Anyone ever run antifreeze thru a Q6 Tahoe?

[maddog2112]

I`m winterizing my 06 tahoe 5.0. Everything is going fine, but I`m not sure about draining the cooling system. I have found 3 blue capped drains so far and some just open and drain these. Others add antifreeze thru the engine after draining these blue plugs. I just can`t seem to figure out the best way to get the antifreeze throughout the system. I don`t want to get this wrong. Any help would be appreciated!!!

A easy sure fire way is to:
flush and fog the motor untill it stalls
remove all drain plugs, engine (2), manifolds(2) lower eng. circ hose(1)
reinstall plugs
remove large hose from top of therm housing and the 2 manifold hoses and pour in the A/F untill it comes out

I think I got it figured out. I changed the oil, filter, outdrive oil, fogged the carb and then opened all the blue drains, 4 in all, to drain all remaining water in the block. I took all the hoses mounted on the thermostat housing and filled every one of them thoroughly with the rv antifreeze, with the blue plugs reinstalled.I have a good feeling about it. I even fogged every plug hole and turned over the engine without starting it. Thanks for all the help.I`ll be glad to return the favor on this forum.
