Engine Coolant Recovery Tank with Sensor 25774005 Fit for Cadillac Deville Oldsmobile Aurora Pontiac Bonneville Fits select: 2004 CADILLAC PROFESSIONAL CHASSIS, 2004-2005 PONTIAC BONNEVILLE GXP

I like the design, the fact that the included sensor works, and the design is pretty much the same as the original one. I was hesitant first about the cap though because it's one psi less than the OE one. It's 17 psi instead of 18 and I also thought that the cap was a little less than durable. However, I was completely wrong. The sensor works, and it did tell me the time that my coolant was low when I was refilling the system ever since my check engine coolant has not came on. If the cap is on there properly, it works effectively. NO! It's not an AC Delco, but why keep paying outrageous prices for original equipment when there are so many compatible brands, that either meet standard requirements or supersede them? I've come to learn that there are many products that are better than AC Delco parts, in my opinion anyway. I am a woman who has been learning to work on her own Northstar engine, because I got tired of being ripped off by all of the shops who would maliciously cause other problems just for me to bring them back in and spend more money. However, I'm grateful that they did because working on your own car is much more time-consuming, but less stressful and less expensive and if something goes wrong, the only one to blame is yourself. After all, even if it's the fault, good luck we're trying to get your money back, or your vehicle when you don't decide to pay the money for their mistakes. The only other option is to sue them and small claims court and good luck with that and dealing with the injustice system. Anyway, I highly recommend this part as someone who has switched out her own expansion tank and no longer experiencing problems I once was, and all so much cheaper than a brand name part and a shady mechanic shop charging an arm in a leg to replace the darn thing.
