Slow Cabin Heating in my 2012 Camry
As a test, I put this additive in the coolant overflow tank and not the radiator as the vehicle was warm and didn't want to get sprayed when I open the radiator cap: https://www.hyperlube.com/ca/product/qu ... directions. I just put this in yesterday and am not sure if it made a difference or not. Time will tell.
I had read somewhere that some people suggest to reverse flush the heater core and when I asked my mechanic that they didn't want to do it. Their reason is that the water will mess up the coolant mixture and the Toyota coolant is already at 55/45 mix
Just to be clear, when the heat from the vents is hot, the car gets very warm. When I put my fingers in the air vents, I can't keep them there for long as the heat feels like it is burning them.
As an aside, is it normal to have the air pressure lower when it is on heat vs. cool. For example, if I keep the fan speed to the middle and set the temp to the left (cold) I can feel a blast of air. If I turn the dial to the right (all the way to hot) the flow of air feels diminished. Both the cabin filter and air filter are new.
What would you suggest?
