New flex fan and shroud

OK, I am in the middle of eliminating things one at a time. I took the old thermostat out and put a 160 degree thermostat in. I was also looking at my aftermarket temp gauge before I started the engine and noticed that it is not dropping all the way to zero. The lowest reading on it is 130 degrees and the needle sits above that before I have even started it. Seeing this, I decided to hook up the stock temp gauge to a sending unit. I took it for a drive. The aftermarket read high compared to the stock unit. The stock unit never got above the half line on the gauge and even went down to about a quarter reading on the gauge while driving down the road. Aftermarket was reading about 220 and about 210.

Seems the aftermarket gauge is bad, but I am wondering if the location I have the sending unit for the stock gauge is reading low because of where it's at. Do you think the sending unit location is OK. Stock is on the right(drivers side) in the pic. I also took pics of the temp gauges after getting back from my drive.

that's where I got my stock and after market gauge senders is in the water pump housing as you do

there's no other place to put the senders that will read correctly

Had my cousin bring over his infrared gun and the stock gauge is reading what the gun reads. The aftermarket was reading 200 when the gun was reading 130. Guess we found the problem. Thanks everyone.

Well hush my mouth and fill me full of chitlins-a stock gauge was correct over an aftermarket one...
