87 NA Coolant Line Diagram

kurth · 10-01-2011, 11:59 PM

Can anyone help us with finding a coolant line diagram for a 87 NA ? I have coolant leaking out of the driver side below the intake manifold and can not find where it needs to be hooked up to ?

Thanks

I received a 7MGE which was halfway through the head gasket job. I would like to know where the coolant hose labeled 16267 in this drawing connects on the top side. The other side goes to a 10mm-ish metal pipe near the starter.

This is the line I am talking about. I just need to know where it goes. 1988 Supra NA 7MGE.

Throttle body?

Yup. To the firewall side of the TB, then out from the forward side of the TB to the ISCV and then from the ISCV to the nipple on the lower intake runner flange.

Thanks, guys. It did go to the intake but that hose had been crammed on to the vacuum connection for the brake booster. Everything is cool now.

I could also use a little help with the wiring of the igniter/coil. All the wires are pulled out on the harness side...
