i was driving just now and my car over heated, i popped the hood with my car on and saw coolant spewing from my reservoir. i waited 10 mins for a cool down, checked for leaks from radiator and hoses and nothing. so i refilled my raditor and reservoir so i can get home and same problem ( reservoir spewing coolant and overheats )

im thinking i have preasure problems maybe change my rad cap. has this happen to anyone ? i drive 93 del sol si, thanks for any help

 

Take the cap off and let the motor run idle for a while to let any air out. Make sure you did not overfill the reservoir. This should fix your problem let me know if it works.

 

thermostat? water pump not working? I'm sure someone here can say for sure.
