Replaced Radiator thermostat and hoses, car still overheation what could be wrong

overheating is caused by:
1. Coolant mixture is wrong has to be 50/50
2. Thermostat
3. Radiator cap
4. Obstructed radiator INSIDE the coils
5. Obstructed radiator outside
6. Bad water pump
7. radiator hose collapse

THERMOSTAT NEEDS REPLACED

Be sure the radiator is full of coolant, Start the engine when cold, while engine is running feel the top radiator hose. As the engine warms up the upper radiator hose will suddenly get hot when the thermostat opens. If the upper hose stays cool, the thermostat may be stuck closed. If thermostat is stuck closed It must be replaced.

Without knowing more about your car, this is all I can recommend.

CAR OVERHEATING

There are many possibilities for car overheating.

Faulty thermostat clogged radiator/plugged radiator, radiator hose worn out. Coolant running low. Low coolant pressure. Faulty temperate sensor.

tanks held in with crimps on aluminum radiator

of that radiator
not as expensive as a new radiator

replace the thermostat

pressure is too much on that crack for any diy repair product

pop off hose at the wrong time =cook the motor

thermostat and likely the serp bel installed wrong
and is spinning the water pump backwards

replace radiator cap system depends on good pressure to keep from overheating

try checking the hoses for blockage,and if not that make sure the fan is working right as it might be the fan cluch,or your water pump may have went out,best of luck

Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.
