My 1999 jeep cherokee sport has hardly any heat at all. Gunk keeps building up in my cooling system, I've had it flushed multiple times within the past year. I just replaced water pump and there are no bubbles in my oil, so I don't think it's a head gasket. I heard my radiator could be causing the gunk and may need replaced. Is there anything else if could be?

Chances are the radiator is gunked up bad. My 88 was packed solid. Best bet is to replace it, and the t-stat at the same time. Flush the block and heater core when you take out the old radiator so all the gunk is gone.
