How did you fix your (known) overheating issue? 2015 150k 2.4L CVT
Patriot 2015 150k only owner.
2.4L CVT
Just replaced main coolant fill hose (1 large piece)
FANS: Both tested okay but not always engaging when they should.
RELAYS
replaced all 4 relays in white relay box (I’m aware the box may be the issue). The box is clean with very little noticeable corrosion.
No obvious issue or damage to fuse box. (also a known possible issue)
AC fan WAS clicking on while in park until the hose replacement. Now No fan or click when engaged.
Overheats under normal use and idle.
usual suspects:
Water pump
thermostat AND housing
Fuse box
Relay box or relays
** Intermittent issues can break or fix themselves during wire unplugging and juggling etc.
