Where do I find a new elbow?
97-98 Throttle body w/coolant tree.
Hot coolant travels through the tree and taps into the heater core line behind the lower intake. This helps heat the plenum. The PCV line which plugs into the tree in line with the plenum and re-enters in back of the manifold also helps heat the plenum. It's the Cold Climate System used in the 97-98 model years. These systems may be in later models , I haven't seen one in a 99 yet.
