2014 RAM 1500 with ecodiesel coolant leak

[kwijibo]

My son has 2014 RAM 1500 with a eco-diesel. A couple of weeks ago a code came up which said there was a fault with the thermostat I don't remember the code number. Wanted OEM part and since none of the local dealers had the part we ordered the thermostat from Rockauto. We also ordered a radiator cap from rockauto the original one was not coming off when it was unscrewed, something not quite right with it. So a new cap was ordered and it was not OEM. So now there are times when it works just fine. Otherwise it will spill coolant from the over pressure hose on the coolant tank. No rhymn or reason to when it will spit out the coolant. Wondering if I should be trying to track down a OEM coolant cap. Temperature is running where it usually does. Just a note I'm not a mechanic but have owned a few ford's so have gotten my hands dirty a few times.

Motorad cap?

The only way to find out is to switch the cap to see if that was the problem. But then it could be other things, the cap would be a good starting point.

The cap we put on is a Motorad cap. We were also thinking of switching back to the old cap.

Hope it isn't a headgasket

A very common sign on the larger Ram trucks that puke coolant is the head gasket. Usually the truck is tuned but nonetheless that’s the issue.

Just my $0.02

The installation of aftermarket cooling system parts is strictly verboten! I have never had good luck with aftermarket cooling system parts.

We were able to locate a OEM part from a dealer today. New cap was installed and fingers are crossed. we'll see what happens.

it's been 3 days with the new OEM cap and so far no drip drip drip on the driveway.
