Are the heater hoses so hot you can barely hold onto them?
This could be a heater door--actuator motor problem in the heater. As the heat is making it into the heater box
if they are barely warm---i'd investigate the thermostat 1st
i hate to throw this at you --- but I feel obligated, as this could be the condition. But maybe not (we hope). Failure to consider it, may cost you your engine.
. Do your other checks, if things are not working out.I'd stop driving it, till you get this checked
thing is----if the water pump is having an issue----not only are you cold in the cockpit----the engine coolant may not be circulating (or enough)
sometimes water pumps have plastic impellers---sometimes the same kinda pump from another parts may be offered with a metal one----sometimes the parts store may have both, with different warranty's or prices
personally, if available, i'd get pump with a metal impeller
i dug a little deeper for you---"advance auto parts" has "2"---only one of 'em allows me to look at the back side on their site.I screen shot it for you. See my 1st pic. This one is plastic!
I have taken several pics of pump failures with a plastic impeller. Keep in mind these are from different vehiclessee the rest of my pics. Especially the one that is just cracked (i wrote captions on it)
return with good news
