I never once flushed the coolant in my 2000, and I dont think the owner before me did either. Now my car.. I refuse to follow VW's recommended service schedule, oil changes and fluid top offs are enough for now.lol

 

I just check the coolant and make sure it hasn't evaporated or leaked and just keep running it. That **** lasts forever.

 

My brother's 96 Geo Prizm LSI had sludge in his coolant reserve...lol We aren't anything alike. I flushed it for him but not sure how much longer it could have gone.

 

I have lifetime coolant in mine so I should be fine forever lol

 

i changed my coolant quite unexpectantly. Durn ice + snow pile Now that i have a skid i'll change it every 50,000. One thing that would suggest in addition to the above is a tranny flush every 50k miles. Becareful on high milage truck, it'll do damage. Use synthetics too. Or change every time you sink the truck. Which means my truck is about due for gear oil change;p

 

Transmission how high of mileage?? i got 90,xxx, its been changed before once i think before mine.....should i change it now??

 

No don't change it now. It'll do more damage then good.

 

+1 on the "i personally wouldnt change the trans fluid at 90k"

-1 on the "I just check the coolant and make sure it hasn't evaporated or leaked and just keep running it. That **** lasts forever."

...No it doesn't

 

I am when I have the tools to do so. Because I dont always have that option I take preventative steps such as running synthetic fluids.

 

oil change every 2500
trans flush every 20k-25k
p/s flush when it looks dirty
coolant when it test bad.
fuel filter every 25k-30k

i work at a dealer so its easy and cheaper

 

Truck only has 3,000 miles on it, but I'll use Amsoil every 7,500 in the engine along with an Ea oil filter - Ea air filter when the original air filter gets dirty. Eventually all fluids will get an Amsoil transfusion, and I might even try out the Amsoil vitamins on myself when my next bottle of Monavie is gone.

 

Wouldn't even change it? or just not flush it?

I'm just about at 100k and was wondering the same thing.

 

I've always heard that it will stir up all the dirt and shavings that are in there now and cause more damage than good.
