well i had my heater core disconnect due to smoke was coming through the vents raising my cooling hand up so then my friend did a bypass for now and sense he did that the temperature gage move from the middle to the top back and forth but its not overheating when i drive it whats the problem and also my reservoir jug states full to the top and also my i hear a squeaking sound when i drive but when i hit the brakes its stops.help me i don‘t no much about cars just a little lol
well since the previous answerer got everything but this the needle is fluctuating because you have trapped air in the system so to fix park the car on a incline front facing up let cool top off radiator with coolant good luck
have no idea why the Gage goes up and down, but you certainly need a new heater core. it's a miniature radiator that also helps keep the temp down. the squeaking brakes is telling you that you need new brake shoes or pads and maybe rotors turned down (shaved). that noise is there for that reason. it's a warning. good luck to ya.
clutch and throttle. try pulling clutch and holding throttle at same time with same hand.
