Hello All, I'm planning on doing a coolant flush/change on the Tahoe fairly soon. I haven't had a chance to get under it yet, but I had heard that there isn't a drain petcock on the bottom of the radiator. Do you just pull the lower radiator hose off to drain it? What about getting the...

Hello All, Just replaced the gear oil in the rear end last night but wasn't sure if I needed to add any friction modifier as well. It has the Eaton locker (G80 I believe) in the rear and I figured it would be easier to add the friction modifier if needed. I couldn't find any Mobil 1 in my...

Hello All, Just curious what programmers people have tried. I'll be putting on a S&B CAI and Flowmaster exhaust this weekend, so I am starting to look at power programmers as well. Are they worth the money? Currently, I've been looking at the Hypertech Power Programmer III. Has anyone had...

Can someone help me find where I plug the factory trailer brake harness inside? I'm setting the Tahoe up to pull our little travel trailer this weekend and I don't know where to plug the wiring harness into. Thanks Alot...
