The dealer is correct.My coolant temp runs between 215-225 degrees,depending on driving conditions.Tran temp is about 180,oil temp around 212,oil pressure at 35or so when cruising,20 at idle.

Mine runs around 194°-199° this time of year with temps under 50'ish.

 

This thread is a little old but the question is still valid. Here is a photo of my instrument cluster while towing. The rear end is 3.21 and I use the tow/haul mode.

 

One more photo of HOT WEATHER towing.

 

What was your curb weight with that trailer? I have 2016 crew cab 3.6, 3.21 and my max towing I found was 4590 lbs. Is that number accurate would you go under? I saw online most people should run to about 80% of their max tow capacity. Just curious on your real world expierence. Thanks!

 

My 13 v6 does the same thing. But while I'm driving around 75-80 it will move between 215-226 degrees. I want to say it's the grill shutters causing the increases and decreases. I just want to know if that's normal.

 

I don't know if the grill shutters are doing that but your temperatures look OK to me.

 

I see 215 - 230 as normal.

 

yes I see the same thing. Example I was towing 5000lbs up a 5% grade in 95 degree temperatures. I was at 228 temp. I got a little worried but it never really got any worse. AND to add to it I was at 6800 elevation. The truck was working and did a pretty good job. When I got back home I went to the dealership and talked to the guy who said he works on all of the Pentastar motors. He said the motors have higher degree thermostat. It is fine to see temps of 205 to 228 when running. If the alarm goes off... then there is problem.

 

I have the 2016 1500 3.6 ltr and our 3 way coolant valve was leaking coolant... replaced it and a few days later the new one went bad... replaced again and a new thermostat and seems to still be running hot! Coolant temp jumped to 236 and the temperature needle would bounce a lil bit past the half way mark... soo confused n don't know the what the issue is! It has 54000 miles n while changing the parts I flushed the coolant and added new and burped the system as well!

Any help would be greatly appreciated... we have no clue what it can be...

Also no check engine lights have come on at all during this!

Mind is also doing the same put a new radiator in and thermostat burp it like 5 times already... Help plz could it be the water pump

 

After replacing the 3 way coolant valve 3 times... and replacing the thermostat it has not had any issues since! So during normal driving the coolant temp is between 200-230! Found out that these engines do run at the temps normally! When going uphill and towing a 2500 pound pop up it will be at 230 but hasn't got any higher then that! I'm not a fan of how hot these engines run but after a lot of research this is normal! The 3 way valves are plastic 'n a real bad part for these engines... because the valve gets stuck open which is why I had to replace it twice within 2 weeks!

Hope this helps! Let me know if u need anything else!!

Where is the 3 way valve located

 

When the motor is on... can u hear a grinding sound coming from the water pump? If so then the bearings in the pulley are bad and the water pump needs replaced... I thought I was going to have to replace mine but it was just that 3 way valve!

So I should replace my three way vale...

 

The 3 way valve is super easy to replace but they are made of plastic... the replacement we got from O'Reilly's ended up being bad after 3 days of it being on and it dropped all the coolant again, took it back and got a new one that also went bad after a week... we are on our 3rd one now and it seems to be holding up as it has been 3 weeks now!

Make sure you burp it all the way by placing the front end of the truck pointing up a hill!! Will update this post if something else happens! When we got the 3rd replacement valve we bought a new thermostat just incase but I'm sure the old one was just fine as I tested it!

Good luck and will be happy to know that it gets fixed for u as well! Be blessed!!!

 

So what ur coolant temp now

 

Stays between 200 and 230.. hasn't gone above 230 and only gets to that if going up hill or towing up hill!

 

I changed the pump instead and still doing the same

 

 

How long do you burb
it for

 

Burb

 

It's not a time limit that you burp it for... just until u think all the air is out of the lines! There are a bunch of videos online that show how to burp the lines properly that I had to use!

 

runs between 215-225 degrees, depending on driving conditions. Tran temp is about 180,oil temp around 212,oil pressure at 35or so when cruising,20 at idle. but the question what would happen if I add two electric fan to move cooler air around would it help
