you have a phase 1 ej25 engine with blown headgaskets...don't continue to overheat it...get it fixed pronto
Is the cooling fan[s] coming on? is the radiator full of coolant ?does the engine have a blown head gasket or cracked head? Why did it need a radiator?
Low coolant? Cooling fans not working? Water pump not circulating coolant? Radiator plugged or restricted?
Check the timing.
You probably have a cracked head gasket!!!!! You probably have a cracked head gasket!!!!! Check coolant to see if there is oil in the coolant this will prove it or if you have foam in coolant overflow check coolant resevior cap
You either have a cracked block, blown head gasket, or intake manifold gasket leaking coolant into the engine oil. You have bad problems.
have the engine timing checked. if the timing is wrong the engine will overheat, are you loosing coolant?is the fan working, is the water pump working?
You need to check coolant temperature sensor and the water pump.
Blown head gasket?
when overheating occurs at highway speeds the cause is usually. a radiator or coolant circulation problem, Check for a restricted or clogged radiator.
did you use the right anti-freeze or you may have a bad fan/fan switch
your radiator needs to be replaced
Low coolant Defective radiator cap Radiator plugged or air flow restricted Coolant fan sensor defective (should operate fan if coolant temperature exceeds 235 degrees)
