If it was running hot before the repair and you have a Northstar engine you need to have the cooling system tested for exhaust gases. It's probably the head gaskets. All Northstar engines blow head gaskets!! If it wasn't running hot before the repair and now is, you probably have air trapped in the cooling system. Check your serpentine belt for proper routing as well. HTH. - Jim
