    2016 Cooling Issue

    So my 2016 RAM about 2 years ago had the radiator replaced (poor dealership Water Pump Recall).

    Cooling system has been fine up until about 2 months ago. We were in a drive thru waiting to get our order and the Engine Temp warning came on. It was about 90 Degree's so we were sitting still blasting the A/C.

    I pulled the truck over opened the coolant res, and I got bubbles and lots of pressure release. The level came up right to correct level.

    While driving the Truck runs @ 188-192.

    When I sit and idle the temp slowly creeps up will get to around 220+....

    When I drive off the temp comes right back down. The Coolant level isn't dropping, it stays up. No leaks on the ground etc...

    After I drive it for a day I will open the res, and it will let out some air, and bubbles.

    Yesterday driving home (23 miles one way back roads) I got a low coolant warning. I was keeping an eagle eye on the temp ran like always 188-192 driving. Got home and released the pressure and level came right back up to the seam line.

    Any thoughts?

    Do i got an air leak?

    Any thoughts?

    Thanks everyone!

    Is your fan engaging audibly when the coolant Temps rise?

    The Fan clutch is what engages to cool the engine when at a standstill.

    Check your fan clutch and make sure the radiator isn’t full of debris and such blocking air flow.

    Agree with the above, also make sure the coolant level is at the seam when the engine is cold.
