1. I have a blazer with air, heater hose goes to the water pump. No hole in radiator for the hose. I think after market 4-core radiator

2. I have a pickup with air, heater hose goes to the radiator. There's a plug in the water pump where hose would go. gm 4-core Harrison's

Can anyone tell me why this is or if one way is correct for a 71 air pickup. Thanks
