Q: Car overheating

asked by on August 24, 2017

My car is heats up a bit a little past normal temp. Today I checked the coolant level , and I was bleeding with the radiator cap open and car hit normal temp with the heater on high and the coolant would burst up and overflow and would suddenly go down like if the system sucked it in. It did this repeatedly.

My car has 236000 miles.
My car has an automatic transmission.
