I just did a super clean on the vehicle myself and it had good heat during this procedure.I drained the super flush and added antifreeze at 50/50 mixture and once it was full I started the vehicle to let it warm up, the heat blowed warm so I took it for a drive, the longer drove, the cooler it got.I also changed the thermostat.I'm thinking of changing the waterpump, it doesn't seem like it circulates right.I was told that I might have a blowed head gasket or cracked head, no signs of leaking or loss of coolant, the oil is clean. Any ideas would be great, thanks Robert

Self purging system, the plastic tank where you fill the system at, automatically releases air from the system, I actually have good heat until I turn the blower on. Thanks for the reply

If you have good heat until the blower is turned on, then there isn't enough flow through the heater core. When you loose heat, do both heater core hoses stay hot?
