throttle body coolant lines

GreenMachine · Post by **GreenMachine** » September 9th, 2006, 4:35 am

ok Ive almost got the ze swap finished, and now I have to find where the coolant lines come from/go to the throttle body. I have the one hooked up correctly in the front, but where does the one on the back of the throttle body hook up to? Also on the radiator, drivers side there is a nipple coming out of the top about the same size as the over flow line. what is supposed to hook up to this nipple? I searched but turned no usable results. and btw, thanks to the site for helping with the info to get the ze in there!

One goes to a nipple on the rear head. The other goes to a nipple on the EGR.

There should be a nipple on the rear head and a nipple on the Thermostat Housing on the back. It does run through the EGR but not on my car. Just staright into the throtle body since i don't have egr.

ok well I have the egr on there for cali smog. so lets see if i have this right. nipple on rear head ->throttle body front->throttle body rear->nipple on egr. is that correct? and i thought the thermostat housing was on the other side of the motor, no?

oh ok. just seemed funny to me that it ends at the egr. does the egr route the water back into the block at all?
