Y block in a 56 Ford F-100 with original heater. Does it make any difference which order the hearter hoses are installed between the heater and the water pump and intake? If so, when heater connection is the outlet and which is the inlet?

Here is a picture of how mine was set up before pulling the motor.  It looks like the intake goes to the top and the water pump goes to the bottom.  It was not used much but when it was it worked fine.  Bing

The rule of thumb for heater hose connections is for the water flow to go into the heater core at the bottom connection and then out at the upper most hose connection.  This helps to purge the air from the core.  On the engine, the hose connection on the intake behind the thermostat is the pressure side which goes to the bottom of the core and the water pump is the suction side which in turn hooks to the top connection of the heater core.

Further to this post about water heater hoses. Is it feasible to hook the two heater hoses both to the water pump? My 58 Fairlane is being put back slowly together and my mechanic has hooked both hoses to the water pump. He says it looks better than the hose connecting to the outlet behind the thermostat on the intake manifold. I say he is wrong.



This is starting to become a nightmare and I wish I had the room to do the work myself.



Thanks again....

And right you are.  Both the 3/8” NPT connections at the water pump are the same in that they are suction or negative pressure.  Hooking up both heater hoses to the water pump will not provide circulation of coolant through the heater core and effectively not supply any heat.

Surely you have a driveway, or friends with a driveway, or better yet, friends with a garage. The few times I've had to let someone else work on my stuff, Ive regretted it. With all the flat rate bs, they just don't seem to share my attention to detail.

Common sense would tell the mechanic how the hoses hook up . Your mechanic must be a VW mechanic.

funny... mine (57 Fairlane) appears to be hooked up "backwards" (thermostat to top of core; H20 pump to bottom)... but I get warmed air when I run the heater...
