Jeep Cherokee Vent Odor?

Question

My 2000 Jeep Cherokee has developed an awful odor coming from the interior vents. The odor smells like a hot radiator, obviously coming from the heater hoses, but my temp. gauges are fine. I recently drained and flushed the radiator, installed new coolant, but still have the odor. Also, my interior glass frequently fogs up and the defrost setting does not clear them. A friend says I need to clean the heater core. Any ideas here?, Thanks!

Answer 1

Your heater core is going replace in before it makes a puddle on the floor inside. If the windows are fogging up and you smell coolant inside the heater core is on its way out. Nothing you can do but replace it.

You need a new heater core, smell and fogging windows are the first sign, next you have coolant soaked into your carpets.

there is a pin hole in your heater cord. that is where the smell is coming from. and causing the inside of the windshield to fog up GUARANTEE.
