Check Engine Light On With New Stat....170*

hey guys......

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?

thanks.....

2007 Red Rock.... slightly modded, but BAD 2 the BONE!

You got the CEL after the tstat install? Do you have a code reader to see what CEL you have?

....no,I just got the truck Monday, it's got 700 miles on it.

I did the front scoop mod, the brake duct mod, the fam mod, and the
170* T-stat.

want to squeak a 13.0 tomorrow, if at all possible??????????????

If I disconnect the battery and turn key on, and tap the brake,
could it reset and be ok?

thanks,

Just disconnect the battery, tap the brake and reconnect the battery.

Be nice to know the CEL code it threw, I dont know any other way to clear the CEL then with a code clearer of disconnect the - battery for 5 minutes.

Same CEL code with my 170 in cold weather.....turned cold in Charlotte and got another CEL. Hooked up the Scan program on the laptop, same damn thermostat code as usual in cold weather. Next winter may change back to a 180 and possibly use a 160 at the track.

All goes back to tuning too, if we could get in there and change some ECU parameters these idiot lights would be a thing of the past.

Wow 160 it will be an animal!

....thanks guys, I will disconnect, and see what happens.....

I guess I will try a 180* next week, and I don't think the 170 will hurt it.

It wont hurt it but the ECU doesnt like it and will keep throwing the code.

...like I said, it never tried to burn the tires, or had the TC light flash on
when I have launched it previous to the stat.
