1995 regal heat

no heat installed new heater core hoses checked all inlets outlets for blockage
new thermostat new radiator. still no heat. would appreciate any suggestions

If temp doors are okay and heater hoses are NOT warm, then you need to bleed the air out- use the bleeder screw on top of water outlet (thermostat) housing. Or sometime it helps to "preload" system- unhook hoses and prime them with coolant.

Agree....air bound or a temp door problem....
