Q: Can a bad air blend acuator cause the engine to overheat?

asked by on October 29, 2017

I have replaced everything in the cooling system the radiator,water pump, fans,engine coolant temp sensor, cooling fan relay, resevior tank, and the thermostat. With that said it still heats up. It takes a while to heat up but it does and if I stop and let it idle it cools back down. There are no leaks but It spits the coolant out the overflow when it heats up. I don't get it and it's driving me nuts! Any suggestion would be greatly appreciated!
