My Subaru outback as engine problems. Engine light comes on the vehicle over heats. I have replaced the engine on the vehicle 2x. Both times the engine over heated. This is a 2011 outback 2.5L engine. Any suggestions on how to fix this problem? New thermostat was installed.
Read the OBDII codes related to the check engine light and report back to this forum.
In the meantime:
With the engine warmed up and running in Park, feel around the surface of the radiator. If some spots are distinctly cooler than the others, the radiator has a blockage and needs replacement.
Is the coolant level dropping and you have to keep adding coolant, or smell coolant when you open the hood, you have a leak. Look for stains around the center of the water pump or liquid coolant dripping from somewhere under the hood. If you can't see anything, have the cooling system pressure tested by a mechanic.
Does the dashboard temp. indicator climb a little above normal, then drop back to normal? If so, replace the thermostat.
Does the whole hood of the car become extremely hot, especially when stuck in traffic or after parking the car? If so, replace the radiator fan.
Check for a blown head gasket. Use this test kit.
