There's a coolant line running from an outlet adaptor below the waterpump to the throttle body, and then another second line runs from the throttle body to... where exactly? Say I want to remove this second line - do I need to remove the UIM to get to it? A pic would be great!

thanks

 

Don't remove it! It goes to the back rotor somewhere. Can't remember where exactly.... Either way, it helps keeps temps even, and prevents hot spots. Very important for the car.

That's the throttle body bypass.

 

I don't want to remove it I want to replace it with a straight run of pipe since I've de-routed it from the throttle body anyways (we don't need TB heating in Oz) - hence I need to find where the other end of it is as such.

 

Yes I do believe you will need to remove the UIM.

I've got pictures somewhere I hope

 

The hose comes off the top, left side of the rear iron. (If facing the car) and runs to the thermostat area, you will need to remove the upper intake unless you have prehensile tentacle arms.

 

lol
win!

 

sorry no tentacle arms here and the trained mouse up and died last week so better factor in time to remove and replace the UIM!

Cheers for the tip!

 

Dunno if these help at all (camera phone pics sorry)

I'm pretty sure it's the hose in the center of the pic running from left to right. That's right where it connects to the iron.

 

Nice shot of your mechanicette there! Damn that thing is buried!

 

Hope this helps took me forever to find a good pic in my rebuild folder!

 

Thanks that does help - I've compromised for now - I'm replacing the front part of the hose and using a joiner into the original rear hose (cut down) - the idea being when I remove the UIM or more later for some other reason, I can do the join back to the rear outlet at that time.
