Ram 1500 4.7L overheating

Asked by Jarrod Mar 16, 2021 at 10:10 PM about the RAM 1500

Question type: Maintenance & Repair

My ram 1500 4.7L keeps overheating and I can't
figure out why. I have replaced both head gaskets,
exhaust manifold gaskets, ignition coils, spark
plugs, radiator and cap, overflow, cooling
temperature switch, map sensor, timing chain,
water pump, cam shaft sensor and the clutch fan.
When I warm up the truck to temp I check both
hoses from radiator and heater core and they are
all hot. I also made sure to burp it making sure all
air is out. When it starts getting hot it fills overflow
with coolant and spews out by radiator cap. I have
tried 3 brand new radiator caps with same result.
If anyone can point me in a direction good or bad I
would greatly appreciate it

How hot does it get in degrees F? Did you check thermostat? sometimes, I leave the thermostat out, just for testing. Did you backflush the engine, just to make sure nothing clogged? Can you check for combustion gases in the coolant? sometimes, you can take radiator cap off, start engine, if coolant starts rising quickly, you may need to check combustion gases in the coolant? Hope you don't have a cracked block. I can't think of anything else, at the moment. good luck
