Hello folks, I have a problem with heating.
When I start the truck temperature goes to 180-190 everything looks normal, but it doesn't blow hot. Both actuators work, as far as I saw there are no valves to open under the hood near turbo.
If I start driving 60 mph it gets warm, 65 mph warmer but still not hot.
Thanks!
