if it's a fullsize and it's like my 90 1/2 ton, then you might have the
infamous "thermal actuator" and it might be toast or it's just taking a
long time to engage. (whatta stupid design. my S15 Jimmy had a vacuum
actuator that didn't do that, and the parts pricing for a new one is
insane.)

Do a quick google for thermal actuator chevy...
