I need to service the radiator fluid on 3 GM's.
2000 Silverado 1500 5.3 with under 50k miles.
2003 Tahoe with 98k miles.
2005 Malibu Classic 2.2 with 55k miles.
All have the original fluid.
I want to use the Prestone Flush kit with the attachments for a garden hose to flush.
Which fluid should I use? Dex-Cool or Peak Long Life?
Other recomendations.
In all three vehicles the fluid does not look dirty.
Does Napa still make NAPA KOOL and is it compatible with Dex-Cool?
Thanks.
