How essential is this piece? I was poking around the engine compartment on my parts car, and noticed that a hardware store elbow was in place where the secondary water pump should be. A quick check on ETKA revealed P/N 034 965 561 C is the part in question. All you 4kt guys out there using this part? If so, where'd you mount it? -Marc- 87 4kcsq awaiting turbo 87 5ktq donor
