Check Engine Light On With New Stat....170*
The thermostat was cake to install.......
I intended to order a 180*, and apparently gave the store wrong part #.
I got the 170, and after some reviewing on here, I decided to install anyway.
I followed directions, and after done, idled the truck for 10 minutes, and
CEL instantly came on, I topped it back off along with collant bottle overflow.
Nothing leaking, so took it down the road to get up to temp.
ran it hard, and boy, it made a difference. It never tried to spin the tires before.
I ran it up about 4 times, and the indicated temp on the monitor system
finally went to 204*.
I turned truck off & on a few times, CEL still on.
Came back to my house and burped radiator....
....here I am, and I don't really want CEL on all the time.
Should I disconnect the battery?
any other thought?
