I have a s5 tii swapped 89 vert, and need help identifying a coolant hose.
Its right behind/underneath the throttle cable. I took a look in the FSM, but couldn't seem to find it. I need a name/part number/place I can buy one so I can make an attempt to replace it as it's created a legitimate waterfall of coolant underneath my beloved fc.
That seems to be this part number from the site the guy above me posted: 13-6810-N370. Coolant for this loop enters the back of the water pump housing, and if you trace it in reverse, it goes through the BACV, to the top of the throttle body, through the cold start cam thermowax, and then out the bottom of the throttle body straight into the block. That last part of the loop appears to be this hose. Just double check by pulling it off and looking at it first. It's a PITA to access and requires you to remove the UIM, throttle body, and throttle body elbow all in one go. Thanks to the age of our cars, I'd recommend ordering a replacement LIM-UIM gasket just to have handy if, when you remove the UIM, that gasket disintegrates. If you're ordering things off Mazdatrix, then it would be on this page: Intake Gaskets. You'll want P/N 13-112A-N370.
