My 2017 MX 13 is leaking coolant from the oil cooler at bottom edge close to block side where it mounts
I went from Dallas ( I thought I saw coolant drips on the ground in Dallas) to David City NE. to Syracuse NE. and it had used about a half a gallon of coolant.
I have a load going to the Knoxville TN area.....my thought was to try and get delivered and then try and get it fixed......or will it just get worse and spew coolant like a geyser ?

I have a 2017 as well and from experince it will just get worse and dump all your coolant. Been there done that. Paccar in their infinate moronicism decided to make the fitting PLASTIC with PAPER gaskets. Have not just the one leaking but its twin and the one on the back of the block too replaced with brass fittings with a rubber gasket or else yours will look like this. And yes you gotta do all 3 no matter what. Mine blew 1 by 1 within 100 miles of each other.
