Yes...there is a T-Stat...and has anyone ran it outside the water since you put the new pump in?<br /><br />Also check the compression. You could have blown the head gasket.<br /><br />TMD

When you reinstalled the LU after impeller change did you make absolutely sure that the water tube was correctly seated at the pump end AND the powerhead end? You may need to remove the motor leg to find out. Not a big job to do.
