I recently bought this 1999 Suburban with a 5.7L Vortek, I have been stalking the forum learning lots from you all. I am not too experienced with auto work, trying to learn
I’m working on changing the fluids, first of all the coolant, which was low (reservoir empty), and lots of sludge in the radiator cap. Existing coolant is orange (DexCool?)
I tried opening the petcock, but it does not look right:
Might be broken, or maybe a previous owner installed that? Any ideas how I can open this to drain the coolant?
The next thing I tried was removing the lower radiator hose to drain from there. I opened the clamp, but the hose would not budge. Any ideas on removing a stuck hose?
Thanks!
