I am having issues with the heat in my truck. The heat was not working at all and I changed the thermostat and it seemed to help some but still not blowing hot in the cab. It got alittle warm but still not right. The top radiator hose is hot as it should rbe but the bottom hose is ice cold. What I am asking is Can the waterpump cause these issues or not?
The truck however is not running hot, Totally confused at this point.....can you please help

it sounds like either the radiator is clogged with debris or you may have a head gasket issues.

get it checked to be sure. my bet is on the radiator.
