How do I know if my Coolant level is adequate

Txhemirt · Apr 23, 2017

I recently changed my thermostat out and I am concerned I may not have put enough coolant back in. Is their a way to check that I have put back enough?

If you're not losing coolant out of the reserve tank, you should be ok.

aaahhhh, I usually take the radiator cap off when it is cold (the engine is cold).........someone else may have a more creative way.

So what exactly are you looking for when you do this ? Being completely serious here lol

Without having a refill funnel or vacuum filler; fill the radiator to the top, let air escape, fill to top again, air escape.... Repeat until radiator is filled to the top of the neck. Add to overflow tank about halfway. Start engine & let thermostat open. If the gauge goes past 3/4 hot, either coolant is low or there's an air pocket that's trapped. I rarely see them get past 215° on a 5.7. Once thermostat is open, you'll see the gauge drop down to operating temp (195 ish). Let cool down completely, recheck radiator & overflow. Top off radiator if needed & fill overflow to indicated max level. And obviously, don't remove radiator cap while hot.

So if I am looking into the radiator tank when I remove the polished/chrome cap on a cool motor the coolant should be visible if full? I put a 180 stat on and have not noticed it get hotter than 185. I added about 2/3 of a gallon after changing out thermostat

This is the coolant I used. I did not mix it with water. This is what dealer said went in to the 2016

That's the concentrate, it needs to be mixed 50/50.
