Got my ScanGauge 3 Today! Nice unit how do I setup AT temp?

I got my ScanGauge 3 today. Nice unit, very easy to setup, navigate and update. I really like the larger display. Two questions...

#1 anyone know how to setup ScanGauge 3 to read AT temp?

#2 as you can see my coolant temp is on the high side. I'm in south Louisiana so it's about 100deg everyday now. For a couple months my temp has been running between 186-196 normal driving. On interstate running 2500-2700 RPMs it's running around 200. Previous years my temps were about 184-195. Anyone else's 1GR-FE running that hot in high temp weather?

 

Find x-gauge programming, and try these codes.

Those temps especially with an ambient temp of 100 degrees I would not consider high. You probably have high humidity as well.

 

Don't know about the SG3 but the SG2 you had to look up the X-Gauge codes on ScanGauge's website and enter them in your unit.


Mine usually runs in the mid 190s on a hot day, 200 isn't too concerning but you may want to check your coolant level, condition, and make sure the radiator is clean.
If the coolant hasn't been changed/flushed in more than 5 years it's due for that.

 

I changed water pump last spring, so coolant is pretty fresh. When I did my engine swap in 2018 I put a new OEM radiator, hope that's not already failing Might do another flush anyone got tips on easy way to tell if I have blockage in my radiator?

 

If your coolant is clean and fresh there shouldn't be any way for the radiator to get plugged or restricted internally.

Like I said I wouldn't be concerned about a 200 degree engine temp at 100+ degree ambient temp but it never hurts to look under the hood and check things over.
