybody out there still doing preventive hose/belt replacement?

I was wondering about this. I talked to a guy the other day that told me he replaces all his hoses, belts, thermostat and water pump every three or four years. I remember growing up a lot of people did this, but I hardly know anyone now that still does it.

I've got a 96 Buick creeping up on 200k and I've yet to replace any hoses. I did the serpentine belt last month but truth be told I could have gotten another year or two out of it. When the intake gaskets blew I did the water pump because I had a free new one. T-stat's original.

It just seems like today's rubber technology is way better than it used to be. I can go over 100k on cheap, never rotated tires and never have a flat. Could you have done that on a premium tire 40 years ago?

I'm just wondering if by doing these old preventive maintenace procedures on today's newer vehicles is overkill. If I was to do the above routine every three or four years it would run me about five hundred bucks each time, about fifteen hundred dollars now and it would have been for nothing.

Watch, now I'm going to be going to work tomorrow and the hoses will all blow at once. Knock on wood.

My last truck original hoses went to about 400K

I'd say a good 300 would be fine for Toyota in light of my recent experience.... Belts when they go bad
good belts about 100K and bad ones 30-60K
thermos probably high 200K to low 300K
whe I changed mine, posted here somewhere
it fell apart
still worked
but fell apary all the rubber and it had gotten all inside my engine ;D

Maybe a good idea to do it at a fixed schedule but as long as they are not bloated or hard and cracked

Ive tried to find a schedule that was honest
and have not located on

if anyone knows of one for Tacomas, I'd be very pleased to have the info.

fwiw, when I had my toyota, it had a non-interference engine, so I didn't worry about the timing belt. I finally changed it because i was doing a water pump & such, but the belt had 118,000 miles on it, and you're "supposed" to change at 60k.

My mitsubishi's are interference engines, and I'll do timing belts at 50k. They're really not that difficult to do. The thing that takes out most 4G63's is the balance shaft belt. It's this small little belt that spins a balance shaft at DOUBLE the RPM of the crank- and typically if it "looks good" mechanics don't replace it when they do a t-belt, which frequently leads to failure, and bent valves (the balance shaft belt wraps around the timing belt and blammo). Of course it can happen on a new belt as well, so i'm simply eliminating my balance shafts.

As for hoses, I'm eliminating every rubber hose on the car and going to AN/stainless steel braided lines. My fuel system is all either hard line or stainless, as are the clutch lines, etc. Finding good -22an fittings for radiator hoses is kind of a pain, as is getting fittings put on, but peace of mind++

On the talon, I only have a timing belt, and an alternator belt. I carry a spare alt. belt.

I'm interested in how you are going to attach the AN fittings to the WP housing and radiator??
