Kind of a dumb question, but here goes. I just tested my coolant yesterday, and it was good to somewhere between 0 and -5 degrees. It's gonna be colder than that up here in a few days (yay) so I took a gallon of coolant out, and put in a gallon of antifreeze, so the mix should be good to -25 or so. I wanted to make sure that it mixed, so I idled the car for about 40 minutes while having dinner. The temp gauge I have is really unreliable, but it went up to an indicated 200. The car usually cruises at 210 or so on that gauge on the highway in summer.
I couldn't hook up direct scan, and I'm not absolutely sure whether it has the stock thermostat or a 160 degree one. I just know that DS usually reads 170ish while cruising,and 190 if I'm in the staging lanes.
I just wanna make sure the coolant from the engine mixed in with that of the radiator (where I added the new coolant). I let it idle forever, but that was at a 15 degree ambient temperature. Now the thermostat has always worked before (car never overheated) so it would've HAD to cycle the coolant in the time I was idling it...right...??? I'm an idiot, I thought the mix was fine until I tested it just now, of course RIGHT before the coldest day I've ever seen. Just looking for some input, thx.
