working on an 05 dmax here. the heater will not get warm. replaced the heater core, and the thermostats. also the temp gauge gets hot to when driving it for sometime. the hoses that go into the firewall to the heater core are cold also after its up to temp. Also the EGR cooler is cold also. Anyone ever had this issue? its like the EGR cooler is plugged and coolant is not flowing through it but then i took the hose off the cooler that feeds the heater core, i filled the reservoir up with coolant and there was some coming out of there. but when i start it nothing comes out.
