Help car overheating
I have a 2008 Mazda cx-7 that I have recently replaced the radiator, thermostat, temperature sensor, and it’s still overheating the head gasket is good from my knowledge no water mixed in the oil no water or smoke from exhaust
i can idle the car all day fine but as soon as I shift into drive and move it pegs to hot ive released all air in the system with the car cold I can’t even start the car without coolant spraying outta the radiator with the cap off like a geyser and with the car running all the fluid seems to completely fill the overflow tank I remove all the fluid start it again and the overflow tank fills again I’ve also replaced the thermostat again with a oem with no change plz help

Welcome to the forum
Ok well you need to do a coolant chemical test. post the results.
READ the how-to so you do not contaminate the test chemical and get an accurate result indicator.

this indicates blown head gasket, combustion gasses forced into coolant
