How often do you flush/replace the Radiator Coolant?
 

Like the title says, how often should this be done.

Thanks

I think the new stuff is rated to like 100K miles. I wouldn't bother with it until 50K at the earliest.

I always recomended the Radiator flush ay every 50,000 mile intrevals at my shop.

I do it every 2 to 3 years. I run my truck hard during the summer and it sits in the garage during the winter.

every time you swap motors, change cams or pull heads:D

Do you need to put in those disolving tablets? My father was told he needed to with his 97 suburban...

you dont need them, but on a 97 I would put 2 or 3 in if you have some but if not I wouldnt sweat it...

change heads!!!!man that stuffs reusable...or just top it off lol.:devil:

You shoulden't need the pellets unless you are experiancing a small to moderate leak. If you need them this is the GM part # 3634621

my thoughts exactly.
