Over the past year I've become increasingly frustrated with GM replacement parts. Quality control has been terrible and it's caused me a lot of headaches when completing repairs.
My first experience was last fall when I attempted to replace forward lamp harness. I purchased the updated version from GM, carefully (and tediously) removed the old one from all the tight areas it was routed through and with almost as much difficulty, routed the new one into place. I made all the connections at the end devices (fans, horns, lights, sensors and washer fluid pump). My last and final connection was to snap the large (I believe) 68-cavity connector into the fuse box base and plug the fuse block back into the three mating connectors (main body harness, engine harness and forward lamp harness). Everything had gone relatively well, except that I just couldn't get the new forward lamp harness to mate with the fuse block. Upon closer examination, it was manufactured incorrectly. This large connector was rotated 180-degrees and the keys would not align properly. The parts department ordered a replacement and sure enough, it was correct.
Next, and something I'm still fighting with is my radiator replacement. I purchased an ACDelco OE radiator. Well, it's supposed to be OE but really isn't. Engineers, in their infinite wisdom, have changed the design of the fittings for the transmission cooler. They are low profile compared with the original version. First of all, the lower fitting (as per the documentation enclosed), will ALWAYS be for a threaded fitting on the transmission line. Well, mine wasn't. Whoever built it installed a quick connect fitting instead. No problem, so I thought. They were kind enough to include replacement that will accept a threaded line (although didn't include the seal needed for the line which I had to acquire separately). Off to the races I said! Oh, but then there was the upper fitting. It was the correct type (quick connect) only being low profile, the transmission line would not clip in. By securing the transmission line clamp to the fan shroud (as engineered), the line (or fitting, however you prefer to look at it) is too short. The parts department had no information in available engineering notes to offer a remedy. The parts department manager again helped me by contacting GM's ParTech (parts technical support line). Sure enough, they've seen this before! There is apparently another fitting I need that will extend the length so the line can now clip in properly. The part shows up today and as excited as a little kid on his birthday, I head off to pick it up. WTF!!! Sure, the fitting that arrived is a solution. Unfortunately, it threads into the fitting which I had to use to connect the lower line because (as I mentioned) they installed the wrong fitting in the bottom during manufacturing. So, Once again, I'm screwed. I'm now waiting for another one of those fittings used in the lower position. And guess what??? Nobody in Canada has one, it's stocked in Memphis TN.
My third issue is the brand new under hood electrical center. It's the identical part number to the one that came in the car and is factory populated with all the fuses, relays, circuit breaker and cover with fuse identification decal. Some of you may recall that I had Andrew do a little graphic work for me and I had new custom decals manufactured to correctly reflect the new electrical circuits for all my options. I looked over the new fuse block and suddenly thought I had made an error. The new fuse block shows one engine fan fused at 30A and the other fused at 40A. The factory installed fuses also reflect this. My custom decal is showing they should both be 30A?!?!? Well surprise!!! The new one is wrong. My old fuse block had two 30A fuses. I looked at a photo of my original fuse block decal (before modification), along with the GM service manual and the new one I purchased in January is incorrect.
Tonight I decided to get started on my power steering pressure line replacement. After everything I've been through so far, this should be a walk in the park. Well, one would think. The genuine GM part (which by the way is ONLY for the 2004-05 Bonneville with the LD8 engine) is again not quite like the original. There is a support around the line to attach it to the engine cradle. Well, they attached it several inches out of place. Fortunately, it wasn't too much work to carefully bend the crimped tabs holding it together so I could move it to the correct position. As long as I don't run into any other problems, this is minor. Still, yet another problem.
Seriously, is unreasonable to expect GM replacement parts to correct? These problems have all occurred over the past ten months. One of the reasons I spend the money on them is because they should (generally) be an identical replacement. These (big dollar) items have been nothing but a time consuming pain in my butt!
