Do yourself a favor. when you do flush it, switch to the green coolant. the dexcool eats the intake gaskets. change it about every 3 years. i have 7 obs's and all are green coolant and guess what "NO INTAKE GASKET PROBLEMS EVER ".

Why top it off? Why get concerned about the coolant now?I'm going to replace the engine and entire coolant system probably within 6 months. I'm just looking to top it off for now as I won't be driving it much until then.
Well, I have never tried. I like the good old fashioned green Preston. To answer your question though, you can run any collamt you want to, IF, you completely flush out everything in the system. Prestonakes a flust and fill kit that back flushes the system by giving you a way to hook up your garden hose, and flush the whole system through the filler neck of the radiator. You have to install a tee in the heater hose. I have been using these kits for many years. They work grate. Thing is, it is critical to be sure that your system ONLY has water in it before you change you coolent type.Could you use the pink toyota super long life coolant in a 98 5.7 vortec?
I understand your point. Why now? Well, when I bought the truck, I picked it up at PO's home. I didn't have any fluids to top it off, nor would I have felt right doing maintenance in the PO's garage (and I don't think he would have aprpeciated it).Why top it off?

Put the cap on, shut the hood. Come back when you're ready to yank the engine.
DO NOT mix Dex with anything! Top it with Dex or flush and refill with the green stuff and distilled waterNot sure if it’s cold where you are, if so, I’d probably just get cheap autozone 50/50 to add also to overflow tank. Just adding water to that in freezing weather not good!
