Hook up heater core hoses

Re: heater core hook up « reply #6 on: october 09, 2009, 08:32:12 am » you'd just match the size of the hose to the inlet on the heater core as i believe they are 2 different sizes. I purchased a complete system from a member here i went to hook up the heater core to the hoses for the first start up and found out the the core has 2 - 5/8 spouts where my v6 has one 5/8 hose and one 3/4 hose. Part of the confusion is perhaps due to terminology the radiator lower hose is the suction/feed side for the wp, and suction/return by wp nipple for the heater core the pump pressurizes the block/head and thus the t-stat housing and upper radiator hose, which becomes feed for both radiator and heater core clear . When i installed the 408 in my mustang i decided i did not want to hook up the heater hoses for a couple of different reasons the car is only summer driven so i don't need any heat and i was also afraid of blowing the heater core.

Re: 94 range 23l heater core hose hook up help i'm not positive but i think the heater core is just an open loop so it should not really matter which way the hoses are hooked up on there but i may be wrong.

There is a inlet an outlet i have had it bypassed for so long can't remember for sure how to hook up hoses one hose is from water pump the other goes to engine if they are both the same size, it really doesn't make any difference, but if one is 3/4 and the other 5/8s the 3/4 is the hot side yeah. I don't think it matters which way you hook up the heater core, so why make them different every car i have, including my mercedes use 5/8 heater hoses, as best i recall sep 23, 2012 #11. Re: heater hose hook up the reason the coolant enters the bottom of the core is to have the coolant flow from bottom to top to get more heat out of the coolant while in the core before it is returned to the pump.

They should have cut hoses unless you pulled them off they will be very close to the back of your motor and like i said, one above the other i'd take pictures but my car is 3 hrs away from me and as for how they are connected to your heater core: ( ps i have an s14)you will need to do some trimming of the hoses.
