Well you guys have heard me comment on our "ironman" work van, you know the 97' Safari, well it has finally hit a milestone, 500K! We got this van brand new in January of 98'. For the majority of its life it was run 300 miles a day, but in the last year we've added some stops and now goes 400 miles a day
Heres a brief history of its running gear:
-motor is original and has only been opened up once at 100K for a new oil pump, no new bearing!
-transmission is all original and is serviced every 30K by yours truely
-the original w/p lasted 325K, no kidding!
-the original radiator lasted 350K.
The oil is changed once a month and for about 1 1/2 yrs now, I've switched to synthetic w/o a problem
Oh I know what your sayin', yeah right, that thing has 500K on it, well heres the proof guys...
Drum roll please...
Also for the record, the van doesn't even smoke when you first start it up either, amazing! I called GM and guess what, they offered me a free oil change
I thought they might want to buy it back and see what they did right on this one
If you drove it and didn't look at the mileage, you'd have NO idea that it has HALF A MILLION on it
This is one reason why I'm a firm believer in preventive maintence
, but the safari/astro vans are THEE best vans that have ever been out. Reliability is the key factor in those vans, and although they aren't confortable, they won't get you good 1/4 times, and are pretty ugly... they are damn good vans. The astro/safari is the child of the parent Yukon/Suburban, which also says alot since 1974 suburbans still grace us on an everyday basis and the Yukon was just named most reliable truck in the world.
350 Correct? Either way those things last forever. 
Looking for another CSVT
