Heater Hose routing.

scooterh72 · 05-12-2006, 02:28 AM

I just bought an 85 supra and the heater core was bypassed because it leaked. I just got done replacing it (yuck!) and need a diagram of the hose routing.

Thanks in advance.

how difficult was it to replace the heater core ?

the water comes out of the rear top center of the engines head and goes to the heater vsv switch on the firewall , then goes through the heater core and comes out the firewall near the egr valve

Actually it was kind of a pain. The only reason that I did it was they wanted $360 to do it at a shop. (I already had the heater core). Definatley plan on devoting the better part of a day.
