emil77, just do us all a favor and remove the pump... then place it on a flat surface.. measure the pump...and get a new one from the parts store... what store... you pick...!!!!
WE all want to see a picture of a new pump under the hood of your truck...
Very simple, short pump, water pump gaskets, bolts & you are taking pictures of a finished job that we all can be proud of!!!
just buy a short pump and 2 water pump gaskets for the year of truck... Measure the bolts and you are on your way to giving us the pictures we all want to see....
you can do this!!!!
