I have an '03 Tahoe 5.3 2WD (105k miles) and recently aquired '05 Suburban Z-71 (76k miles), both with the original coolant.
I plan in March to service both coolant systems using a Prestone Flush Kit.
What coolant should I use?
Licensed Dex-Cool?
Other?
Should I use an additive corrosion inhibiter? If so, which one?
Thanks!!
