Hey Scotty I need some help, my racing civic last night started to have issues with the heater system. When I left work last night and was at a stop light, my heater blew Luke warm air but when accelerating it blew hot air. Now I use to have that problem before my car overheated and after doing the head gaskets, timing components and changing the coolant and bleeding, car stop overheating and it it blew hot air like it was a new car but now it having that issue again. The car is not overheating again thankfully. I went somewhere today and it kept having the same issue. By the way it was having the problem while in operating temperature. So I look at my coolant reservoir and it was full. Idk if that’s normal so I let the car cool off and went back to my house and several hours I went back and look at the tank and still full. Over the max. I open the radiator cap and like it had push a quarter of the coolant from the radiator to the tank. What could possibly be happening? Could the piston slap I mentioned on last post be creating a domino effect and soon create serious problems? Help! Also thermostat has been replaced with original and the radiator has been replaced.
@scottykilmer so it’s been 3 months since it happened and for some reason on the next day I check, it look like 1/4 of coolant went to the reservoir and almost overfill so I just sucked out the excess coolant and refill the radiator and it never happened again.
Well often it's hard to get all the air out of the system. When you work on a car. You might pay a mechanic who has a vacuum radiator machine where it sucks all the air out. Then you close the valve on the hose, remove it from the vacuum, stick it in a gallon of coolant. Open the valve and then it fills itself up by suction. I would start there cuz there's so many things could possibly be wrong. You would also want to check my video how to tell if your head gasket is blown Scotty. It's on YouTube
