I've been reading too much about different coolants and now I've just about confused myself. I recently bought a 2000 Silverado, and I'm changing all the fluids. It has the 5.3L and is totally stock.
I was originally planning on using OEM Dexcool, but the stuff in the radiator is not that. It's sort of green like old school coolant but also a bit on the yellow side, possibly "universal" antifreeze. Appears to be clean but I'm changing it anyway. I'm going to flush it out completely with some radiator cleaner and a bunch of distilled water, so there will be no original fluid leftover.
Can I use the red ELC type coolant like they use in diesel trucks with this system? I don't know much about Dexcool other than there is controversy over it so I'd prefer to use something else and this is my first LS based engine. Will it be OK with the iron block/aluminum head combo? I already have some ELC coolant I can use leftover from a different truck and it seems like it should last a long time.
