Yo... My car warms up normally and after i drive for awhile it has begun to slowly overheat all the way until the temp gauge needle surpasses the "H" ... of course i stopped asap, but the first time was due to lack of coolant... (yea .. im a dumbass).... anyways it happens now everytime i drive.. i have to put my heater up all the way and not accelerate really just to drive it without overheating. i am going to install a new thermostat soon but im unsure as to if that will help.. any ideas whats up here?? i am growing tired of my D15B7 i think its time for a b16... gonna get a loan for it.... thanks for any comments.
