7mge replace

scarylarry · 02-25-2010, 06:17 AM

I am reinstalling the motor in the Supra I have a couple of issues. I have one wiring plug that I cannot figure out where it goes. I also have one small hose. with coolant from the head that I dont know where the othe end goes. I really need a better maual can I still get a "shop" manual from Toyota/ If not where can I get one with more detail in it? I have pics of the plug and hose but I am not smart enough to load them here? LOL ok figured out the pic thing #1 is where hose attaches to head this is toward front #2 Is plug this is towards rear of motor #3 is end of hose with a plug in it THANKS FOR THE HELP!!!

The coolant hose connects to the bottom coolant port on the ISCV (Idle Speed Control Valve). There's another nipple on top of the ISCV which runs to the throttle body and then there's another nipple on the throttle body which runs down to the metal hard pipe assembly near cylinders 5 and 6. So... the hose in front --> ISCV --> Throttle Body --> the plugged hose in back.

What colors are the wires running to that connector? Given it's location and that the wires look red and/or brown I'd hazard a guess that it's for the EGR VSV; Should be mounted under the intake plenum toward the rear. See 25860 here: http://www.cygnusx1.net/Supra/Librar...spx?F=1708&P=2

You should update your profile and possibly add a signature with the details of your car...

The link is to the TSRM (Toyota Service and Repair Manual) for the Toyota '90 or '91 Supra. There's presently a member selling one for a '91 in the classifieds section... if no one else gets it from him, I'm going to. IMHO, the TSRM is the best publication to have; the third party books are generally crap.

Hey thanks again your links on here are great!!!! I hope to get it running with info I have collected from you. I will give you an update and update my profile after. I had the motor completely rebuilt. Crank turned, block baked and checked then all new parts hope it will run like new.
