I have a 93 isuzu rodeo I got it about 2 months ago there was no heater hoses to the heater core . changed the heater core with new one but I do not know what hose to place where .the heater core pipe from fire wall are top and bottom how does the hoses go one top of heater core to botton of moter someone help me .Is the inlet hose the top or bottom hose on the firewall ?
ha ha ive heard it dosent matter but it does matter just hook them up ,and if you hear a gurgeling coming from under the dash that means they are backwards air will get traped in the heater core and gurgle if it gurgles you have the charge hose on the bottom ..it wont hurt anything ,,,it just forces the air out when you start it ...Is the inlet hose the top or bottom hose on the firewall ?
It won't matter at all.
