I wasn't going to wait for the secondary fan to kick in, because as soon as the fan came on at 180 the temps dropped right back down.
There was a little warmth blowing from the vents but hardly detectable even when the car got up to 180 degrees.
On a 50 degree day, 15 minutes is about right. My Lt1 takes over 5 min. to get to 100. Kicking the fan on at 180 is really low, means your fan will run a lot in the summer. If it was mine, I'd reprogram to 195. I don't even hit my manual switch at stop lites unless I see 205.
To see if the heater control valve is working, warm up the engine with the heat off, touch both hoses going into the core. One warm, one cold? - The valve is closed. Turn on the heat, both hoses warm?- the valve has opened.
