i was wondering what i should i do to get the water to flow into the heater core on my car, car did have heat one day then it suddenly quit having heat, and sometimes the temp gauge get over to l in normal and i think that a little too hot, so how can i fix these problems, coolent is fine and radiator has pressure and t-stat opens fine

My car is doing the exact same thing. What did you ever find out about it? I would also like to know.

i think you have to backflush the cooling system and replace the heater core hoses.
THE CAUSE OF THE PROBLEM WAS THE USE OF STOP LEAK PRODUCTS, THUS THE COOLING SYSTEM NEEDS TO BE FLUSHED WITH QUICK FLUSH PRODUCTS AND THE T-STAT NEEDS TO BE REPLACED
