What if theres coolant keep bursting out of my overflow thingy after speeding like when i park my car i look in the hood theres splashes of coolant all over and when i check my radiator theres no coolant anyone knows whats wrong?

 

bad radiator cap possibly...but it sounds like you have a head gasket problem. youre boiling the coolant and due to the pressure from the boiling it is coming out the overflow resivore. just my thoughts. tuff to to say without diagnosing the issue. i would start by putting a block tester on the radiator after you fill it with coolant again. if the block tester detects exhaust gasses in the coolant you have a head gasket blown ...or the block is cracked. but its usually the head gasket thats bad. start with the block tester

 

auright thanks ill try that
