I put in a new water pump and thermostat but motor still gets very hot very fast. I would like to find a hose routing diagram from radiator to motor then through the heater core to see if I crossed any hoses,,or maybe there's another reason for the extremely hot engine. I also did a flush to the system. Everything is clean now. Any help would be appreciated.

Could be air lock in the cooling system try bleeding it-don't work-Do below

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: ,Pressure test the Rad. cap,Clogged radiator,air lock in the cooling system ,Fan clutch,Radiator electrical fan,collaspe hoses,water pump
