S14 SR Heater Core Hoses

[dfroese]

I just finished an s14 sr swap into my s13. i'm not sure which of the two heater core hoses goes to which of the two ports on the firewall. on the engine there is the one hose closest to the engine, and then one farthest away from the engine (s14 sr heater core system is different than the s13 sr). and on the firewall, there's a top port and a bottom one. Does anyone know which hose goes to which port? or even the direction of flow for the s13 chassis heater core. Thanks.

The one that makes the "U" at the back of the head goes to the top nipple on the fire wall.

The one that comes from the coolant lines underneath the intake mani goes to the bottom nipple on the firewall.

Umm, No.

BRB Let me go check my engine for you.

The one closest to the Passenger fender will go to the top. The one closest to the engine will be the bottom one.

Ilikemy240SX, The S14 SR doesnt have the Hard line bull crap. You have 2 REALLY long soft rubber hoses.

The jdm hoses are more than enough hose to trim and re-use for your usdm heater core.

Thanks soooo much. i've been looking all over for this info, but couldnt find it. its getting colder out these days, and the defrost doesnt work well without heat.
