    You are thinking Ram used Dex in his truck? How can you trust that knowing Ram used Orange HOAT for many years prior. It is a quagmire, no way to trust that orange coolant is either HOAT or OAT. Time for a full flush anyhow.

    Well hell. I'm surely nervous now! I'll pull some out I guess. Or just be very careful to catch everything going that spills when I do my thermostat lol. Let me go snap a picture to show yall.

    OK so it's in the 40s outside so it's cold enough to be low in the radiator top but perfect in the reservoir. Anyways. Here's some pictures

    Here's the thing, if it is HOAT, it is time to flush anyhow. You can get a kit. Go back at it with distilled water after a long hose flush, be on the watchout for soccer mom's with camera phones. Put back whatever floats your boat. Your truck wasn't made for Dex, GM's have done specific things that allow them to run dex. Read that coolant link, Ram OAT took the bad stuff out of Dex. It is like a dex clone but w/o the bad stuff, forget what it is called.

    I dont know a better way to flush, I am all ears if anyone does. Capture the old coolant best you can, I'm sure someone takes it.

    O'Reilly says to run oat but offers dex cool. Wtf? I wish I could just find a store where I can pull the shit off the shelf and walk out! Sorry. Frustrated at the moment.

    I'll do a flush and fill for sure. Do yall suggest pulling the heater hose or what? I've honestly never kept a vehicle long enough to worry about it. I usually just drain the radiator, hose it out, run distilled water through it, refill and go but some say you should go through the heater core etc

    I will stay out of this! You have plenty of help! But I agree with Burla --->It is time for a drain & Flush.

    Perfect time to pour back in a OAT coolant.
