I recently changed my heater core due to failure
smell fog and steaming Up windows . I used to run
low on my temp gauge not higher then the n on
normal now my car is getting to the L but never to
the red hot line I don't let it I blast the heater
thankfully its winter but I don't get it did I reserve
the hoses or could that be possible and I do hear
like a hissing noise coming from one of the hoses I
changed the clamp today but it hasn't helped
